以前使用 spring 的 hibernateTemplate 时，发现都无法用 lazyloading 特性因为一旦使用，会报 session close 错误，几经查找资料，终于找到解决方法，就是在 web.xml 中加入下列 filter ：

 

<filter>

       <filter-name>hibernateFilter</filter-name>

       <filter-class>

           org.springframework.orm.hibernate3.support.OpenSessionInViewFilter

       </filter-class>

    </filter>

    <filter-mapping>

       <filter-name>hibernateFilter</filter-name>

       <url-pattern>/*</url-pattern>

    </filter-mapping>
