Struts2--Dynamic Result动态结果集

${r} : 表示配置文件xml可以读取action的valuestack的内容

 

1. jsp显示文件:

<body>
动态结果
一定不要忘了为动态结果的保存值设置set get方法
<ol>
	<li><a href="user/user?type=1">返回success</a></li>
	<li><a href="user/user?type=2">返回error</a></li>
</ol>	
</body>

2. 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>
    <constant name="struts.devMode" value="true" />
    <package name="user" namespace="/user" extends="struts-default">
    	
	    <action name="user" class="com.bjsxt.struts2.user.action.UserAction">
	    	<result>${r}</result>
	    </action>	    
    </package>
    	
</struts>

3. action:

package com.bjsxt.struts2.user.action;

import com.opensymphony.xwork2.ActionSupport;

public class UserAction extends ActionSupport {
	private int type;	
	private String r;
	public String getR() {
		return r;
	}
	public void setR(String r) {
		this.r = r;
	}
	public int getType() {
		return type;
	}
	public void setType(int type) {
		this.type = type;
	}
	@Override
	public String execute() throws Exception {
		if(type == 1) r="/user_success.jsp";
		else if (type == 2) r="/user_error.jsp";
		return "success";
	}

}
