SSH系统异常hibernate.AssertionFailure: collection[] was not processed by flush()
话说问题之前，先把异常堆栈贴出来：19:28:17,671 ERROR AssertionFailure:22 - an assertion failure occured (this may indicate a bug in Hibernate, but is more likely due to unsafe use of the session)

这里，介绍一下问题出现的背景：
为方便后台管理，我使用了机构（IOrganization）与用户（IUser）的一对多双向关联映射，机构（IOrganization）的自关联映射。之前为了做系统审计日志，考虑到日志粒度问题，我采用了基于Hibernate3的事件框架做系统审计日志，日志配置如下：
<property name="eventListeners">
<map>
<entry key="post-update">
<ref bean="auditLog" />
</entry>
<entry key="post-delete">
<ref bean="auditLog" />
</entry>
<entry key="post-insert">
<ref bean="auditLog" />
</entry>
</map>
</property>
当我向机构中增加用户时，问题就出现了，而且问题很蹊跷：当我将审计日志配置注销掉，操作能正常完成；一启用审计日志配置，就报出上述错误。
为这个问题纠结了好几天，在程序中断点跟踪，也没找到出错位置，实在是没辙了。真诚求解释，希望技术大牛们不吝赐教！！！ --------------------编程问答-------------------- 这么久了 居然没有兄弟姐妹和我一起讨论这个话题...... --------------------编程问答-------------------- 这段时间 我在解决这个问题时候已经有所收获。等闲下来 和大家分享一下我的新的体会！！ --------------------编程问答-------------------- LZ 现在拿出来说说啊？ --------------------编程问答-------------------- 暂时查到资料显示可能是hibernate版本的Bug问题 一直在找机会总结一下这类问题，可还一直没来得及 汗颜呀... --------------------编程问答-------------------- 异常提示也是说是hibernate里出现的问题，找了好多资料但是一直都解决不了、、、 --------------------编程问答-------------------- 我在springsource community论坛里看到这个相关问题讨论和解决途径，不过都是英文的，给大家摘录一段：
TO Rama: a masterly idea :-)
I've resolved this problem!
but I did not follow your idea, but thanks for your reply
I switched my hibernate3.0 to hibernate 3.2.6 just as bdangubic said and it worked well
这哥们回复的大概意思是说，使用hibernate3.2.6替换了项目中的hibernate3.0，然后这个问题就解决了。可是我把项目中hibernate版本换掉之后，还是会出现这种问题，我现在项目框架采用的是Struts2.1+Spring3.0+hibernate3.1。因为论坛中没有提到项目除了hibernate做持久层，还是用其他什么架构，所以我现在也不敢随意揣摩。
如果大家有什么好的解决途径，希望慷慨分享一下哦！！ --------------------编程问答-------------------- 你说的那个帖子我也看过了，也试了，我之前的hibernate是3.2.7的，替换之后也不行。我那问题虽然已经解决了，但是是将里面原来的方法分离出来了。我那update方法里面调用了一个方法，那方法也执行了update的操作，但是没有commit。也就是说我那问题相当于是：update update -- commit。调用的那方法执行update操作之后没有commit，所以hibernate提示说启用了一个不安全的会话。 --------------------编程问答-------------------- 使用commit的前提是事务是自己管理的 可是我的系统中事务都交给了Spring来管理的 所以不会涉及到事务问题导致的不安全会话 --------------------编程问答-------------------- 问题原因终于找到了，不过不知道你们的问题是不是这个原因。
原因就是在Hibernate3的事件处理过程中对原始数据进行了访问或处理，导致update与save产生冲突，如果原始数据不是对象而是Integer、String等常规数据类型是没有关系，一旦你调用了many-to-one或者one-to-many之类的就会抛这个异常出来。
所以我最后做日志的时候把many-to-one或者one-to-many的属性去掉不记录就没问题了！ --------------------编程问答-------------------- 汗颜呀，同志们，现在才回来探讨这个问题。我最后采取曲线救国了。由于系统后台要求关联业务操作的细粒度审计日志，而基于Hibernate事件驱动的切面操作无法达到我们审计日志的要求，最后采取了硬编码这种最蠢最笨的方式做审计日志。我现在倒是想重开一帖，和大家讨论一下做后台审计日志的通用做法，既要考虑到系统业务问题，让普通用户（非IT从业人员）也能看懂系统审计日志；也要考虑到审计日志的粒度问题，粒度可以越小越好，可以有记录操作时间，操作数据以及数据的前后变化；操作人信息。最好是审计日志的使用和记录的信息达到可配置状态。就在这和大家讨论这个问题了，愿意讨论者人人有分，虽然分不怎么多，只想和大家共同进步！！ --------------------编程问答-------------------- 汗颜呀，同志们，现在才回来探讨这个问题。我最后采取曲线救国了。由于系统后台要求关联业务操作的细粒度审计日志，而基于Hibernate事件驱动的切面操作无法达到我们审计日志的要求，最后采取了硬编码这种最蠢最笨的方式做审计日志。我现在倒是想重开一帖，和大家讨论一下做后台审计日志的通用做法，既要考虑到系统业务问题，让普通用户（非IT从业人员）也能看懂系统审计日志；也要考虑到审计日志的粒度问题，粒度可以越小越好，可以有记录操作时间，操作数据以及数据的前后变化；操作人信息。最好是审计日志的使用和记录的信息达到可配置状态。就在这和大家讨论这个问题了，愿意讨论者人人有分，虽然分不怎么多，只想和大家共同进步！！ --------------------编程问答-------------------- 美女，现在还可以讨论下这个问题吗。到底是怎么解决的呢。 --------------------编程问答-------------------- 我也这样，解决不了
