Ubuntu 22.04 使用 Podman 部署 OpenGrok 的详细教程

安装必要的依赖:

# 安装 podman
$ sudo apt install podman

# 安装 git
$ sudo apt install git

# 创建一个低权限用户，尽量不要使用root用户，身份操作podman,降低安全风险
$ sudo adduser podman

# 允许用户下的容器在系统启动的时候启动服务
$ sudo loginctl enable-linger podman

# 切换到刚刚创建的低权限用户 ,注意，必须使用 su - user 的方式切换
# 如果使用 su user 切换会导致环境变量被带到新用户，导致执行报错
# ERRO[0000] XDG_RUNTIME_DIR directory "/run/user/1000" is not owned by the current user 

$ su - podman

# 准备本地目录映射
$ mkdir ~/.dockers

$ mkdir ~/.dockers/opengrok

# 准备已经处理过的源代码，源代码需要 src、etc、data 三个目录，src存储源代码，其他目录保持空即可
# 参考 https://www.mobibrw.com/2019/19162
# 更详细的处理参考官方文档即可，后续我们以 Android 4.2.2 的源代码为例子

# Android 4.2.2 源代码存放在 ~/.dockers/opengrok/Android_4.2.2/src
$ mkdir ~/.dockers/opengrok/Android_4.2.2/src

$ mkdir ~/.dockers/opengrok/Android_4.2.2/etc

$ mkdir ~/.dockers/opengrok/Android_4.2.2/data

# 手工拉去部分镜像，或者可以在 /etc/containers/registries.conf 配置镜像服务器，可省略前面的服务器 docker.io
$ podman pull docker.io/library/tomcat:10-jdk17

$ podman pull docker.io/library/tomcat:10.1-jdk17

# 安装 podman

$ sudo apt install podman

# 安装 git

$ sudo apt install git

# 创建一个低权限用户，尽量不要使用root用户，身份操作podman,降低安全风险

$ sudo adduser podman

# 允许用户下的容器在系统启动的时候启动服务

$ sudo loginctl enable-linger podman

# 切换到刚刚创建的低权限用户 ,注意，必须使用 su - user 的方式切换

# 如果使用 su user 切换会导致环境变量被带到新用户，导致执行报错

# ERRO[0000] XDG_RUNTIME_DIR directory "/run/user/1000" is not owned by the current user

$ su - podman

# 准备本地目录映射

$ mkdir ~/.dockers

$ mkdir ~/.dockers/opengrok

# 准备已经处理过的源代码，源代码需要 src、etc、data 三个目录，src存储源代码，其他目录保持空即可

# 参考 https://www.mobibrw.com/2019/19162

# 更详细的处理参考官方文档即可，后续我们以 Android 4.2.2 的源代码为例子

$ mkdir ~/.dockers/opengrok/Android_4.2.2/src

$ mkdir ~/.dockers/opengrok/Android_4.2.2/etc

$ mkdir ~/.dockers/opengrok/Android_4.2.2/data

# 手工拉去部分镜像，或者可以在 /etc/containers/registries.conf 配置镜像服务器，可省略前面的服务器 docker.io

$ podman pull docker.io/library/tomcat:10-jdk17

$ podman pull docker.io/library/tomcat:10.1-jdk17

官方镜像会在报错的时候暴露 Tomcat 10 版本号，错误堆栈，构成安全隐患，我们需要通过构建自定义镜像解决此问题:

# 目前最新代码 commit ad9658443340a6dae425d94ab7cb0cc9d74fb37f
$ git clone https://github.com/oracle/opengrok.git

$ cd opengrok

# 设置 maven 国内代理，否则下载速度太慢了 
$ find . -type f -exec grep -l "repo.maven" {} \; | xargs sed -i "s/repo.maven.apache.org\/maven2\//mirrors.cloud.tencent.com\/nexus\/repository\/maven-public\//"

# 设置 Maven Wrapper 国内源
$ sed -i "s/repo.maven.apache.org\/maven2\//mirrors.cloud.tencent.com\/nexus\/repository\/maven-public\//" .mvn/wrapper/maven-wrapper.properties

# 代码中使用的 linux 系统镜像版本，我们需要明确告知 podman 从 docker.io 获取
$ sed -i "s/ubuntu:jammy/docker.io\/ubuntu:jammy/g" Dockerfile

# 代码中使用的 Tomcat 镜像版本，不能通过 docker.io 获取到，我们直接使用通用 Tomcat 10 版本
$ sed -i "s/tomcat:10.1.19-jdk17/docker.io\/library\/tomcat:10.1-jdk17/g" Dockerfile

