jsp+struts2登录框架模板

一、建立一个名叫jsp_struts2的项目

二、导入jar包

如上图：jar包导入在WebContent/WEB-INF/lib下

三、建立一个LoginAction类

LoginAction类的set方法取得登录界面的登录名和登录密码

execute()方法是程序的入口

public class LoginAction {
    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;
    }


    public String execute() {
        System.out.println(username+" "+password);
        if ("123456".equals(username) && "123456".equals(password)) {
            return "SUCCESS";
        }
        return "INPUT";
    }
}

四、建立界面(登录失败返回登录界面)

1、建立登录login.jsp界面

<%@ 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>登录界面</title>
</head>
<body>
    <form action="LoginAction" method="post">
        用户名：<input type="text" name="username" /><br /> 密码：<input
            type="password" name="password" /><br /> <input type="submit"
            value="提交" />
    </form>
</body>

</html>

2、建立登录成功success.jsp界面

<%@ 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>登录成功</title>
</head>

</head>
<body>
    登录成功，欢迎你，
</body>
</html>

五、配置struts.xml

<?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>
    <package name="default" namespace="/" extends="struts-default">
        <action name="LoginAction" class="nsu.edu.student.action.LoginAction">
            <result name="SUCCESS">/success.jsp</result>
            <result name="INPUT">/login.jsp</result>
        </action>
    </package>
</struts>
