默默的点滴

参考 http://blog.csdn.net/yuguiyang1990/article/details/8796410

1.新建Maven项目

1.1 File -> New -> Other

1.2 选择Maven Project ，单击Next

1.3 保持默认即可，单击Next

1.4 选择Archetype为 web app，单击Next

1.5 输入一些必要信息，单击Finish

1.6 项目结构如下图：

或者如下图

在Mac下面的Eclipse Kepler中目录的位置有所变化

2.配置项目（某些修改实际工作中用不到，以下仅供参考）

现在开始修改一些配置

2.1 在项目上右键单击，添加Source Folder

Maven的项目有一些约定：src/main/java , src/main/resources , src/test/java , src/test/resources .那么，添加这些文件夹：（注意，创建文件夹有可能失败，比如Kepler 上面，此时，到目录下面直接创建文件夹然后刷新Eclipse项目就可以了）

输入Source Folder 的名字

创建完之后的目录结构：

2.2 修改Build Path 配置

在项目上，右键单击，选择 Build Path ->Configure Build Path

选择 Source标签，会显示4个Source Folder ，修改他们的 OutPut folder ：

双击每个文件夹的Output folder，选择路径

src/main/java，src/main/resources，选择target /classes;
src/test/java ，src/test/resources, 选择target/test-classes;

修改完成后如下图所示：

修改JDK版本：选择 libraries 标签，选中JRE library，单击Edit按钮

选择系统默认的就可以了，单击 Finish 按钮：

最后，单击OK即可：

完成后，项目结构如下图：

2.3 将项目转换为Dynamic Web Project

在项目上右键单击，选择 Properties：

在左侧选择 Project Facets,单击右侧的 ”Convert faceted from “链接:

修改Java为你当前项目的JDK，并添加Dynamic Web Module ，最后单击”Further Configuration available“ 链接：

修改Content directory 为 src/main/webapp ,单击OK:

在一次单击OK，完成操作：

2.4 设置部署程序集(Web Deployment Assembly)

在项目上右键单击，选择Properties，在左侧选择Deployment Assembly

此处列表是，部署项目时，文件发布的路径。
1，我们删除test的两项，因为test是测试使用，并不需要部署。
2，设置将Maven的jar包发布到lib下。
Add -> Java Build Path Entries -> Maven Dependencies -> Finish
设置完成效果图

单击OK

完成后，项目结构如下图所示：

就这样，使用Maven构建的一个Web项目就完成了。

I'm working on my usual projects on Eclipse, it'a a J2EE app, made with Spring, Hibernate and so on. I'm using tomcat7 for this (no particular reason, I don't exploit any new feature, I just wanted to try that). Every time I debug my application, it happens that eclipse debugger pops out like it has reached a breakpoint, but it is not the case, in fact it stops on a Java Source File that is ThreadPoolExecutor. There is no stack trace on the console, it just stops. Then if I click on resume it goes on and the app works perfectly. This is what shows in the debugger window:

Daemon Thread ["http-bio-8080"-exec-2] (Suspended (exception RuntimeException))
ThreadPoolExecutor$Worker.run() line: 912
TaskThread(Thread).run() line: 619

I really can't explain this, because I'm not using ThreadPoolExecutor at all. Must be something from Tomcat, Hibernate or spring. It's very annoying because I always have to resume during debugging.

Any clues?

The posted stack trace indicates that a RuntimeException was encountered in a Daemon thread. This is typically uncaught at runtime, unless the original developer caught and handled the exception.

Typically, the debugger in Eclipse is configured to suspend execution at the location where the exception was thrown, on all uncaught exceptions. Note that the exception might be handled later, lower down in the stack frame and might not lead to the thread being terminated. This would be cause of the behavior observed.

Configuring the behavior of Eclipse is straightforward - in the Preferences Dialog, the Debug pane under Java in the tree hierarchy, has the option titled "Suspend execution on uncaught exceptions", which can be unchecked.
