Question

我定义了以下存储库：

@Repository
public interface IntegrationPeriodConstraintsRepository extends CrudRepository<IntegrationPeriodConstraint, IntegrationPeriod>
{
    @Query("select case when (count(ipc) > 0) then true else false end from IntegrationPeriodConstraint ipc where ipc.m_enabled = true")
    boolean hasEnabledConstraints();

    @Modifying
    @Query("update IntegrationPeriodConstraint ipc set ipc.m_lastIntegrationTimeIntegratedData = :time where ipc.m_integrationPeriod = :integrationPeriod")
    void setLastIntegrationTimeIntegratedData( @Param("integrationPeriod") IntegrationPeriod integrationPeriod,
                                               @Param("time") DateTime lastIntegrationTime );
}

但是，似乎此setLastIntegrationTimeIntegratedData方法无效。我有一个使用嵌入式H2数据库的单元/集成测试，该数据库显示在调用之后，数据库中没有更新。

我启用了Hibernate日志记录，它显示了这个：

我觉得奇怪的是第二个参数没有记录？

这是我使用的Hibernate映射文件：

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE hibernate-mapping PUBLIC
        "-//Hibernate/Hibernate Mapping DTD//EN"
        "http://www.hibernate.org/dtd/hibernate-mapping-3.0.dtd">

        <property name="m_lastIntegrationTimeBicycleData" column="lastIntegrationTimeBicycleData" type="org.jadira.usertype.dateandtime.joda.PersistentDateTime"/>
    </class>

</hibernate-mapping>

Answer 1

这似乎是另一种方式

名称= “m_lastIntegrationTimeIntegratedData” 柱= “lastIntegrationTimeIntegratedData”

Column是数据库中列的名称，name是实体中的属性。

Answer 2

用@Modifying（clearAutomatically = true）替换@Modifying应该可以。

Answer 3

您可以在Spring Data JPA中进行检查（在“修改查询”下）：
https://docs.spring.io/spring-data/jpa/docs/current/reference/html/#reference

这：

https://www.baeldung.com/spring-data-jpa-modifying-annotation

这对我有用：

@Transactional
@Modifying(flushAutomatically = true)
@Query("UPDATE User a SET a.activeStatus=?1 WHERE a.username=?2")
int setUserActiveStatusFlag(int activeStatus,String username);

对于我使用的@Transactional：javax.transaction.Transactional

通过Spring Data中的@Modifying @Query更新无效
