使用Maven构建Struts2项目

来源：互联网发布：网络打鸡血是什么意思编辑：程序博客网时间：2024/05/18 04:01

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：

[html] view plaincopy
<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：

是不是都有了，有的时候Maven可能会报错，由于网络的原因（个人认为大多是网络问题，导致下载依赖包出错），可以从上面提到的两个网站手动下载

3. 新建一个Action

[java] view plaincopy
package com.deppon.test02.action;
import com.opensymphony.xwork2.ActionSupport;
public class UserAction extends ActionSupport {
private static final long serialVersionUID = -1417237614181805435L;
private String name;
private String password;
public String getName() {
return name;
}
public void setName(String name) {
this.name = name;
}
public String getPassword() {
return password;
}
public void setPassword(String password) {
this.password = password;
}
/**
* 跳转到登录界面
* @return
*/
public String login_input() {
return SUCCESS;
}
/**
* 登录
* @return
*/
public String login() {
System.out.println("name->" + name);
System.out.println("password->" + password);
return SUCCESS;
}
}

struts.xml
