java.lang.IllegalStateException: No value for key [org.hibernate.impl.SessionFactoryImpl@af9ce7] bou

最近写代码遇到的。

问题代码如下：

 public Object dottCreateByTablename(Object vo,String tablename) throws Exception {
  Session session = SessionUtils.currentSession(getDbFlag());
  try {   
   session.save(tablename, (Object) vo);
   session.flush();
  } catch (HibernateException ex) {
   /**
    * 一般来说，Hibernate处理异常时都用HibernateException包装之后抛出，
    * 这里尝试解开HibernateException的包装，出示真正的错误原因。
    */
   if (ex.getCause() != null) {
    throw new Exception(ex.getCause());
   } else {
    throw ex;
   }
  }finally{
   session.close();
  }
  return vo;
 }

就是这个session关闭了。导致出现的错误。为什么呢？具体我也不知道。具体场景如下：

首先记录入哪张表是不确定的，由传入的表名确定的。因为表结构一致，只是表名不一样，所以VO用了一个，对应的hibernate配置如下：

</hibernate-mapping>

然后当多笔记录入库就会有异常出现：

最后取消了session的关闭，就没有异常了。原因我也不是非常清楚。。。
