sping data jpa異常 :org.springframework.dao.InvalidDataAccessApiUsageException

項目使用了springBoot +spring data jpa
在執行一個update(jpql語句)的時候報了異常:

org.springframework.dao.InvalidDataAccessApiUsageException: org.hibernate.hql.internal.QueryExecutionRequestException: Not supported for DML operations [update wonders.shgjj.gddq.common.entity.GddqLinkDebtBreaksEntity set status = ?1 where zjhm = ?2 and dkzh = ?3]; nested exception is java.lang.IllegalStateException: org.hibernate.hql.internal.QueryExecutionRequestException: Not supported for DML operations [update wonders.shgjj.gddq.common.entity.GddqLinkDebtBreaksEntity set status = ?1 where zjhm = ?2 and dkzh = ?3]

看這個異常也比較少見 , 最後發現是粗心少加了一個註解 @Modifying 如下:

以前都是加的,但是這次意外忘加了,發現了這個異常,剛好認識一下異常.

spring data jpa @Modifying註解

• 在@Query註解中編寫JPQL實現DELETE和UPDATE操作的時候必須加上@modifying註解，以通知Spring Data 這是一個DELETE或UPDATE操作。
• 注意JPQL不支持INSERT操作。
