org.hibernate.HibernateException: Illegal attempt to associate a collection with two open sessions
エンティティを切り離す方法や、このアーキテクチャでセッションを閉じる方法がわかりません。助けてくれてありがとう。
CommunicationService.sendCommunications()
コード:
public void sendCommunications(HibernateMessageToSendRepository messageToSendRepository) {
Long messageId = new Long(41); //this is only for test. the idea is get a list of id and generate a thread group.
MessageSender sender = SmsSender(messageId, messageToSendRepository);
sender.start();
}
呼び出しsendCommunications
コード:
ApplicationContext appCont = new ClassPathXmlApplicationContext("appContext.xml");
ServiceLocator serviceLocator = ServiceLocator.getInstance();
HibernateMessageToSendRepository messageToSendRepository = (HibernateMessageToSendRepository) appCont.getBean("messageToSendRepository");
CommunicationService communication = serviceLocator.getCommunicationService();
communication.sendCommunications(messageToSendRepository);
SmsSender(MessageSender(スレッド)から拡張)コード:
