Spring解决hibernate因session关闭导致的延迟加载例外问题

只需在web.xml中添加在视图中打开session过滤器，使得session跨越servlet或jsp
 <filter>
         <filter-name>OpenSessionInViewFilter</filter-name>
         <filter-class>org.springframework.orm.hibernate3.support.OpenSessionInViewFilter</filter-class>
 </filter>
 <filter-mapping>
         <filter-name>OpenSessionInViewFilter</filter-name>
         <url-pattern>/*</url-pattern>
 </filter-mapping>
