spring4+hHibernate5 项目使用多线程时单个线程无法获取session问题

1.事务需要由spring管理

<prop key="hibernate.current_session_context_class">
    org.springframework.orm.hibernate5.SpringSessionContext
</prop>

2.在业务service注入sessionFactory

@Resource(name="sessionFactory")
private SessionFactory sessionFactory;

3.service方法添加事务注解
单个线程{

//绑定session到当前线程
boolean participate = serviceImpl.bindHibernateSessionToThread(sessionFactory);
//业务逻辑...

//关闭session

serviceImpl.closeHibernateSessionFromThread(participate, sessionFactory);

}

// 绑定Session到新的线程方法
public static boolean bindHibernateSessionToThread(SessionFactory sessionFactory) {
   if (TransactionSynchronizationManager.hasResource(sessionFactory)) {
      // Do not modify the Session: just set the participate flag.
      return true;
   } else {
      Session session = sessionFactory.openSession();
      session.setFlushMode(FlushMode.MANUAL);
      SessionHolder sessionHolder = new SessionHolder(session);
      TransactionSynchronizationManager.bindResource(sessionFactory, sessionHolder);
   }
   return false;
}

// 关闭Session方法
public static void closeHibernateSessionFromThread(boolean participate, Object sessionFactory) {
   if (!participate) {
      SessionHolder sessionHolder = (SessionHolder) TransactionSynchronizationManager
            .unbindResource(sessionFactory);
      SessionFactoryUtils.closeSession(sessionHolder.getSession());
   }
}
