项目结构:



所需jar包:

       获取方法就是下载struts2的2.1.6版本压缩包,解压,获得struts-2.1.6/apps下的struts2-blank-2.1.6.war,再解压缩,获取struts2-blank-2.1.6\WEB-INF\lib下的全部jar包,这就是搭建基本的struts2框架所需要的jar包。

HelloWorld_Struts2.java源代码:

package com.struts2.helloworld_struts2;import com.opensymphony.xwork2.ActionSupport;@SuppressWarnings("serial")public class HelloWorld_Struts2 extends ActionSupport{@Overridepublic String execute() throws Exception {// TODO Auto-generated method stubSystem.out.println("This Is HelloWorld_Struts2 Page."+"\n");return SUCCESS;}}

index.jsp页面源代码:

<%@ page language="java" import="java.util.*" pageEncoding="ISO-8859-1"%><%String path = request.getContextPath();String basePath = request.getScheme()+"://"+request.getServerName()+":"+request.getServerPort()+path+"/";%><html>  <head>    <base href="<%=basePath%>">    <title>This Is Index Page</title>  </head>  <body>  <h2>This Is HelloWorld_Struts2 Index Page</h2> <br>    Welcome To    <a href="<%=basePath%>helloworld_struts2" style="text-decoration: none">HelloWorld_Struts2</a>    page.<br/>  </body></html>

HelloWorld_Struts2.jsp页面源代码:

<html><head><title>This Is HelloWorld_Struts2 Page</title></head><body><h2>This Is <span style="color: blue">HelloWorld_Struts2</span> Page.</h2><br></body></html>

web.xml配置文件源代码:

<?xml version="1.0" encoding="UTF-8"?><web-app version="2.5" xmlns="http://java.sun.com/xml/ns/javaee" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd"><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>  <welcome-file-list>    <welcome-file>index.jsp</welcome-file>  </welcome-file-list>  </web-app>

struts.xml-Struts2配置文件源代码:

<?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="default" namespace="/" extends="struts-default">        <action name="helloworld_struts2" class="com.struts2.helloworld_struts2.HelloWorld_Struts2">            <result>/HelloWorld_Struts2.jsp</result>          </action>    </package></struts>

访问路径:

http://localhost:8080/HelloWorld_Struts2/


运行结果:



点击蓝色字体,进入struts2界面:



此时控制台输出:

This Is HelloWorld_Struts2 Page.
