一、Struts下载地址
http://struts.apache.org/download.cgi
二、导入包、配置Web.xml和struts.xml
在下载的包中从示例中找到一些包就可以
struts2-2.3.4.1-all\struts-2.3.4.1\apps\struts2-blank\WEB-INF\lib
在Web.xml在加入
<filter>
<filter-name>struts2</filter-name>
<filter-class>org.apache.struts2.dispatcher.ng.filter.StrutsPrepareAndExecuteFilter</filter-class>
</filter> <filter-mapping>
<filter-name>struts2</filter-name>
<url-pattern>/*</url-pattern>
</filter-mapping>
struts.xml可以在struts2-2.3.4.1-all\struts-2.3.4.1\apps\struts2-blank\WEB-INF\classes下找到示例更改即可
<?xml version="1.0" encoding="UTF-8" ?>
<!DOCTYPE struts PUBLIC
"-//Apache Software Foundation//DTD Struts Configuration 2.3//EN"
"http://struts.apache.org/dtds/struts-2.3.dtd"><struts>

-->
<!-- Add packages here -->
<constant name="struts.devMode" value="true" />
<package name="default" namespace="/" extends="struts-default"> <action name="hello" class="com.pb.web.action.HelloAction3">
<result>
/helloStruts.jsp
</result>
</action>
</package>
</struts>
三、实现
action
package com.pb.web.action;import com.opensymphony.xwork2.ActionSupport;
/*
* 第三种 继承 ActionSupport类它是Action的实现类
*/
public class HelloAction3 extends ActionSupport { /**
*
*/
private static final long serialVersionUID = 1L; @Override
public String execute() throws Exception {
// TODO Auto-generated method stub
return "success";
}}
页面
helloStruts.jsp
<%@ page language="java" contentType="text/html; charset=UTF-8"
pageEncoding="UTF-8"%>
<!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd">
<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=UTF-8">
<title>HelloStruts</title>
</head>
<body>
<h1 align="center">Hello Struts!</h1>
</body>
</html>
在地址栏中输入http://localhost:8080/StrutsDemo1/hello.action
以hello.action访问就可以跳到helloStruts.jsp页面
