Property-Driven

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"><struts>    <package name="default" namespace="/" extends="struts-default">        <default-action-ref name="index" />        <action name="index" class="action.UserAction">            <result name="success">success.jsp</result>        </action>    </package></struts>

UserAction

package action;import com.opensymphony.xwork2.Action;public class UserAction implements Action{private String username;private String password;public UserAction() {super();}private UserAction(String username, String password) {super();this.username = username;this.password = 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;}@Overridepublic String execute() throws Exception {System.out.println("初始化成功！"); return "success";}public String test(){System.out.println(username+"====="+password);return "success";}}

index.jsp

<form action="demo!test" method="get">用户名：<input name="username" />密码：<input name="password" /><input type="submit" value="提交" /></form><!--如果页面是user.username,user.password那么只要在action里面放一个user和user的set、get方法就够了，user被自动填满。-->

访问index后，在struts.xml中查找，后来数据在UserAction里输出，然后跳到success.jsp页面（网页上就说成功了，so在此省略）。