$ sed -i "s/tomcat:10.1.30-jdk17/docker.io\/library\/tomcat:10.1-jdk17/g" Dockerfile

# 目前最新代码 commit ad9658443340a6dae425d94ab7cb0cc9d74fb37f

$ git clone https://github.com/oracle/opengrok.git

$ cd opengrok

# 设置 maven 国内代理，否则下载速度太慢了

$ find . -type f -exec grep -l "repo.maven" {} \; | xargs sed -i "s/repo.maven.apache.org\/maven2\//mirrors.cloud.tencent.com\/nexus\/repository\/maven-public\//"

# 设置 Maven Wrapper 国内源

$ sed -i "s/repo.maven.apache.org\/maven2\//mirrors.cloud.tencent.com\/nexus\/repository\/maven-public\//" .mvn/wrapper/maven-wrapper.properties

# 代码中使用的 linux 系统镜像版本，我们需要明确告知 podman 从 docker.io 获取

$ sed -i "s/ubuntu:jammy/docker.io\/ubuntu:jammy/g" Dockerfile

# 代码中使用的 Tomcat 镜像版本，不能通过 docker.io 获取到，我们直接使用通用 Tomcat 10 版本

$ sed -i "s/tomcat:10.1.19-jdk17/docker.io\/library\/tomcat:10.1-jdk17/g" Dockerfile

$ sed -i "s/tomcat:10.1.30-jdk17/docker.io\/library\/tomcat:10.1-jdk17/g" Dockerfile

需要额外注意的一个地方是，给出的路径必须是完整路径 “/home/podman/.dockers/opengrok/Android_4.2.2/src”，不能是 “~/.dockers/opengrok/Android_4.2.2/src”，Systemd不能正确展开 “~” ，导致路径找不到，从而在启动的时候失败，报告错误代码 125 。

另外，Android源代码目录下不能存在 .svn .git 隐藏子目，我们需要手工删除，否则会报错。参考删除目录下所有的 .svn .git 隐藏子目

Running containers with resource limits fails with a permissions error

On some systemd-based systems, non-root users do not have resource limit delegation permissions. This causes setting resource limits to fail.

Symptom

Running a container with a resource limit options will fail with an error similar to the following:

--cpus, --cpu-period, --cpu-quota, --cpu-shares:

Error: OCI runtime error: crun: the requested cgroup controller `cpu` is not available

1	Error: OCI runtime error: crun: the requested cgroup controller `cpu` is not available

--cpuset-cpus, --cpuset-mems:

Error: OCI runtime error: crun: the requested cgroup controller `cpuset` is not available

1	Error: OCI runtime error: crun: the requested cgroup controller `cpuset` is not available

This means that resource limit delegation is not enabled for the current user.

Solution

You can verify whether resource limit delegation is enabled by running the following command:

$ cat "/sys/fs/cgroup/user.slice/user-$(id -u).slice/user@$(id -u).service/cgroup.controllers"

1	$ cat "/sys/fs/cgroup/user.slice/user-$(id -u).slice/user@$(id -u).service/cgroup.controllers"

Example output might be:

memory pids

1	memory pids

In the above example, cpu and cpuset are not listed, which means the current user does not have permission to set CPU or CPUSET limits.

If you want to enable CPU or CPUSET limit delegation for all users, you can create the file /etc/systemd/system/user@.service.d/delegate.conf with the contents:

[Service] 
Delegate=memory pids cpu cpuset

1 2	[Service] Delegate=memory pids cpu cpuset

After logging out and logging back in, you should have permission to set CPU and CPUSET limits.

Ubuntu 22.04使用Podman部署Tomcat 10的详细教程

安装必要的依赖:

# 安装 podman
$ sudo apt install podman

# 创建一个低权限用户，尽量不要使用root用户，身份操作podman,降低安全风险
$ sudo adduser podman

# 允许用户下的容器在系统启动的时候启动服务
$ sudo loginctl enable-linger podman

# 退出当前用户，切换到刚刚创建的低权限用户, 注意，不要使用 su - user 的方式切换，后续会执行各种报错
# 如果使用 su user 切换会导致环境变量被带到新用户，导致执行报错
# ERRO[0000] XDG_RUNTIME_DIR directory "/run/user/1000" is not owned by the current user 
# Error running systemd as user - Failed to connect to bus: $DBUS_SESSION_BUS_ADDRESS and $XDG_RUNTIME_DIR not defined

