3、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.action.extension" value="action,do,webwork" />
 <package name="default"  namespace="/" extends = "struts-default">

     class="com.dms.base.strust.VerySimpleAction"
     method="hello" >
     <result name="success">/bLogin.jsp</result>
     </action>
 </package>
</struts>

 

 

4、VerySimpleAction

package com.dms.base.strust;

public class VerySimpleAction {

 public String hello(){
  return "success";
 }
 }

 

5、页面

<%
String path = request.getContextPath();
String basePath = request.getScheme()+"://"+request.getServerName()+":"+request.getServerPort()+path+"/";
%>

<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN">
