EntityManager.detach介绍

[英]Remove the given entity from the persistence context, causing a managed entity to become detached. Unflushed changes made to the entity if any (including removal of the entity), will not be synchronized to the database. Entities which previously referenced the detached entity will continue to reference it.
[中]从持久性上下文中删除给定实体，导致托管实体分离。对实体所做的未刷新更改（如果有）（包括删除实体）将不会同步到数据库。先前引用分离实体的实体将继续引用它。
