一、 http://www.struts.apche.com 下載 Full Distribution: struts-2.0.14-all.zip
二、新建webProject:struts2
導入struts2須要的jar(下載的包中):commons-logging-1.0.4.jar、ognl-2.6.11.jar、freemarker-2.3.8.jar、struts2-core-2.0.14.jar、xwork-2.0.7.jar
三、Login.jsp以下:
<%@ page language="java" import="java.util.*" pageEncoding="utf-8"
isELIgnored="false"%>
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN">
<html>
<head>
</head>
<body>
  <center>
   <form action="login.action" method="post">
    用戶名:
    <input type="text" name="username" />
    <br>
    密碼:
    <input type="password" name="password" />
    <br>
    <input type="submit" value="提交" />
    <br>
   </form>
  </center>
</body>
</html>
四、web.xml中修改以下：
<?xml version="1.0" encoding="UTF-8"?>
  <web-app version="2.5"
  xmlns=" http://java.sun.com/xml/ns/javaee"
  xmlns:xsi=" http://www.w3.org/2001/XMLSchema-instance"
  xsi:schemaLocation=" http://java.sun.com/xml/ns/javaee
   http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd">
   <filter>
   <filter-name>struts2</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>
</web-app>
5.LoginAction以下:
package com.test.action;

public class LoginAction
{
  private String username;
  private String password;
  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;
  }

  public String execute()throws Exception
  {


   return "success";
  }
}

五、result.jsp
<%@ page language="java" import="java.util.*" pageEncoding="utf-8"
isELIgnored="false"%>
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN">
<html>
<head>
</head>
<body>
  <center>
   <br>******************************<br>
   用戶名：${requestScope.username}<br>
   密碼:${requestScope.password }<br>

   *********************************<br>
   用戶名：<%=(String)request.getAttribute("username") %><br>
   密碼:<%=(String)request.getAttribute("password") %><br>

   **********************************************<br>
   用戶名：${username}<br>
   密碼:${password }<br>
   **********************************************<br>

  </center>
</body>
</html>
六、在src下建struts.xml,以下：
<?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>
<package name="struts2" extends="struts-default">
  <action name="login" class="com.test.action.LoginAction">
   <result name="success" type="dispatcher">/result.jsp</result>
  </action>
</package>
</struts>
七、 http://localhost:8080/struts2/Login.jsp 輸入用戶名、密碼提交成功跳轉
