read lock

您好 jpa - spec如何实现read lock呢？

[Wen Hao]

这个本就是Spring Data JPA的功能吧。

public interface SimpleRepository extends JpaRepository<Simple, Long>, JpaSpecificationExecutor<Simple> {
     @Lock(LockModeType.READ)
     public Optional<Simple> findById(Long id);
}

嗯，可是findAll(Specification s)怎么设置呢？

[Wen Hao]

public interface SimpleRepository extends JpaRepository<Simple, Long>, JpaSpecificationExecutor<Simple> {
     @Lock(LockModeType.READ)
     public Page<Simple> findAll(Specification s);
}
