I was reading that deleting detached entity will cause IllegalArgumentExcetpion, the entity should be managed to be removed. However , I'm using spring JPA repository interface and the delete is working on a detached entity , I have created new entity with the ID I want to delete and I got no exception. is there any document says we can delete detached entity in spring jpa ? I couldn't find official document.

Answer 1

在可以使用repository.delete（entity）之前，应调用repository.find（entityID）来防止“分离的实体异常”。

Answer 2

Every entity has id and you can delete deatached entity by id like

 @Modifying @Query("delete from OwnEntity e where e.id = :id")
 Long deleteById(@Param("id") Long id);
