Springboot 扫描mapper接口的2种操作

@Mapper
 
(将包中的所有接口都标注为DAO层接口)
public interface UserMapper {
  UserInfo getUserInfo(@Param("userId") String userId);
}

@SpringBootApplication
@MapperScan(basePackages = "com.xiami.springboot.sbootdemo.mapper")
public class SbootdemoApplication {
 
  @Autowired
  private ApplicationArguments applicationArguments;
 
  public static void main(String[] args) {
    SpringApplication.run(SbootdemoApplication.class, args);
  }
