spring-jpa通过自定义sql执行修改碰到的问题

@Query("update AdminUser set username=:#{#adminUser.username},password=:#{#adminUser.password} where id=:#{#adminUser.id}") int updateInfoById(@Param("adminUser") AdminUser adminUser); 否则执行会报错错误信息如下，提示不支持修改操作

org.springframework.dao.InvalidDataAccessApiUsageException: org.hibernate.hql.internal.QueryExecutionRequestException: Not supported for DML operations [update com.leimo.module.adminuser.entity.AdminUser set username=:__$synthetic$__1,password=:__$synthetic$__2,updateTime=:__$synthetic$__3 where id=:__$synthetic$__4]; nested exception is java.lang.IllegalStateException: org.hibernate.hql.internal.QueryExecutionRequestException: Not supported for DML operations [update com.leimo.module.adminuser.entity.AdminUser set username=:__$synthetic$__1,password=:__$synthetic$__2,updateTime=:__$synthetic$__3 where id=:__$synthetic$__4]

at org.springframework.orm.jpa.AbstractEntityManagerFactoryBean.translateExceptionIfPossible(AbstractEntityManagerFactoryBean.java:527) ~[spring-orm-5.1.6.RELEASE.jar:5.1.6.RELEASE]

只是添加了 @Modifying 注解在执行修改操作的时候仍然会报错，提示在进行删除和修改的时候需要给方法加上事务

org.springframework.dao.InvalidDataAccessApiUsageException: Executing an update/delete query; nested exception is javax.persistence.TransactionRequiredException: Executing an update/delete query
at org.springframework.orm.jpa.EntityManagerFactoryUtils.convertJpaAccessExceptionIfPossible(EntityManagerFactoryUtils.java:402) ~[spring-orm-5.1.6.RELEASE.jar:5.1.6.RELEASE]

at org.springframework.orm.jpa.AbstractEntityManagerFactoryBean.translateExceptionIfPossible(AbstractEntityManagerFactoryBean.java:527) ~[spring-orm-5.1.6.RELEASE.jar:5.1.6.RELEASE]

在可以直接在Repository的修改接口上添加 @org.springframework.transaction.annotation.Transactional 注解就可以正常执行修改语句了，或者在调用改接口的方法上添加 @Transactional 事务注解即可

  @Transactional
  @Modifying
  @Query("update AdminUser set username=:#{#adminUser.username},password=:#{#adminUser.password} where id=:#{#adminUser.id}")
  int updateInfoById(@Param("adminUser") AdminUser adminUser);
