1. 新建一个基本的Web项目
这和前面讲的是一样的，可以参考前面的博客
2. 添加Struts2依赖
这里主需要在pom.xml中添加一个struts-core的依赖即可：

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 |
<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/maven-v4_0_0.xsd"> <modelVersion>4.0.0</modelVersion> <groupId>com.deppon.demo</groupId> <artifactId>test02</artifactId> <packaging>war</packaging> <version>0.0.1-SNAPSHOT</version> <name>test02 Maven Webapp</name> <url>http://maven.apache.org</url> <!-- 属性配置 --> <properties> <project.build.sourceEncoding>UTF-8</project.build.sourceEncoding> </properties> <dependencies> <!-- 添加JUnit --> <dependency> <groupId>junit</groupId> <artifactId>junit</artifactId> <version>3.8.1</version> <scope>test</scope> </dependency> <!-- Struts2 依赖 --> <dependency> <groupId>org.apache.struts</groupId> <artifactId>struts2-core</artifactId> <version>2.3.1</version> </dependency> </dependencies> <build> <finalName>test02</finalName> </build> </project> |
之后，Maven会自动从网上下载struts2需要的其他依赖包，可以看一下这里：
3. 新建一个Action
