在MyEclipse下创建一个Web Project，名为Struts2_1。在项目名称上右键MyEclipse->Project Facets->Install Apache Facets(Struts2) ，则可添加struts2，会在src目录下生成 struts.xml文件。
在src目录下创建class类LoginAction.java，包路径为com.study.struts.action，代码如下：
package com.study.struts.action;
import com.opensymphony.xwork2.ActionSupport;
public class LoginAction extends ActionSupport {
private String account;
private String password;
public String execute() {
if ("abc".equals(account) && "123".equals(password)) {
return SUCCESS;
}
return ERROR;
}
public String getAccount() {
return account;
}
public void setAccount(String account) {
this.account = account;
}
public String getPassword() {
return password;
}
public void setPassword(String password) {
this.password = password;
}
}
在WebRoot下创建login.jsp,success.jsp和error.jsp
login.jsp文件如下：
<%@ page language="java" import="java.util.*" pageEncoding="UTF-8"%>
<%@ taglib uri="/struts-tags" prefix="struts" %>
<%
String path = request.getContextPath();
String basePath = request.getScheme()+"://"+request.getServerName()+":"+request.getServerPort()+path+"/";
%>
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN">
<html>
<head>
<base href="<%=basePath%>">
<title>My JSP 'login.jsp' starting page</title>
<%-- <struts:head theme="ajax" /> --%>
<meta http-equiv="pragma" content="no-cache">
<meta http-equiv="cache-control" content="no-cache">
<meta http-equiv="expires" content="0">
<meta http-equiv="keywords" content="keyword1,keyword2,keyword3">
<meta http-equiv="description" content="This is my page">
<!--
<link rel="stylesheet" type="text/css" href="styles.css">
-->
</head>
<body>
<struts:form action="loginPerson">
<struts:label value="登录系统"/>
<struts:textfield name="account" label="账号"/>
<struts:password name="password" label="密码"/>
<struts:submit value="登陆"/>
</struts:form>
</body>
</html>
success.jsp 和error.jsp分别显示登陆成功和登陆失败
struts.xml文件如下：
<?xml version="1.0" encoding="UTF-8" ?>
<!DOCTYPE struts PUBLIC "-//Apache Software Foundation//DTD Struts Configuration 2.1//EN" "http://struts.apache.org/dtds/struts-2.1.dtd">
<struts>
<package name="main" extends="struts-default">
<global-results>
<result name="login">/login.jsp</result>
</global-results>
<action name="loginPerson" class="com.study.struts.action.LoginAction">
<result name="success">/welcome.jsp</result>
<result name="error">/error.jsp</result>
</action>
</package>
</struts>
web.xml文件如下：
<?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" 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>Struts_1</display-name>
<welcome-file-list>
<welcome-file>login.jsp</welcome-file>
</welcome-file-list>
<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> <!-- 截获所有的url -->
</filter-mapping>
</web-app>启动tomcat服务器，并部署struts2_1应用，就可以在浏览器输入http://localhost:8080/Struts_1访问，首先会进入登录页面，登陆成功则跳转到success.jsp页面显示欢迎，失败则跳转到error.jsp页面，显示用户名或密码错误。
