使用struts2 +hibernate+spring 做一個項目時，配置tomcat數據源刷新40多次就會報
Cannot get a connection, pool error Timeout waiting for idle object錯誤。
感覺就是spring管理的session沒有到達釋放
網上查資料說沒有配置OpenSessionInViewFilter 而導致的，而我已經配置了OpenSessionInViewFilter ，實在是沒找到頭緒
web.xml配置內容爲
<listener> <listener-class> com.going.framework.spring.web.context.ContextLoaderListener </listener-class> </listener> <filter> <filter-name>Struts2</filter-name> <filter-class> org.apache.struts2.dispatcher.FilterDispatcher </filter-class> </filter> <filter-mapping> <filter-name>Struts2</filter-name> <url-pattern>/*</url-pattern> </filter-mapping> <filter> <filter-name>hibernateFilter</filter-name> <filter-class> org.springframework.orm.hibernate3.support.OpenSessionInViewFilter </filter-class> </filter> <filter-mapping> <filter-name>hibernateFilter</filter-name> <url-pattern>/*</url-pattern> </filter-mapping> 後來查閱大量資料後才發現 問題所在，應該先配置OpenSessionInViewFilter後再配置struts2的跳轉，這樣才能避免Cannot get a connection, pool error Timeout waiting for idle object這問題
