关于SSH整合中对于Hibernate的Session关闭的问题

在web.xml的Struts2的配置上面加上

<filter>
     <filter-name>OpenSessionInViewFilter</filter-name>
         <filter-class>
             org.springframework.orm.hibernate4.support.OpenSessionInViewFilter
         </filter-class>
        <init-param>
             <param-name>singleSession</param-name>
             <param-value>true</param-value>
        </init-param>
   </filter>
   <filter-mapping>
       <filter-name>OpenSessionInViewFilter</filter-name>
       <url-pattern>/*</url-pattern>
    </filter-mapping>
