第六章 用实体接收参

创建实体类User

package com.xbb.springboot.tutorial.entity;

import java.sql.Date;

public class User {
    private String id;
    private String username;
    private String password;
    private Date birthday;

    public String getId() {
        return id;
    }

    public void setId(String id) {
        this.id = id;
    }

    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 Date getBirthday() {
        return birthday;
    }

    public void setBirthday(Date birthday) {
        this.birthday = birthday;
    }

}

修改LoginController中login方法用User实体接收参数

@RequestMapping("login")
    public ModelAndView login(HttpServletRequest request, User user) {
        ModelAndView mav = new ModelAndView();
        
        if ("admin".equals(user.getUsername()) && "666666".equals(user.getPassword())) {
            request.getSession().setAttribute("user", user);
            mav.setViewName("redirect:/view/index");//客户端跳转
            return mav;
        } else {
            mav.addObject("errorMsg", "用户名或密码有误");
            mav.setViewName("login");//服务器跳转
            return mav;
        }
    }

修改index.html获取用户信息

<!DOCTYPE html>
<html>
<head>
<meta charset="UTF-8">
<title>Insert title here</title>
</head>
<body>
${user.username}<br/>
${user.password}
</body>
</html>

修改LoginInterceptor中preHandle方法

@Override
    public boolean preHandle(HttpServletRequest request, HttpServletResponse response, Object handler)
            throws Exception {
       User user = (User)request.getSession().getAttribute("user");
       if (user == null) {
           response.sendRedirect("/view/login");
           return false;
       }
       return true;
    }

重新登录

http://localhost:8080/view/login
