关于 zk spring hibernate 的session问题

zk配置如下：<!-- Optional -->
<listener>
<description>[Optional] Mointor the statistic</description>
<listener-class>org.zkoss.zk.ui.util.Statistic</listener-class>
</listener>
<listener>
      <description>Hibernate SessionFactory lifecycle</description>
      <listener-class>org.zkoss.zkplus.hibernate.HibernateSessionFactoryListener</listener-class>
   </listener>
   <!-- Hibernate OpenSessionInView Pattern -->
   <listener>
      <description>Hibernate Open Session In View life-cycle</description>
      <listener-class>org.zkoss.zkplus.hibernate.OpenSessionInViewListener</listener-class>
   </listener>   <!-- Hibernate thread session context handler -->
   <listener>
      <description>Hibernate thread session context handler</description>
      <listener-class>org.zkoss.zkplus.hibernate.HibernateSessionContextListener</listener-class>
   </listener>
------------------------------------------------------------------------------------------------------------部分页面代码：
public void showList() { Listbox listbox = (Listbox) getFellow("datas");
listbox.getItems().clear();
UnitInfoDAO unitInfoDao = (UnitInfoDAO) SpringUtil
.getBean("unitInfoDao");

UnitInfoDAO unitInfoDao = (UnitInfoDAO)ctx.getBean("unitInfoDao");
System.out.println(unitInfoDao.findUnitInfobyId("4aff264b20d1dd9e0120d1dda5630001"));
。
---------------------------------------------------------------------------------------------------------
页面调用getHibernateTemp().load(id);是抛如下异常，总感觉Hibernate Open Session In View 没起作用
