Struts2 基本配置

折腾了一天总算搞定了，太马大哈了

！

1、Myeclipse 9新建一个WEB项目，然后右键项目名称，选择Myeclipse:

2、选择：

3、添加类LoginAction：

package struts2.demo.action;

import com.opensymphony.xwork2.ActionSupport;

public class LoginAction extends ActionSupport{

public String execute() throws Exception{

if("user1".equals(username) && "password1".equals(password)){
return "yes";
}
//	System.out.println("execute!");
return "error";
}

private String username ;
private String password ;

public String getUsername() {
return username;
}

public void setUsername(String username) {
this.username = username;
}

public String getPassword() {
return password;
}

public void setPassword(String password) {
this.password = password;
}

}

4、增加struts2.xml配置：

<?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="struts" namespace="/tt" extends="struts-default">
<action name="demo" class="struts2.demo.action.LoginAction">
<result name="yes">/WEB-INF/jsp/yes.jsp</result>
<result name="error">/WEB-INF/jsp/error.jsp</result>
</action>
</package>
</struts>

5、修改index.jsp代码为：

<%@ page language="java" import="java.util.*" pageEncoding="utf-8"%>
<%@ taglib prefix="s" uri="/struts-tags"%>
<%
String path = request.getContextPath();
String basePath = request.getScheme()+"://"+request.getServerName()+":"+request.getServerPort()+path+"/";
%>
<html>
<head>
<base href="<%=basePath%>">

<title>My JSP 'index.jsp' starting page</title>
<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>

<s:form action="demo" method="post" namespace="/tt" >
用户名： <input type="text" id="username" name="username" /><br />
密码： <input type="password" id="password" name="password" /><br />
<input type="submit" value="submit" />
</s:form >

</body>
</html>

6、yes.jsp代码：

<body>
登陆成功！<br>
</body>

7、error.jsp代码：

<body>
${requestScope.username}登陆失败<br>
</body>

8、打开http://localhost:8081/Struts/：

9、输入username和pass点击提交：

10、输入user1和password1点击提交：