$ exit

# 通过 ssh 登录用户名 podman 密码是创建用户的时候设置的密码

# 准备本地目录映射
$ mkdir ~/.dockers/tomcat

$ mkdir ~/.dockers/tomcat/webapps

$ mkdir ~/.dockers/tomcat/logs

# 安装 podman

$ sudo apt install podman

# 创建一个低权限用户，尽量不要使用root用户，身份操作podman,降低安全风险

$ sudo adduser podman

# 允许用户下的容器在系统启动的时候启动服务

$ sudo loginctl enable-linger podman

# 退出当前用户，切换到刚刚创建的低权限用户, 注意，不要使用 su - user 的方式切换，后续会执行各种报错

# 如果使用 su user 切换会导致环境变量被带到新用户，导致执行报错

# Error running systemd as user - Failed to connect to bus: $DBUS_SESSION_BUS_ADDRESS and $XDG_RUNTIME_DIR not defined

$ exit

# 通过 ssh 登录用户名 podman 密码是创建用户的时候设置的密码

# 准备本地目录映射

$ mkdir ~/.dockers/tomcat

$ mkdir ~/.dockers/tomcat/webapps

$ mkdir ~/.dockers/tomcat/logs

官方镜像会在报错的时候暴露 Tomcat 10 版本号，错误堆栈，构成安全隐患，我们需要通过构建自定义镜像解决此问题:

$ touch Dockerfile

1	$ touch Dockerfile

内容如下：

# 详细启动日志在 /usr/local/tomcat/logs 目录下

From docker.io/library/tomcat:10

# xml 编辑工具，方便我们后续修改 tomcat 的xml配置文件
# RUN apt update && apt install -y xmlstarlet

# 增加 <Valve className="org.apache.catalina.valves.ErrorReportValve" showReport="false" showServerInfo="false" /> 阻止错误日志输出

RUN sed -i "s/<\/Host>/  <Valve className='org.apache.catalina.valves.ErrorReportValve' showReport='false' showServerInfo='false' \/>\n\t<\/Host>/" /usr/local/tomcat/conf/server.xml

把系统从Struts2 迁移到 Spring MVC六大步总结

基于struts的系统迁移到SpringMVC架构上来，共分六部曲，让系统一部一部迁移过来，本文讲的知识点以Struts2 to Spring4，但是针对其他应用场景也是可以参考的。

Step 1: 替换基本的框架库。

Firstly while migrating from struts to spring we have to replace our struts related libraries with spring libraries in lib folder.

I have mentioned basic libraries of both struts and spring for your clarification.

Struts basic libraries :

struts.jar
struts-legacy.jar
etc..

Have you ever use : Javadoc comment in Java

Spring basic libraries :

standard.jar
org.springframework.asm-4.0.1.RELEASE-A.jar
org.springframework.beans-4.0.1.RELEASE-A.jar
org.springframework.context-4.0.1.RELEASE-A.jar
org.springframework.core-4.0.1.RELEASE-A.jar
org.springframework.expression-4.0.1.RELEASE-A.jar
org.springframework.web.servlet-4.0.1.RELEASE-A.jar
org.springframework.web-4.0.1.RELEASE-A.jar
etc..

Step 2: 修改web.xml配置文件

In this step we have to remove Action filter dispatcher for the web.xml and add Spring dipatcher servlet as Front controller
Work on new technology : Create and manage cloud applications using Java

In Strut application web.xml look like as follows

<?xml version="1.0" encoding="UTF-8"?>  
<web-app xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns="http://java.sun.com/xml/ns/javaee" xmlns:web="http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd" xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_3_0.xsd" id="WebApp_ID" version="3.0">

            org.apache.struts2.dispatcher.FilterDispatcher  
        </filter-class>  
    </filter>  

<filter-mapping>  
        <filter-name>struts2</filter-name>  
        <url-pattern>/*</url-pattern>  
    </filter-mapping>  
    <welcome-file-list>  
        <welcome-file>Login.jsp</welcome-file>  
    </welcome-file-list>  
</web-app>

<?xml version="1.0" encoding="UTF-8"?>

<web-app xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns="http://java.sun.com/xml/ns/javaee" xmlns:web="http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd" xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_3_0.xsd" id="WebApp_ID" version="3.0">

</filter-class>

</filter>

<filter-mapping>

<url-pattern>/*</url-pattern>

</filter-mapping>

<welcome-file-list>

<welcome-file>Login.jsp</welcome-file>

</welcome-file-list>

</web-app>

In Spring application web.xml look like as follows

<?xml version="1.0" encoding="UTF-8"?>  
<web-app xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns="http://java.sun.com/xml/ns/javaee" xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_3_0.xsd" id="WebApp_ID" version="3.0">

