你好 你说的方法保存成功了，但是仍然抛出一个异常貌似是个hibernate的 bug
76354 ERROR 2010-05-09 14:42:03178 org.hibernate.AssertionFailure an assertion failure occured (this may indicate a bug in Hibernate, but is more likely due to unsafe use of the session)
org.hibernate.AssertionFailure: null identifier

你用的Hibernate的哪个版本？
帮你解决问题怎么不给分？都1周了。
