延迟加载配置加到web./demo/view.do?id=xx–>Filter控制器–>ViewAction–>Note

加到web.xml

/demo/view.do?id=xx–>Filter控制器–>ViewAction–>NoteDao.findById–>NOTE–>Result–>/WEB-INF/view.jsp

为了支持Hibernate延迟加载操作load，配置OpenSessionInViewFilter


<!-- opensessioninviewfilter,放在struts2 filter之前 -->
<filter>
    <filter-name>opensession</filter-name>
    <filter-class>
    org.springframework.orm.hibernate4.support.OpenSessionInViewFilter
    </filter-class>
</filter>
<filter-mapping>
    <filter-name>opensession</filter-name>
    <url-pattern>/*</url-pattern>
</filter-mapping>
