public class User {
    @ApiModelProperty(value = "用户Id",dataType = "int")
    private Integer userId;

3. DAO接口层

@Repository
public interface UserDao {
    //用户注册
    public int insertUser(User user);
    //根据用户名查询用户信息
    public User queryUserByName(String name);
}

5.service层

public interface UserService {
    //用户注册
    public ResultVO userRegist(String username,String password);
    //用户登录
    public ResultVO checkLogin(String username,String password);
}

6.Service实现类

@Service
@Scope("singleton")
public class UserServiceImpl implements UserService {

    @Autowired
    private UserDao userDao;

    @Transactional
    public ResultVO userRegist(String username, String password) {
        synchronized (this) {

                user.setUserRegtime(new Date());
                user.setUserModtime(new Date());
                int i = userDao.insertUser(user);
                if (i > 0) {
                    return ResultVO.success("注册成功!");
                } else {
                    return ResultVO.error("注册失败!");
                }
            } else {
                return ResultVO.error("该用户名已经被注册!");
            }
        }

    }

    @Override

7.Api接口层

@RestController
@RequestMapping("/user")
@Api(value = "提供用户添加、修改、删除及查询等相关接⼝",tags = "01.用户管理")
public class UserApi {
    @Resource
    private UserService userService;