  <servlet>  
    <servlet-name>dispatcher</servlet-name>  
    <servlet-class>  
            org.springframework.web.servlet.DispatcherServlet  
        </servlet-class>  
    <load-on-startup>1</load-on-startup>  
  </servlet>  
  <servlet-mapping>  
    <servlet-name>dispatcher</servlet-name>

  </servlet-mapping>  
</web-app>

<?xml version="1.0" encoding="UTF-8"?>

<web-app xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns="http://java.sun.com/xml/ns/javaee" xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_3_0.xsd" id="WebApp_ID" version="3.0">

</servlet>

<servlet-mapping>

<servlet-name>dispatcher</servlet-name>

<url-pattern>/</url-pattern>

</servlet-mapping>

</web-app>

Step 3: 替换Struts本身的配置文件

Now replace all struts configuration files to spring configuration file as follows

In Struts applivation struts configuration file-

<?xml version="1.0" encoding="UTF-8" ?>  
<!DOCTYPE struts PUBLIC  
    "-//Apache Software Foundation//DTD Struts Configuration 2.0//EN"  
    "http://struts.apache.org/dtds/struts-2.0.dtd">  
   
<struts>  
    <constant name="struts.enable.DynamicMethodInvocation" value="false" />  
    <constant name="struts.devMode" value="false" />  
    <constant name="struts.custom.i18n.resources" value="myapp" />  
   
    <package name="default" extends="struts-default" namespace="/">  
        <action name="login" class="com.geekonjavaonjava.struts2.login.LoginAction">  
            <result name="success">Welcome.jsp</result>  
            <result name="error">Login.jsp</result>  
        </action>  
    </package>  
</struts>

<?xml version="1.0" encoding="UTF-8" ?>

<!DOCTYPE struts PUBLIC

"-//Apache Software Foundation//DTD Struts Configuration 2.0//EN"

"http://struts.apache.org/dtds/struts-2.0.dtd">

<result name="success">Welcome.jsp</result>

<result name="error">Login.jsp</result>

</action>

</package>

</struts>

In Spring application spring configuration file as follows

<?xml version="1.0" encoding="UTF-8"?>    
<beans xmlns="http://www.springframework.org/schema/beans"    
     xmlns:context="http://www.springframework.org/schema/context"    
     xmlns:p="http://www.springframework.org/schema/p"      
     xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"    
     xsi:schemaLocation="http://www.springframework.org/schema/beans    
    http://www.springframework.org/schema/beans/spring-beans-4.0.xsd    
    http://www.springframework.org/schema/context    
    http://www.springframework.org/schema/context/spring-context-4.0.xsd">

Here, <context:component-scan> tag is used, so that spring will load all the components from given package i.e. " com.geekonjavaonjava.spring.login.controller".

Use this in Struts2 : Get value of struts property tag into jsp variable

We can use different view resolver, here I have used InternalResourceViewResolver. In which prefix and suffix are used to resolve the view by prefixing and suffixing values to the object returned by ModelAndView in action class.

Step 4: 修改JSP文件

While migration an application from struts to spring we need to change in jsp file as following

Firstly replace all tlds-

<%@ taglib uri="http://struts.apache.org/tags-bean" prefix="bean" %>  
<%@ taglib uri="http://struts.apache.org/tags-html" prefix="html" %>  
<%@ taglib uri="http://struts.apache.org/tags-logic" prefix="logic" %>  
<%@ taglib uri="http://struts.apache.org/tags-tiles" prefix="tiles" %>

<%@ taglib uri="http://struts.apache.org/tags-bean" prefix="bean" %>

<%@ taglib uri="http://struts.apache.org/tags-html" prefix="html" %>

<%@ taglib uri="http://struts.apache.org/tags-logic" prefix="logic" %>

<%@ taglib uri="http://struts.apache.org/tags-tiles" prefix="tiles" %>

Replace these with following spring taglib's :

<%@ taglib prefix="form" uri="http://www.springframework.org/tags/form"%>  
<%@ taglib prefix="spring" uri="http://www.springframework.org/tags"%>

1 2	<%@ taglib prefix="form" uri="http://www.springframework.org/tags/form"%> <%@ taglib prefix="spring" uri="http://www.springframework.org/tags"%>

In Struts :

<html:form action="/addLogin" method="post">

1	<html:form action="/addLogin" method="post">

In Spring :

<form:form method="POST" commandName="loginForm" name="loginForm" action="login.do">

1	<form:form method="POST" commandName="loginForm" name="loginForm" action="login.do">

Here commandName is going to map with corresponding formbean for that jsp. Next we will see, how action is getting called with spring 4 annotations.

