路过看看！

只是个自己按着书写的一段代码，没有用annotation！！！

<property name="connection.url">jdbc:mysql://localhost/hibernate</property>是不是没有写端口号阿？

应该是缺少ejb3-persistence.jar这个包吧，但似乎LZ没有用到annotation？

貌似是这个问题。。。

[yefei679]

LZ用的hibernate是什么版本的？其实那个类在hibernate-jpa-2.0-api-1.0.0.Final.jar通过添加这个jar包也是可以的，因为hibernate需要jpa的支持的。

看版本了，那个都行。使用hibernate-jpa-2.0-api-1.0.0.Final.jar这个也行。这个不管用不用注解都是必须的！

javax/persistence/EntityListeners 少包了， 没有这个包， 所以这个方法报错了。
