Question

业务层：

public class ServiceImpl implements Service{

  @Transactional(readOnly = false)
   public void createOrUpdateAppPing(String s) {

      servicePingDao.createOrUpdateAppPing(s);
   }
}

Dao图层

public   void createOrUpdateAppPing(String sc) {
      EntityManager  entityManager = entityManagerFactory.createEntityManager();    
          pingScService(sc,entityManager);
          if(ifHasPingScConfig(sc,entityManager)) {
             updateScConfig(sc,entityManager);
          } else {
             createScConfig(sc,entityManager);      }
         entityManager.close();    
   }

这里： ** pingScService有选择查询 ** updateScConfig - 更新查询 ** createScConfig-insert

现在我想在服务层添加事务支持......我怎么能这样做。

我尝试添加@Transaction注释，但我正在