Step 5: 修改Action 类文件

Now following changes need to be done in action classes for struts to spring migration using annotations-

Struts Action:

package com.geekonjavaonjava.struts2.login;  
  
import com.opensymphony.xwork2.ActionSupport;  
  
/** 
 * @author geekonjava 
 * 
 */  
@SuppressWarnings("serial")  
public class LoginAction  extends ActionSupport{  
 private String username;  
    private String password;  
      
 public String execute() {  
     
        if (this.username.equals("geekonjava")   
                && this.password.equals("sweety")) {  
            return "success";  
        } else {  
         addActionError(getText("error.login"));  
            return "error";  
        }  
    }  
  
 public String getUsername() {  
  return username;  
 }  
  
 public void setUsername(String username) {  
  this.username = username;  
 }  
  
 public String getPassword() {  
  return password;  
 }  
  
 public void setPassword(String password) {  
  this.password = password;  
 }  
   
}

package com.geekonjavaonjava.struts2.login;

import com.opensymphony.xwork2.ActionSupport;

/**

* @author geekonjava

@SuppressWarnings("serial")

public class LoginAction extends ActionSupport{

private String username;

private String password;

public String execute() {

if (this.username.equals("geekonjava")

&& this.password.equals("sweety")) {

return "success";

} else {

addActionError(getText("error.login"));

return "error";

}

public String getUsername() {

return username;

}

public void setUsername(String username) {

this.username = username;

}

public String getPassword() {

return password;

}

public void setPassword(String password) {

this.password = password;

}

Spring action

package com.geekonjavaonjava.spring.login.controller;  
  
import org.springframework.stereotype.Controller;  
import org.springframework.ui.ModelMap;  
import org.springframework.web.bind.annotation.RequestMapping;  
import org.springframework.web.bind.annotation.RequestMethod;  
  
/** 
 * @author GeekOnJava 
 * 
 */  
@Controller  
public class LoginController {  
   
 @RequestMapping(value="/login.do", method = RequestMethod.GET)  
 public String doLogin(ModelMap model, LoginForm loginForn) {  
 if (this.username.equals("geekonjava")   
                && this.password.equals("sweety")) {  
            model.addAttribute("message", "Login Success");  
        } else {  
            model.addAttribute("message", "Login Failure");  
        }  
         return "home";  
   
 }  
}

package com.geekonjavaonjava.spring.login.controller;

import org.springframework.stereotype.Controller;

import org.springframework.ui.ModelMap;

import org.springframework.web.bind.annotation.RequestMapping;

import org.springframework.web.bind.annotation.RequestMethod;

/**

* @author GeekOnJava

@Controller

public class LoginController {

@RequestMapping(value="/login.do", method = RequestMethod.GET)

public String doLogin(ModelMap model, LoginForm loginForn) {

if (this.username.equals("geekonjava")

&& this.password.equals("sweety")) {

model.addAttribute("message", "Login Success");

} else {

model.addAttribute("message", "Login Failure");

}

return "home";

}

Step 6: 修改前端验证机制

In struts JSP file validation changes as follows

<% ActionErrors actionErrors = (ActionErrors)request.getAttribute("org.apache.struts.action.ERROR"); %>

1	<% ActionErrors actionErrors = (ActionErrors)request.getAttribute("org.apache.struts.action.ERROR"); %>

In Spring JSP file as follows-

<form:errors path="*" cssClass="error" />

1	<form:errors path="*" cssClass="error" />

Android: 通过Intent筛选多种类型文件

一般使用setType()方法来实现文件过滤，如：只显示PDF文件：

     int requestCode = 100;
     Intent intent = new Intent(Intent.ACTION_GET_CONTENT);
     intent.setType("application/pdf");
     intent.addCategory(Intent.CATEGORY_OPENABLE);
     startActivityForResult(intent, requestCode);

int requestCode = 100;

Intent intent = new Intent(Intent.ACTION_GET_CONTENT);

intent.setType("application/pdf");

intent.addCategory(Intent.CATEGORY_OPENABLE);

startActivityForResult(intent, requestCode);

但如果要指定多种类型呢，同时要指定pdf,excel,word,ppt这些类型的文件，那要怎样设置呢？

指定多种类型文件

在网上查了，有些答案是

错误方式1——setType中进行拼接：

intent.setType(“video/*;image/*”);//同时选择视频和图片

1	intent.setType(“video/;image/”);//同时选择视频和图片

错误方式2——调用多次setType：

intent.setType("video/*");
intent.setType("image/*");

1 2	intent.setType("video/"); intent.setType("image/");

