Struts2--Global Result全局结果集

如果有很多action,有共同的result指向, 而且属于不同的包,那么可以继承上面的包, 然后写一个<global-results>

1. jsp显示文件:

<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>
	<li><a href="user/user?type=3">返回global result</a></li>
	<li><a href="admin/admin">admin,继承user包</a></li>
</ol>

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">
     	<global-results>
    		<result name="mainpage">/main.jsp</result>
    	</global-results>
    	
    	<action name="index">
    		<result>/index.jsp</result>
    	</action>
   	    <action name="user" class="com.bjsxt.struts2.user.action.UserAction">
	    	<result>/user_success.jsp</result>
	    	<result name="error">/user_error.jsp</result>
	    </action>	    
    </package>
    
    <package name="admin" namespace="/admin" extends="user">
    	<action name="admin" class="com.bjsxt.struts2.user.action.AdminAction">
    		<result>/admin.jsp</result>
    	</action>
    </package>
</struts>

userAction.JAVA:

package com.bjsxt.struts2.user.action;

import com.opensymphony.xwork2.ActionSupport;

public class UserAction extends ActionSupport {
	private int type;
	public int getType() {
		return type;
	}
	public void setType(int type) {
		this.type = type;
	}
	@Override
	public String execute() throws Exception {
		if(type == 1) return "success";
		else if (type == 2) return "error";
		else return "mainpage";
	}
}

adminAction.java:

package com.bjsxt.struts2.user.action;

import com.opensymphony.xwork2.ActionSupport;

public class AdminAction extends ActionSupport {

	@Override
	public String execute() throws Exception {
		return "mainpage";
	}
