使用openSessionInViewFilter出现could not initialize proxy - no Session异常

[KG071]

web.xml中的一个片段

	<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>

配置了这个为何还是会有lazy方面的异常？

今天上午回复你的帖子有点草率，先跟你说声对不起啦。

“could not initialize proxy” 如果抛出这样的异常的话， 还是说明你声明了事务的。

我现在也一下子也吃不准你这个到底什么原因了。建议你测试一下，看看你持久层拿到session 和 OpenSessionInView的过滤器的新建的session到底是不是同一个对象。

我冷静地想一想症结或许在这里，大概是哪里配置错了，造成Spring的IoC容器启动了两个。

应该是2个session已经不是同一个对象了！

用了OpenSessionInViewFilter，还会有2个不同的session？

[KG071]

<filter>
		<filter-name>Spring character encoding filter</filter-name>
		<filter-class>org.springframework.web.filter.CharacterEncodingFilter</filter-class>
		<init-param>
			<param-name>encoding</param-name>
			<param-value>GBK</param-value>
		</init-param>
	</filter>
	<filter-mapping>
		<filter-name>Spring character encoding filter</filter-name>
		<url-pattern>/*</url-pattern>
	</filter-mapping>

	<filter>

			<param-value>true</param-value> 
		</init-param> 
	</filter>
	<filter-mapping>
		<filter-name>hibernateFilter</filter-name>
		<url-pattern>/*</url-pattern>
	</filter-mapping>

	<filter>
		<filter-name>struts2</filter-name>

	</filter>
	<filter-mapping>
		<filter-name>struts2</filter-name>
		<url-pattern>/*</url-pattern>
	</filter-mapping>

filter顺序应该也没错

[KG071]

<ref local="sessionFactory"/>和<ref="sessionFactory"/>有区别吗？

[yingzhuo2011]

你没有配置事务！！！

[yingzhuo2011]

爱莫能助了。 阿弥陀佛。

[cheneyfeng3]

openSessionInView 这个是有生命周期的。是再一次请求中有效的。如果的不是在一次请求中调用的。

web.xml

<listener>
	<listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>  
</listener>
  
<context-param>  
	<param-name>contextConfigLocation</param-name>  
	<param-value>
            /WEB-INF/applicationContext1.xml
            /WEB-INF/applicationContext2.xml
        </param-value>
</context-param>

这个没加吗？

加了 我把整个web.xml传上来吧
