У меня есть две запланированные задачи, которые выполняются через разные промежутки времени.Первая задача должна запускаться каждые 5 секунд, а вторая задача - каждые 10 минут.
@EnableScheduling
public class ScheduledTask {
@Autowired
private taskService taskService;
@Scheduled(every 5 second)
public void scheduleTaskA() {
taskService.taskA()
}
@Scheduled(every 10 minute)
public void scheduleTaskB() {
taskService.taskB()
}
}
public class TaskServiceImpl implements TaskService {
@PersistenceContext
private EntityManager entityManager;
void taskA(){
StoredProcedureQuery query = entityManager.createStoredProcedureQuery("callStoreProcedure1");
if(query.execute())
query.getSingleResult();
}
void taskB(){
StoredProcedureQuery query = entityManager.createStoredProcedureQuery("callStoreProcedure2");
if(query.execute())
query.getSingleResult();
}
}
Каждый раз, когда запускается вторая задача, выдается java.lang.IllegalStateException: Session/EntityManager is closed
.Похоже, первой задачей является закрытие entityManager.Как можно избежать этого без изменения аннотации @PersistenceContext?
