Question

我有下一个JPARepo代码：

public interface MyObjectRepository extends JpaRepository<MyObject, UUID> {
  @Modifying
  @Query("UPDATE MyObject obj SET obj.deleted = true WHERE obj.objectId = ?1")
  void deleteById(UUID uuid);
}

为其服务而致：

@Service
@Slf4j
@Transactional(readOnly = true)
public class MyService {
@Autowired
  private MyObjectRepository myObjectRepository;

  // some methods here

  @Transactional
  public void deleteMyObject(MyObject myObject) {
    ** first way **
    myRepository.deleteById(myObject.getMyObjectId());
    ** second way **
    myObject.setDeleted(true);
    myObjectRepository.save(myObject);
  }

  //some methods here

}

两种更新方式只执行一次。下次我调用方法时，默认情况下，删除列中的实体值为false，更新后它保持为false。但是在调试时我会逐步查看表格，我看到删除列设置为true，当我发布调试时，删除标志再次设置为false。是缓存还是不正确的注释？

我认为班级@Transactional(readOnly = true)适用于所有方法，您可以在方法级别将其更改为@Transactional(readOnly = false)。

 @Transactional(readOnly = false)
  public void deleteMyObject(MyObject myObject) {

Spring JpaRepository不会更新表
