java - Spring JpaRepository 不更新表

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);
}

及其调用的服务:

@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。下次调用方法时，删除列中的实体值默认为 false，更新后仍保持 false。但是，当在调试中时，我一步步查看表，我看到删除的列被设置为 true，当我释放调试时，删除标志再次设置为 false。是缓存还是注释不正确？

我认为类级别的@Transactional(readOnly = true)适用于所有方法，能否在方法中将其更改为@Transactional(readOnly = false)级别。

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