使用openSessionInViewFilter出现could not initialize proxy - no Session异常

Question

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？

Answer 1

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。

Answer 2

  应该是2个session已经不是同一个对象了！

Answer 3

用了OpenSessionInViewFilter，还会有2个不同的session？

Answer 4

<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>
<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>
<filter-mapping>
<filter-name>hibernateFilter</filter-name>
<url-pattern>/*</url-pattern>
</filter-mapping> <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顺序应该也没错

Answer 5

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

Answer 6

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？

Answer 7

加了   我把整个web.xml传上来吧

Answer 8

这是全部的web.xml的配置<?xml version="1.0" encoding="UTF-8"?>

Answer 9

applicationContext-*.xml 之间有没有谁import谁这种关系啊。

Answer 10

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。
