hibernate中OpenSessionInViewFilter的笔记 (转)
<!-- 过滤spring中对于hibernate的session关闭管理 --> <filter> <filter-name>hibernateFilter</filter-name> <filter-class> org.springframework.orm.hibernate3.support.OpenSessionInViewFilter </filter-class> <init-param> <param-name>singleSession</param-name> <param-value>true</param-value> </init-param> </filter> <!--过滤.jsp和.do结尾的url--> <filter-mapping> <filter-name>hibernateFilter</filter-name> <url-pattern>*.do</url-pattern> </filter-mapping> <filter-mapping> <filter-name>hibernateFilter</filter-name> <url-pattern>*.jsp</url-pattern> </filter-mapping>
?如果是singleSession=false的话，就不会在每次的整个request的过程中使用同一个hibernate session,而是每个数据访问都会产生各自的seesion,等于没有Open Session in View。
OpenSessionInViewFilter调用流程: request(请求)->open session并开始transaction->controller->View(Jsp)->结束transaction并close session。”
