显然，DefaultPersistEventListener.onPersist()出了问题。我坚持使用一个网站实体，如果与该实体关联的LazyInitializer是未初始化的，则抛出此异常。

http://www.jarvana.com/jarvana/view/org/hibernate/hibernate/3.1/hibernate-3.1-sources.jar!/org/hibernate/event/def/DefaultPersistEventListener.java?format=ok

我不知道为什么会这样。有什么想法吗？

编辑：

在我的web.xml中，我有一个hibernateFilter：

<filter>
    <filter-name>hibernateFilter</filter-name>
    <filter-class>org.springframework.orm.hibernate3.support.OpenSessionInViewFilter</filter-class>
    <init-param>
        <param-name>sessionFactoryBeanName</param-name>
        <param-value>sessionFactoryAdmin</param-value>
    </init-param>
    <init-param>
        <param-name>flushMode</param-name>
        <param-value>AUTO</param-value>
    </init-param>
</filter>

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