Not allowed to create transaction on shared EntityManager

您不能像这样启动事务。

您应该像这样使用声明性事务：

@Service
@Persistent
public class ProjectService {@PersistenceContextprivate EntityManager em;private Session session;@Transactionalpublic void insertEmployee throws Exception{em.createNativeQuery("insert into Employee (name,surname,) values('Phil','Bob'").executeUpdate();      }
}
