一、新建工程

①操作：eclipse下File->New->Dynamic Web Project

②项目目录如下

二、Struts2配置如下

1、拷贝struts2所需的jar包到WebConten->WEB-INF->lib下

2、在src下添加action类文件和在WEB-INF下添加web页面

①在src下添加action类文件

UserAction.java类代码：

package com.jjh.ssh.web;import org.apache.struts2.convention.annotation.Namespace;import org.apache.struts2.convention.annotation.Result;import com.opensymphony.xwork2.ActionSupport;@Namespace("/user")@Result(name = "userlist", location = "userlist.jsp")public class UserAction extends ActionSupport {/** * 获取用户列表 * @return * @throws Exception */public String listUsers() throws Exception{System.out.println("-------listusers action begin-------");System.out.println("-------listusers action end-------");return "userlist";}}

②在WEB-INF下添加view->user->userlist.jsp

userlist.jsp代码：

<%@ 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>Insert title here</title></head><body>userlist for this.</body></html>

3、在src目录下添加struts.xml 和 struts.properties

①struts.xml内容

<?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></struts>

②struts.properties

#strutsstruts.action.extension=dostruts.ognl.allowStaticMethodAccess=true#struts-devstruts.devMode=truestruts.i18n.reload=true#struts-conventionstruts.convention.action.packages=com.jjhstruts.convention.package.locators=web struts.convention.result.path=/WEB-INF/view#struts-convention-devstruts.convention.classes.reload=true

4、配置web.xml

添加struts2的Filter过滤器

<?xml version="1.0" encoding="UTF-8"?><web-app xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"xmlns="http://java.sun.com/xml/ns/javaee" xmlns:web="http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd"xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_3_0.xsd"id="WebApp_ID" version="3.0"><display-name>SSHFW</display-name><!-- struts2过滤器 --><filter><filter-name>struts2</filter-name><filter-class>org.apache.struts2.dispatcher.ng.filter.StrutsPrepareAndExecuteFilter</filter-class></filter><!-- 过滤器链 --><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>

三、部署到tomcat，运行。

在浏览器中输入http://localhost:8080/SSHFW/user/user!listUsers.do
请求结果显示如下：
