Java 部署期间JBoss hibernate异常

我有几个实体的应用程序。在JBoss AS7上部署时，出现以下异常：

我在使用idea 11.1.3；ubuntu 12.04；maven 3.0.3，如果需要，我可以显示项目的pom文件

它是什么意思

重复属性映射

？

它看起来像属性

私有长版本。从其中一个中删除它，它应该可以工作。

基类RQObject是否也有版本属性？是。KLadrSettings覆盖它基类RQObject是否也有版本属性？是。Kladr你的回答对meSo很有帮助我做不到这样的事：用SomeProperty+getter/setter创建超级类，然后扩展这个超类，在子类中再次重写这个someProperty，例如，在从同一个超类派生的不同子类中有不同的Bean验证约束？你的回答对meSo非常有帮助，我不能这样做：用someProperty+getter/setter创建超类，然后扩展这个超类，在子类中再次重写这个someProperty，例如，在从同一个超类派生的不同子类中有不同的Bean验证约束？
