在项目中SSH或SSH2中OpenSessionInViewFilter的配置顺序（实质过滤器的配置顺序）

   网上一些网友上在项目中SSH或SSH2中OpenSessionInViewFilter的配置顺序（实质过滤器的配置顺序），配置了但是报session关闭的错误，其实原因在Filter配置顺序的原因：

SSH2正确顺序：

OpenSessionInViewFilter

ActionContextCleanUp

FilterDispatcher

以及其他的Filter

 

配置：

 <filter>
  <filter-name>openSessionInViewFilter</filter-name>
  <filter-class>
   org.springframework.orm.hibernate3.support.OpenSessionInViewFilter
  </filter-class>
  <init-param>
   <param-name>sessionFactoryBeanName</param-name>
   <param-value>hibernate.sessionFactory</param-value>
  </init-param>
 </filter>

 

 

注意：无论怎么配置OpenSessionInViewFilter的配置顺序很重要！！同时配置SessionFactory的名称。

 

 

 

struts/spring/hibernate的时候同样使用OpenSessionInView：

1.首先是web.xml

	<filter>
        <filter-name>OpenSessionInViewFilter</filter-name>
        <filter-class>org.springframework.orm.hibernate.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>

......

 

2. 然后是struts-config.xml：

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

 

 

 

 

S2SH配置：

applicationContext.xml配置如下：

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
	xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:context="http://www.springframework.org/schema/context"
	xmlns:aop="http://www.springframework.org/schema/aop" xmlns:tx="http://www.springframework.org/schema/tx"
	xsi:schemaLocation="http://www.springframework.org/schema/beans 
           http://www.springframework.org/schema/beans/spring-beans-2.5.xsd
           http://www.springframework.org/schema/context
           http://www.springframework.org/schema/context/spring-context-2.5.xsd
           http://www.springframework.org/schema/aop
           http://www.springframework.org/schema/aop/spring-aop-2.5.xsd
           http://www.springframework.org/schema/tx
		   http://www.springframework.org/schema/tx/spring-tx-2.5.xsd">
		   
	<context:component-scan base-package="com.fsj" /><!-- 启用自动扫描 -->
	<!-- 基于hibernate注解的sessionFactory -->
	<bean id="sessionFactory"
		class="org.springframework.orm.hibernate3.annotation.AnnotationSessionFactoryBean">
		<property name="configLocation" value="classpath:hibernate.cfg.xml">
		</property>
	</bean>
	<!-- 基于hibernate的事务管理器 -->
	<bean id="txManager" class="org.springframework.orm.hibernate3.HibernateTransactionManager">
		<property name="sessionFactory" ref="sessionFactory" />
	</bean>
	<!-- 采用注解形式的声明式事务管理 -->
	<tx:annotation-driven transaction-manager="txManager"/>
	
</beans>

 

web.xml如下设置：

<?xml version="1.0" encoding="UTF-8"?>
<web-app version="2.5" 
	xmlns="http://java.sun.com/xml/ns/javaee" 
	xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" 
	xsi:schemaLocation="http://java.sun.com/xml/ns/javaee 
	http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd">
	
	<context-param>
	   <param-name>contextConfigLocation</param-name>
	   <param-value>classpath:applicationContext.xml</param-value>
	</context-param>
	
	<listener>
	      <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
	</listener>
		
						
	<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>
	
	<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>
		
	<filter>
		<filter-name>encoding</filter-name>
		<filter-class>org.springframework.web.filter.CharacterEncodingFilter</filter-class>
		<init-param>
			<param-name>encoding</param-name>
			<param-value>UTF-8</param-value>
		</init-param>
	</filter>
	<filter-mapping>
		<filter-name>encoding</filter-name>
		<url-pattern>/*</url-pattern>
	</filter-mapping>
		
</web-app>

 

struts.xml配置：

<?xml version="1.0" encoding="UTF-8" ?>
<!DOCTYPE struts PUBLIC
    "-//Apache Software Foundation//DTD Struts Configuration 2.0//EN"
    "http://struts.apache.org/dtds/struts-2.0.dtd">

<struts>

	<!-- 指定Web应用的默认编码集,相当于调用HttpServletRequest的setCharacterEncoding方法 -->
	<constant name="struts.i18n.encoding" value="UTF-8" />
	<!-- 设置浏览器是否缓存静态内容,默认值为true(生产环境下使用),开发阶段最好关闭 -->
	<constant name="struts.serve.static.browserCache" value="false" />
	<!-- 当struts的配置文件修改后,系统是否自动重新加载该文件,默认值为false(生产环境下使用),开发阶段最好打开 -->
	<constant name="struts.configuration.xml.reload" value="true" />

	<constant name="struts.devMode" value="true" />
	<!-- 默认的视图主题 -->

	<!-- 把action对象交给spring创建 -->

	<package name="myDefault" extends="struts-default">

			</result>
		</global-results>
		<global-exception-mappings>
			<exception-mapping result="exceptionPage" exception="java.lang.Exception" />
		</global-exception-mappings>		
		<action name="indexPage">
			<result>/login.jsp</result>
		</action>
	</package>

	<package name="user" namespace="/user" extends="myDefault">
		<!-- 这里面的class不是指完整类路径，而是指在spring中定义的bean的名称 -->
		<action name="*UserAction" class="userAction" method="{1}">
			<result name="success">/WEB-INF/user/loginSuccess.jsp</result>
			<result name="input">/login.jsp</result>
		</action>
	</package>

</struts>

 

 

   项目中采用单一的SessionFactory，如果有多个SessionFactory该怎么办呢？希望牛人指点！！