这两种方式都是错误的

我们看下源码

/**
     * Set an explicit MIME data type.
     *
     * <p>This is used to create intents that only specify a type and not data,
     * for example to indicate the type of data to return.
     *
     * <p>This method automatically clears any data that was
     * previously set (for example by {@link #setData}).
     *
     * <p><em>Note: MIME type matching in the Android framework is
     * case-sensitive, unlike formal RFC MIME types.  As a result,
     * you should always write your MIME types with lower case letters,
     * or use {@link #normalizeMimeType} or {@link #setTypeAndNormalize}
     * to ensure that it is converted to lower case.</em>
     *
     * @param type The MIME type of the data being handled by this intent.
     *
     * @return Returns the same Intent object, for chaining multiple calls
     * into a single statement.
     *
     * @see #getType
     * @see #setTypeAndNormalize
     * @see #setDataAndType
     * @see #normalizeMimeType
     */
    public Intent setType(String type) {
        mData = null;
        mType = type;
        return this;
    }

/**

* Set an explicit MIME data type.

* This is used to create intents that only specify a type and not data,

* @see #normalizeMimeType

public Intent setType(String type) {

mData = null;

mType = type;

return this;

}

我们可以看到，setType每次都是重新赋值，没有添加到list和数组中，因此这两种方式是实现不了指定多种类型文件的。
既然这种方式实现不了，那么Intent会不会提供字段以便我们传递过滤数据，我们通过官方文档及源码，发现Intent提供了EXTRA_MIME_TYPES这个字段来传递，而且是数组类型：

/**
     * Extra used to communicate a set of acceptable MIME types. The type of the
     * extra is {@code String[]}. Values may be a combination of concrete MIME
     * types (such as "image/png") and/or partial MIME types (such as
     * "audio/*").
     *
     * @see #ACTION_GET_CONTENT
     * @see #ACTION_OPEN_DOCUMENT
     */
    public static final String EXTRA_MIME_TYPES = "android.intent.extra.MIME_TYPES";

/**

* Extra used to communicate a set of acceptable MIME types. The type of the

* extra is {@code String[]}. Values may be a combination of concrete MIME

* types (such as "image/png") and/or partial MIME types (such as

* "audio/*").

* @see #ACTION_GET_CONTENT

* @see #ACTION_OPEN_DOCUMENT

public static final String EXTRA_MIME_TYPES = "android.intent.extra.MIME_TYPES";

因此结果就简单了,我们要指定ppt,word,excel,pdf类型的文件，代码如下

public static void openDirChooseFile(Activity activity, int requestCode, String[] mimeTypes) {
        Intent intent = new Intent(Intent.ACTION_GET_CONTENT);
        if (mimeTypes != null) {
            intent.putExtra(Intent.EXTRA_MIME_TYPES, mimeTypes);
        }
        intent.setType("*/*");
        intent.addCategory(Intent.CATEGORY_OPENABLE);
        // intent.putExtra(Intent.EXTRA_ALLOW_MULTIPLE, true);//多选
        activity.startActivityForResult(intent, requestCode);
    }
 public static void chooseFile(Activity activity, int requestCode) {
        String[] mimeTypes = {MimeType.DOC, MimeType.DOCX, MimeType.PDF, MimeType.PPT, MimeType.PPTX, MimeType.XLS, MimeType.XLSX};
        FileUtil.openDirChooseFile(activity, requestCode, mimeTypes);
    }

public static void openDirChooseFile(Activity activity, int requestCode, String[] mimeTypes) {

Intent intent = new Intent(Intent.ACTION_GET_CONTENT);

if (mimeTypes != null) {

intent.putExtra(Intent.EXTRA_MIME_TYPES, mimeTypes);

}

intent.setType("*/*");

intent.addCategory(Intent.CATEGORY_OPENABLE);

// intent.putExtra(Intent.EXTRA_ALLOW_MULTIPLE, true);//多选

activity.startActivityForResult(intent, requestCode);

}

public static void chooseFile(Activity activity, int requestCode) {

String[] mimeTypes = {MimeType.DOC, MimeType.DOCX, MimeType.PDF, MimeType.PPT, MimeType.PPTX, MimeType.XLS, MimeType.XLSX};

FileUtil.openDirChooseFile(activity, requestCode, mimeTypes);

