问题 I have a Spring data repository: @Repository interface SomeRepository extends CrudRepository<Entity, Long> { Stream<Entity> streamBySmth(String userId); } I am calling that method in some Spring bean: @Scheduled(fixedRate = 10000) private void someMethod(){ someRepository.streamBySmth("smth").forEach(this::callSomeMethod); } I am using MySQL database.
