这是配置

 <bean id="ofmTransactionManager" class="org.springframework.orm.jpa.JpaTransactionManager">
      <property name="entityManagerFactory" ref="ofmEntityManagerFactory" />
 </bean>
 <tx:annotation-driven mode="aspectj" transaction-manager="ofmTransactionManager" />
 <context:annotation-config/> 
 <context:component-scan base-package="com.xxx.dao"/>

存储库代码

@Modifying
@Query(value = "DELETE FROM ObjectName m\n" +
        "WHERE m.createdAt < :date")
void deleteOlderThan(@Param("date")Date date);

代码的使用

@Transactional
private void purgeRepo(MetricRepository repo, Integer days) {
    LocalDate date = new LocalDate().minusDays(days);
    repo.deleteOlderThan(date.toDate());
}

Answer 1

我将@Transactional移动到了存储库代码，这很有效。
