struts2中OpenSessionInViewFilter无效解决方法

  struts2中OpenSessionInViewFilter无效,能够运行起来了,但是在jsp中迟缓加载数据时,发现session提前关闭了。 Hibernate抛出了异常no session。经过数次尝试,发现在web.xml中,必须要将spring的OpenSessionInViewFilter配置到Struts2的前方才会生效,原因尚不明确,也不去研究了,可能是个bug,其配置如下:

<?xml version="1.0" encoding="UTF-8"?>
<web-app xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
	xmlns="http://java.sun.com/xml/ns/javaee" xmlns:web="http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd"
	xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd"
	id="WebApp_ID" version="2.5">
	<welcome-file-list>
		<welcome-file>index.jsp</welcome-file>
	</welcome-file-list>
	<!--
		指定spring的配置文件,默认从web根目录寻找配置文件,我们可以通过spring提供的classpath:前缀指定从类路径下寻找
	-->
	<context-param>
		<param-name>contextConfigLocation</param-name>
		<param-value>classpath:applicationContext-common.xml</param-value>
	</context-param>
	<!-- 对Spring容器进行实例化 -->
	<listener>
		<listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
	</listener>
	<!-- 使用spring解决hibernate因session关闭导致的延迟加载例外问题(必须配置到Struts2前面) -->
	<filter>
		<filter-name>OpenSessionInViewFilter</filter-name>
		<filter-class>org.springframework.orm.hibernate3.support.OpenSessionInViewFilter</filter-class>
		<init-param>
	   	<!-- 指定org.springframework.orm.hibernate3.LocalSessionFactoryBean在spring配置文件中的名称,默认值为sessionFactory.如果LocalSessionFactoryBean在spring中的名称不是sessionFactory,该参数一定要指定,否则会出现找不到sessionFactory的例外 -->
			<param-name>sessionFactoryBeanName</param-name>
			<param-value>sessionFactory</param-value>
		</init-param>
	</filter>
	<filter-mapping>
	        <filter-name>OpenSessionInViewFilter</filter-name>
	        <url-pattern>/*</url-pattern>
	</filter-mapping>
	<!-- 配置struts2 -->
	<filter>
		<filter-name>struts2</filter-name>
		<filter-class>org.apache.struts2.dispatcher.ng.filter.StrutsPrepareAndExecuteFilter</filter-class>
	</filter>
	<filter-mapping>
		<filter-name>struts2</filter-name>
		<url-pattern>/*</url-pattern>
	</filter-mapping>
</web-app>
