1．在Myeclipse下建立新的web工程，将Struts2必需的包导入lib下

2. 修改web.xml增加Struts2的拦截器

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

<web-app version="2.4"

xmlns="http://java.sun.com/xml/ns/j2ee"

xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

xsi:schemaLocation="http://java.sun.com/xml/ns/j2ee

http://java.sun.com/xml/ns/j2ee/web-app_2_4.xsd">

<filter-name>sturts2</filter-name> <filter-class>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>index.jsp</welcome-file>

</welcome-file-list>

</web-app>

3. 增加login.jsp页面

<body>

username:<input type="text" name="name"/><br>

password:<input type="text" name="pass"/><br>

</body>

4. 增加success.jsp页面

<body>

<h1>welcome to my page...</h1><br />

</body>

5. 在src下直接创建struts.xml

<?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">WEB-INF/jsp/success.jsp</result>

<result name="input">WEB-INF/jsp/login.jsp</result>

</action>

</package>

</struts>

6. 在src 下加载 struts.properties文件

此文件是struts 各种的默认配置，可在其他项目中拷贝过来

7．在src下创建文件目录action

在action目录下创建LoginAction.java

package action;

import com.opensymphony.xwork2.ActionSupport;

public class LoginAction extends ActionSupport {

private String name;

private String pass;

public String login(){

String re = "input";

if(name.equals("gong")&&pass.equals("123")){

re = "success";

}

return re;

}

public String getName() {

return name;

}

public void setName(String name) {

this.name = name;

}

public String getPass() {

return pass;

}

public void setPass(String pass) {

this.pass = pass;

}

至此一个简单的struts2就搭建好了。
