OpenSessionInView配置方法

web.xml

< 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 >             < listener >        < listener-class > org.springframework.web.context.ContextLoaderListener </ listener-class >    </ listener >

struts-config.xml

< plug-in   className ="org.springframework.web.struts.ContextLoaderPlugIn" >    < set-property  property ="contextConfigLocation"   value ="/WEB-INF/applicationContext.xml" />    </ plug-in >

此处的org.springframework.web.struts.ContextLoaderPlugIn类里的方法initWebApplicationContext()，在getServletContext().setAttribute(attrName, wac);下增加一条属性设置。  getServletContext().setAttribute(WebApplicationContext.ROOT_WEB_APPLICATION_CONTEXT_ATTRIBUTE, wac);

具体原因参考http://www.javaeye.com/topic/15057，里面有很详细的说明
