关于Struts2的Action的跳转方式（跳转到JSP）（跳转到Action）

success.jsp里：${name }---this is success.jsp

一、跳转到JSP

请求转发：http://localhost:8080/struts2action/testAction1!test1?name=tom

index.jsp里：<a href="testAction1!test1?name=tom">请求转发</a><br>

struts.xml里：

1 <?xml version="1.0" encoding="UTF-8" ?>
2 <!DOCTYPE struts PUBLIC "-//Apache Software Foundation//DTD Struts Configuration 2.1//EN" "http://struts.apache.org/dtds/struts-2.1.dtd">
3 <struts>
4     <package name="xsl" namespace="/" extends="struts-default">
5
6         <action name="testAction1" class="com.xsl.action.TestAction1">
7             <!--
8                 type属性不写，默认则为type="dispatcher"
9                 tyoe="redirect"表示重定向到jsp
10                 type="chain"表示请求转发至另一个action
11              -->
12             <result name="test1" type="dispatcher">/success.jsp</result>
13
14         </action>
15
16     </package>
17 </struts>

TestAction1.java里：

1 package com.xsl.action;
2
3 import com.opensymphony.xwork2.ActionSupport;
4
5 public class TestAction1 extends ActionSupport {
6     private String name;
7     public String test1(){
8         System.out.println("请求转发--action1--test1--name--"+name);//请求转发--action1--test1--name--tom 9         //request.setAttribute("name",name);
10         return "test1";
11     }
12     public String getName() {
13         return name;
14     }
15     public void setName(String name) {
16         this.name = name;
