Java Hibernate无状态会话，“语句已关闭”异常

您好，我正在使用无状态会话接口进行批量插入，我遇到了一个异常：语句已关闭

下面是我在代码中使用的详细信息，我通过谷歌获得了这个例外，但没有找到解决方案

示例代码：

hibernate.cfg.xml

---

您能告诉我如何解决此异常吗？

在代码正确缩进后，这看起来不正确，您能更正代码吗？

    @Name("sample")
    @Scope(ScopeType.STATELESS)
    @AutoCreate
    public Sample{  

        @In
        private SessionFactory hibernateSessionFactory;

        @Begin(join=tru)
        public void migrate(){
            StatelessSession session = hibernateSessionFactory.openStatelessSession();
            Transaction tx = session.beginTransaction();
            for(DoTempCustomers tempCust:doTempCustomers){
                  TempCustomers temp=new TempCustomers();
                  BeanUtils.copyProperties(temp, tempCust);
                  session.insert(temp);
            }       
        }

        tx.commit();
        session.close();
     }
  }
