学生管理系统带前端页面（springboot+mybatis+MySQL）_管理系统前端页面

本人负责后端，本次完成了user的查询所有和添加功能

后端代码

数据层（Dao层）

@Mapper
public interface UserDao {
    User selectByNameId(User user);  //根据username和password查询
 
    List<User> selectAll();//查询所有
 
    int addUser(User user);//添加user
 
    int deleteUser(String id);//通过工号删除(修改逻辑删除字段0为删除)
}

    <insert id="addUser">
        insert into studentsystem.tb_user values (#{id},#{name},#{college},#{tel},#{email},#{username},#{password},#{status},#{deleted})
    </insert>
    <update id="deleteUser">
        update studentsystem.tb_user set deleted = 0 where id = #{id};
    </update>
 
    <select id="selectByNameId" resultType="com.example.studentsystem.pojo.User">
        select * from studentsystem.tb_user where username = #{username} and password = #{password}
    </select>
    <select id="selectAll" resultType="com.example.studentsystem.pojo.User">
        select * from studentsystem.tb_user where deleted = 1
    </select>

业务层（Service）

@Transactional
public interface UserService {
    boolean login(User user);  //登录
 
    List<User> selectAll(); //查询所有
 
    boolean addUser(User user);//添加
 
    boolean deleteUser(String id);
}

@Service
public class UserServiceImpl implements UserService {
    @Autowired
    private UserDao userDao;
 
    @Override
    public boolean login(User user) {
        User user1 = userDao.selectByNameId(user);
        if(user1 == null){
            return false;
        }
        return user1.getDeleted() != 0 && user1.getStatus() != 0;
    }
 
    @Override
    public List<User> selectAll() {
        List<User> users = userDao.selectAll();
        return users;
    }
 
    @Override
    public boolean addUser(User user) {
        if(user == null){
            return false;
        }
        user.setStatus(1);
        user.setDeleted(1);
        int i = userDao.addUser(user);
        return i>0;
    }
 
    @Override
    public boolean deleteUser(String id) {
        int i = userDao.deleteUser(id);
        return i>0;
    }
}

表现层（Controller）

@Slf4j
@RestController
@RequestMapping("/users")
public class UserController {
    @Autowired
    private UserService userService;
 
    @PostMapping("/login")
    public Result login(@RequestBody User user) {
        boolean flag = userService.login(user);
        return new Result(flag ? Code.SUCCESS : Code.FAIL, flag);
    }
 
    @PostMapping("/selectAll")
    public Result selectAll() {
        List<User> users = userService.selectAll();
        boolean flag = !users.isEmpty();
        log.info(users.toString());
        return new Result(flag ? Code.SUCCESS : Code.FAIL,users);
    }
 
    @PostMapping("/addUser")
    public Result addUser(@RequestBody User user) {
        boolean flag = userService.addUser(user);
        return new Result(flag ? Code.SUCCESS : Code.FAIL,flag);
    }
 
    @GetMapping("/deleteUser")
    public Result deleteUser(String id){
        boolean flag = userService.deleteUser(id);
        return new Result(flag ? Code.SUCCESS : Code.FAIL,flag);
    }
}