}

MimeType文件

public class MimeType {
    public static final String DOC = "application/msword";
    public static final String DOCX = "application/vnd.openxmlformats-officedocument.wordprocessingml.document";
    public static final String XLS = "application/vnd.ms-excel application/x-excel";
    public static final String XLSX = "application/vnd.openxmlformats-officedocument.spreadsheetml.sheet";
    public static final String PPT = "application/vnd.ms-powerpoint";
    public static final String PPTX = "application/vnd.openxmlformats-officedocument.presentationml.presentation";
    public static final String PDF = "application/pdf";
}

public class MimeType {

public static final String DOC = "application/msword";

public static final String DOCX = "application/vnd.openxmlformats-officedocument.wordprocessingml.document";

public static final String XLS = "application/vnd.ms-excel application/x-excel";

public static final String XLSX = "application/vnd.openxmlformats-officedocument.spreadsheetml.sheet";

public static final String PPT = "application/vnd.ms-powerpoint";

public static final String PPTX = "application/vnd.openxmlformats-officedocument.presentationml.presentation";

public static final String PDF = "application/pdf";

}

Intent指定多种类型的文件，正确的做法，是通过Intent.EXTRA_MIME_TYPES传递Mime类型数组实现

 intent.setType("*/*");
 intent.putExtra(Intent.EXTRA_MIME_TYPES, mimeTypes);

1 2	intent.setType("/"); intent.putExtra(Intent.EXTRA_MIME_TYPES, mimeTypes);

Ubuntu 22.04使用Podman部署Tomcat 9的详细教程

安装必要的依赖:

# 安装 podman
$ sudo apt install podman

# 准备本地目录映射
$ mkdir /home/data/.tomcat

$ mkdir /home/data/.tomcat/webapps

$ mkdir /home/data/.tomcat/logs

# 安装 podman

$ sudo apt install podman

# 准备本地目录映射

$ mkdir /home/data/.tomcat

$ mkdir /home/data/.tomcat/webapps

$ mkdir /home/data/.tomcat/logs

官方镜像会在报错的时候暴露 Tomcat 9 版本号，错误堆栈，构成安全隐患，我们需要通过构建自定义镜像解决此问题:

$ touch Dockerfile

1	$ touch Dockerfile

内容如下：

# 详细启动日志在 /usr/local/tomcat/logs 目录下

From docker.io/library/tomcat:9

# xml 编辑工具，方便我们后续修改 tomcat 的xml配置文件
# RUN apt update && apt install -y xmlstarlet

# 增加 <Valve className="org.apache.catalina.valves.ErrorReportValve" showReport="false" showServerInfo="false" /> 阻止错误日志输出

RUN sed -i "s/<\/Host>/  <Valve className='org.apache.catalina.valves.ErrorReportValve' showReport='false' showServerInfo='false' \/>\n\t<\/Host>/" /usr/local/tomcat/conf/server.xml

# 配置AJP协议
# 如果只希望通过 AJP访问，可以参考如下命令 移除原有的 AJP 协议配置
# RUN xmlstarlet ed -L -P -S -d '/Server/Service/Connector' /usr/local/tomcat/conf/server.xml

# 增加新的协议配置
RUN sed -i "s/<\/Service>/  <Connector port='8009' protocol='AJP\/1.3' address='0.0.0.0' redirectPort='8443' secretRequired=''\/>\n  <\/Service>/" /usr/local/tomcat/conf/server.xml

# 移除 xml 编辑工具
# RUN apt -y autoremove --purge xmlstarlet

# 移除 xml 编辑工具

# RUN apt -y autoremove --purge xmlstarlet

构建镜像：

$ sudo podman build -t tomcat-9 .

1	$ sudo podman build -t tomcat-9 .

设置容器开机自启:

$ sudo podman stop tomcat-9

$ sudo podman rm tomcat-9

# 启动一个 tomcat 容器 8080 HTTP 访问端口 8009 AJP访问端口
# sudo podman run -d --name tomcat-9 -p 8080:8080 -p 8009:8009 -v /my/local/path:/usr/local/tomcat/webapps localhost/tomcat-9

$ sudo podman run -d --name tomcat-9 -p 8080:8080 -p 8009:8009 -v /home/data/.tomcat/webapps:/usr/local/tomcat/webapps -v /home/data/.tomcat/logs:/usr/local/tomcat/logs localhost/tomcat-9

# 查看该容器
$ sudo podman ps

# 如果需要进入容器查看执行情况，参考如下命令
# sudo podman exec -it tomcat-9 bash

# 每次都启动新容器方式创建servcie //--new参数，每次启动都删除旧容器，启动一个新容器 
$ sudo podman generate systemd --restart-policy=always -n --new -f tomcat-9

$ sudo podman stop tomcat-9

$ sudo podman rm tomcat-9

# 启动一个 tomcat 容器 8080 HTTP 访问端口 8009 AJP访问端口

# sudo podman run -d --name tomcat-9 -p 8080:8080 -p 8009:8009 -v /my/local/path:/usr/local/tomcat/webapps localhost/tomcat-9

