SSM框架之实现登录模块

这是自己做的一个SSM框架的登录模块。
开发工具：IDEA2020，JDK1.8，navicat15
运行结果:
附上自己的天翼云盘链接 ： https://cloud.189.cn/t/VVbu637nYN73

首先是数据库图片:

接下来是项目结构:


最后是建表语句：

```sql
SET NAMES utf8mb4;
SET FOREIGN_KEY_CHECKS = 0;

-- ----------------------------
-- Table structure for user
-- ----------------------------
DROP TABLE IF EXISTS `user`;
CREATE TABLE `user`  (
  `id` int(11) NOT NULL AUTO_INCREMENT,
  `name` varchar(255) CHARACTER SET utf8 COLLATE utf8_general_ci NOT NULL,
  `password` varchar(255) CHARACTER SET utf8 COLLATE utf8_general_ci NULL DEFAULT NULL,
  `sex` varchar(32) CHARACTER SET utf8 COLLATE utf8_general_ci NULL DEFAULT '男',
  `telephone` varchar(255) CHARACTER SET utf8 COLLATE utf8_general_ci NULL DEFAULT NULL,
  `address` varchar(255) CHARACTER SET utf8 COLLATE utf8_general_ci NULL DEFAULT NULL,
  `email` varchar(255) CHARACTER SET utf8 COLLATE utf8_general_ci NULL DEFAULT NULL,
  `PUID` int(11) NULL DEFAULT NULL,
  PRIMARY KEY (`id`) USING BTREE
) ENGINE = InnoDB AUTO_INCREMENT = 12 CHARACTER SET = utf8 COLLATE = utf8_general_ci ROW_FORMAT = Dynamic;

-- ----------------------------
-- Records of user
-- ----------------------------
INSERT INTO `user` VALUES (1, 'Tom', '123', '男', '13323390789', '福建厦门', '[email protected]', 10);
INSERT INTO `user` VALUES (2, 'targer', '123456', '男', '14777542', '福建泉州', '123456@163', 10);
INSERT INTO `user` VALUES (3, 'haha', '123456', '女', '17120466', '福建广东', '147124@163', 10);
INSERT INTO `user` VALUES (4, 'shun', '1234', '男', '147484', '福建漳州', '123456@163', 20);
INSERT INTO `user` VALUES (7, 'cat', '123456', '男', '17120311', '福建南宁', '[email protected]', 20);

INSERT INTO `user` VALUES (9, 'admin', '123456', '男', NULL, NULL, NULL, NULL);
INSERT INTO `user` VALUES (11, '宝石', '123456', '男', '12345', '北京', '[email protected]', 30);

SET FOREIGN_KEY_CHECKS = 1;

Mapper.xml
xml这边还有一部分的Curd没有写完，但是登录的没啥问题的

<?xml version="1.0" encoding="UTF-8" ?>
<!DOCTYPE mapper PUBLIC "-//mybatis.org//DTD Config 3.0//EN"
        "http://mybatis.org/dtd/mybatis-3-mapper.dtd">
<mapper namespace="cn.fvti.Study.Dao.UserMapper">
    <!--查询所有用户-->
    <select id="findAllUser" resultType="cn.fvti.Study.Bean.User">
        select * from ssm.user;
    </select>


    <select id="findUserByID" resultType="cn.fvti.Study.Bean.User">

    </select>


    <select id="findLogin" resultType="cn.fvti.Study.Bean.User" parameterType="java.lang.String">
        select * from ssm.user where name = #{param1} and password =#{param2}
    </select>




    <insert id="insertUser" parameterType="cn.fvti.Study.Bean.User">

    </insert>




    <!--通过id删除用户-->
    <delete id="deleteUser" parameterType="int" >
        delete  from ssm.user where id =#{id};
    </delete>
</mapper>

User类

package cn.fvti.Study.Bean;


import lombok.AllArgsConstructor;
import lombok.Data;
import lombok.NoArgsConstructor;

@Data
@AllArgsConstructor
@NoArgsConstructor
public class User {

    private Integer id;
    private String name;
    private String password;
    private String sex;
    private String address;
    private String telephone;
    private String email;
    private Integer PUID;

}

Mapper接口

package cn.fvti.Study.Dao;


import cn.fvti.Study.Bean.User;
import org.springframework.stereotype.Repository;

import java.util.List;


@Repository
public interface UserMapper {
    // 查询所有
    List<User>findAllUser();

    // 通过ID查询用户
    User findUserByID(Integer id);


    // 注册用户
    int insertUser(User user);


    // 通过id删除用户
    User deleteUser(Integer id);



    // 登录用户
    User findLogin(String name,String password);
}

多叨叨一句

Mapper接口这边是传入两个参数，之前在网上找的时候，有得就传入一个参数，搞得自己踩了很多坑

Service接口

package cn.fvti.Study.Service;

import cn.fvti.Study.Bean.User;

import java.util.List;



public interface UserService {


    // 查询所有
    List<User> findAllUser();

    // 通过ID查询用户
    User findUserByID(Integer id);


    // 注册用户
    int insertUser(User user);


    // 登录用户
    boolean findLogin(String name,String password);
}

Service接口的实现类

package cn.fvti.Study.Service.Impl;

import cn.fvti.Study.Bean.User;
import cn.fvti.Study.Dao.UserMapper;
import cn.fvti.Study.Service.UserService;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Service;

import java.util.List;


@Service
public class UserServiceImpl  implements UserService {

    @Autowired
    private UserMapper mapper;


    @Override
    public List<User> findAllUser() {

        return mapper.findAllUser();
    }

    @Override
    public User findUserByID(Integer id) {

        return mapper.findUserByID(id);
    }

    @Override
    public int insertUser(User user) {

        return insertUser(user);
    }

    @Override
    public boolean findLogin(String name,String password) {
        System.out.println("输入的账号：" + name);
        System.out.println("输入的密码：" + password);
        User login = mapper.findLogin(name,password);
        if (login != null) {
            if (login.getName().equals(name) && login.getPassword().equals(password))
                return true;
            }

            return false;
        }
    }

最后一步:控制器

package cn.fvti.Study.Controller;


import cn.fvti.Study.Bean.User;
import cn.fvti.Study.Service.UserService;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.ui.Model;
import org.springframework.web.bind.annotation.*;
import org.springframework.web.servlet.ModelAndView;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
import javax.servlet.http.HttpSession;
import java.io.UnsupportedEncodingException;
import java.util.List;


@RestController
@RequestMapping("/user")
public class UserController {


    @Autowired
    private UserService service;

    @RequestMapping("/login")
    public ModelAndView login(User user, Model model, HttpServletRequest request, HttpSession session,HttpServletResponse response) {
        List<User> allUser = service.findAllUser();
        allUser.forEach(tem->{
            System.out.println(tem);
        });
        response.setCharacterEncoding("utf-8");
        model.addAttribute("AllUser", allUser);
        request.setAttribute("AllUser", allUser);
        ModelAndView mv = new ModelAndView();
        ModelAndView mv1 = new ModelAndView();
        mv1.setViewName("welcome");
        mv.setViewName("Error");
        boolean login = service.findLogin(user.getName(),user.getPassword());
        if (login) {
            session.setAttribute("user", user);
            return mv1;
        } else {
            mv.addObject("msg", "账号密码错误，请重新登录");
            return mv;
        }
    }
}

以上就是自己做的SSM登录验证的模块。
