Question

我正在尝试执行一个必须从子选择中删除项目的查询。

环境：

Wildfly 8.2
Spring Framework 4.1.6
Spring Data 1.8.0
Hibernate 4.3.10
MySQL 5

这是存储库：

public interface MySecondEntityRepository extends JpaRepository<MySecondEntity, UUID> {
    @Modifying
    @Transactional(propagation = Propagation.REQUIRES_NEW)
    @Query("DELETE FROM MySecondEntity e WHERE e.uuid IN ("
             + "SELECT e2.uuid "
             + "FROM MySecondEntity e2, MyEntity e1 "
             + "WHERE e2.entityUUID = e1.uuid "
             + "AND e1.uuid = :uuid "
             + "AND e1.*** = ..."
             + "AND e1.*** = ..."
         + ")")
    public void deleteByEntityUUID(@Param("uuid") UUID entityUUID, ...);
}

以下是事务管理器的XML定义：

<bean id="transactionManager" class="org.springframework.orm.jpa.JpaTransactionManager">
    <property name="entityManagerFactory" ref="entityManagerFactory" />
</bean>

其中entityManagerFactory是LocalContainerEntityManagerFactoryBean。

我正在使用它们而不是依赖提供者。

在日志中，我可以看到：

SQL | insert into HT_my_entity select ...
SQL | delete from my_entity where uuid IN (select uuid FROM HT_my_entity);

当我手动执行select ...时，我会删除正确的uuids。但是当spring / hibernate执行它们时，即使使用Propagation.REQUIRES_NEW，事务也不会提交。没有例外。

我尝试了什么：

Propagation.REQUIRED和Propagation.REQUIRES_NEW
.flush()
打开子查询以进行测试。它工作正常。
更新Spring Data / Hibernate

注意：

出于性能原因，我未在MySecondEntity中添加MyEntity。 MyEntity可以有10k + MySecondEntity。我知道我可以使用延迟提取，但实际上，实体被映射到数据传输对象，这会导致映射过程出现问题。另外，我不希望检索所有数据来删除它们。

该方法直接从@RestController。

Spring Data / JPA / Hibernate：不提交更改
