1.首先为了能直观地在jsp页面体现session的内容，我使用了jstl表达式，首先在pom.xml中引入jstl的依赖
<!-- jstl所需要的依赖 --> <dependency> <groupId>jstl</groupId> <artifactId>jstl</artifactId> <version>1.2</version> </dependency>
2.编写登录界面以及登录成功界面
<%@ page contentType="text/html; charset=utf-8" pageEncoding="utf-8"%> <!DOCTYPE html > <html> <head> <meta charset="utf-8"> <title>用户登录</title> </head> <body> <form action="login" method="post"> <input type="text" name="uname" /><br/><br/> <input type="password" name="pwd" /><br/><br/> <input type="submit" value="登录"><br/><br/> </form> </body> </html>
登录成功界面
<%@ page contentType="text/html; charset=utf-8" pageEncoding="utf-8"%> <%@taglib uri="http://java.sun.com/jsp/jstl/core" prefix="c" %><!-- 引入jstl库 --> <!DOCTYPE html > <html> <head> <meta charset="utf-8"> <title>成功</title> </head> <body> <h1>${sessionScope.user.uname }登录成功!!!</h1> <h2>欢迎您,${sessionScope.uname }</h2> </body> </html>
3.编写请求处理类以及实体类
package com.yc.entity; public class User { private String uname; private String pwd; public String getUname() { return uname; } public void setUname(String uname) { this.uname = uname; } public String getPwd() { return pwd; } public void setPwd(String pwd) { this.pwd = pwd; } public String toString() { return "User [uname=" + uname + ", pwd=" + pwd + "]"; } }
请求处理类
package com.yc.controllers; import org.springframework.stereotype.Controller; import org.springframework.ui.ModelMap; import org.springframework.web.bind.annotation.ModelAttribute; import org.springframework.web.bind.annotation.RequestMapping; import org.springframework.web.bind.annotation.SessionAttributes; import com.yc.entity.User; @Controller @SessionAttributes({"user","uname"}) public class LoginController { @RequestMapping("/login") public String login(User user,ModelMap map) { //user会自己注入session中 //将uname放入session作用域中，这样转发页面也可以取到这个数据。 map.addAttribute("uname", user.getUname()); return "loginSuccess"; } }
4.运行测试
OK,到现在我们利用session实现的用户登录已经可以了
