我写了一个查询来删除接口中的一些对象，扩展了JPaRepository，但是当我执行查询时，它抛出了一个异常！有人能为我解释一下吗？
查询：

public interface LimitRepository extends JpaRepository<CLimit, Long> {

  @Query("delete from CLimit l where l.trader.id =:#{#trader.id}")
  void deleteLimitsByTrader(@Param("trader") CTrader trader);

}

我得到了这个错误，可以anyne请，为我解释一下，并感谢大家：）
例外情况：

试试这个：

public interface LimitRepository extends JpaRepository<CLimit, Long> {
  @Modifying
  @Query("delete from CLimit l where l.trader.id =:#{#trader.id}")
  void deleteLimitsByTrader(@Param("trader") CTrader trader);
}

每当你试图修改db中的记录时，你必须将其标记为@Modifying，这指示Spring它可以修改现有的记录。
修改查询只能使用void或int/Integer作为返回类型，否则将抛出异常。

我也遇到了同样的问题，我尝试了@afridi的答案，据我所知，这个答案很好，但实践不好。你不应该在仓库类中使用@Transactional注解，而应该在服务（和实现）类中使用。请找到下面的答案。
LimitServiceImpl.java

import org.springframework.transaction.annotation.Transactional;
...
@Override
@Transactional
public void deleteLimitsByTrader(CTrader trader) {
// here im calling the LimitRepository interface. 
 getEntityRepository().deleteLimitsByTrader(trader);
}

LimitRepository.java

import org.springframework.data.jpa.repository.Modifying;
import org.springframework.data.jpa.repository.Query;
...
public interface LimitRepository extends JpaRepository<CLimit, Long> {

  @Modifying
  @Query("delete from CLimit l where l.trader.id =:#{#trader.id}")
  void deleteLimitsByTrader(@Param("trader") CTrader trader);

}

确保使用正确的导入。

你忘了在上面的方法中添加两个annotations。

@Transactional
@Modifying

我使用EntityManager.createQuery("your deleteStatement").executeUpdate();解决了这个问题

添加@Transactional(org.springframework.transaction.annotation.Transactional)和@Modifying(org.springframework.data.jpa.repository.Modifying)，为我解决了类似的问题

如果你正在使用repositary，那么大多数答案都可以工作。如果有人正在使用实体管理器
then use 1.Transactional 2.entitymanager.createQuery（“your deleteStatement”）.executeUpdate（）;

@Transactional
public Integer somemethod() {

entitymanager.createQuery("your deleteStatement").executeUpdate();

}
