基于SpringBoot和Vue3的博客平台的用户注册与登录功能实现

spring:
  datasource:
    url: jdbc:mysql://localhost:3306/your_database?useSSL=false&allowPublicKeyRetrieval=true&serverTimezone=UTC
    username: your_username
    password: your_password
  mybatis:
    mapper-locations: classpath:mapper/*.xml
    type-aliases-package: com.example.demo.entity
server:
  port: 8080

public class User {
    private Integer id;
    private String username;
    private String password;
 
    // Getter and Setter methods
}

@Mapper
public interface UserMapper {
    User findByUsername(String username);
    void insert(User user);
}

public interface UserService {
    User findByUsername(String username);
    void register(User user);
}
 
@Service
public class UserServiceImpl implements UserService {
    @Autowired
    private UserMapper userMapper;
 
    @Override
    public User findByUsername(String username) {
        return userMapper.findByUsername(username);
    }
 
    @Override
    public void register(User user) {
        userMapper.insert(user);
    }
}