/**

* 自义的 SM2 公钥加密、私钥解密引擎，用于替换 BouncyCastle 中的 SM2Engine 的实现,

* 可用于非 java 开发的系统之间交换数据时的公钥加密、私钥解密，完全符合 GM/T 以下两个标准：

*

* <li>《GM/T 0003.4-2012: SM2椭圆曲线公钥密钥算法：第4部分：公钥加密算法》</li>

* <li>《GM/T 0009-2012: SM2密码算法使用规范》</li>

*

*

* <li>1.加密密文默认为 C1||C3||C2, 输出内容为 ASN.1 编码。符合《GM/T 0009-2012: SM2密码算法使用规范》标准

* </li>

* <li>2.加密密文设置为 C1||C2||C3，则输出内容不是 ASN.1 编码。与《GM/T 0009-2012 ...》标准不兼容。</li>

为容器添加基于BoxDecoration的labelText (作为TextField)

TextField 有一个很好的方法来在它的 BoxDecoration 装饰上放置一个文本标签，如下：

通过以下方式：

TextField(
        onTap: onTap,
        controller: controller,
        decoration: InputDecoration(
          labelText: "XP",
          border: OutlineInputBorder(
            borderRadius: BorderRadius.circular(50.0),
          ),
        ));

TextField(

onTap: onTap,

controller: controller,

decoration: InputDecoration(

labelText: "XP",

border: OutlineInputBorder(

borderRadius: BorderRadius.circular(50.0),

));

有没有办法在 Container 的其他 BoxDecoration 上实现同样的效果？例如，我想指定标签"XP"：

        Container(
          decoration: BoxDecoration(
            borderRadius: BorderRadius.all(Radius.circular(5)),
            border: Border.all(color: color, width: 2.0),
            labelText: Text("XP"),   // No such attribute
          ),
          child: child,
        ),

Container(

decoration: BoxDecoration(

borderRadius: BorderRadius.all(Radius.circular(5)),

border: Border.all(color: color, width: 2.0),

labelText: Text("XP"), // No such attribute

child: child,

但是 Flutter 没有为 BoxDecoration 提供 labelText (仅存在于 InputDecoration )。

我们可以使用 InputDecorator 作为父对象来完成上述需求，如下：

import 'package:flutter/material.dart';

void main() {
  runApp(const MyApp());
}

class MyApp extends StatelessWidget {
  const MyApp({super.key});

  // This widget is the root of your application.
  @override
  Widget build(BuildContext context) {
    return MaterialApp(
      title: 'Flutter Demo',
      theme: ThemeData(
        primarySwatch: Colors.blue,
      ),
      home: const Home(),
      debugShowCheckedModeBanner: false,
    );
  }
}

class Home extends StatefulWidget {
  const Home({super.key});

  @override
  State<Home> createState() => _HomeState();
}

class _HomeState extends State<Home> {
  @override
  Widget build(BuildContext context) {
    return Scaffold(
      body: Center(
        child: Container(
          height: 100,
          width: 400,
          child: InputDecorator(
            decoration: InputDecoration(
                labelText: 'XP',
                border: OutlineInputBorder(
                  borderRadius: BorderRadius.circular(10),
                )),
            child: Text("Container Content"),
          ),
        ),
      ),
    );
  }
}

import 'package:flutter/material.dart';

void main() {

runApp(const MyApp());

}

class MyApp extends StatelessWidget {

const MyApp({super.key});

// This widget is the root of your application.

@override

Widget build(BuildContext context) {

return MaterialApp(

title: 'Flutter Demo',

theme: ThemeData(

primarySwatch: Colors.blue,

home: const Home(),

debugShowCheckedModeBanner: false,

);

}

class Home extends StatefulWidget {

const Home({super.key});

@override

State<Home> createState() => _HomeState();

}

class _HomeState extends State<Home> {

@override

Widget build(BuildContext context) {

return Scaffold(

body: Center(

child: Container(

height: 100,

width: 400,

child: InputDecorator(

decoration: InputDecoration(

labelText: 'XP',

border: OutlineInputBorder(

borderRadius: BorderRadius.circular(10),

)),

child: Text("Container Content"),

);

}

Flutter TextField/TextFormField垂直方向完整填充父容器高度（或者全屏显示）

正常情况下，我们使用 TextField/TextFormField 的时候，都是单行的表单或者指定行数的情况。但是有时候，我们希望能自适应父容器的高度，或者高度动态自适应变化。

那么我们应该怎么操作呢？
