Hibernate的二级缓存+的Ehcache问题

我能够通过使用HibernateTemplate.load(Class entityClass, Serializable id)摆脱高速缓存，但只有一个对象的数据，Hibernate的二级缓存+的Ehcache问题

任何人都可以帮助我解决这个问题？ – Sandy 2012-03-08 13:31:52

摆脱你的警告，并尝试.....这里没有太多的东西要继续下去。 “[WARN] [org.hibernate.mapping.RootClass] [composite-id类不覆盖equals（）：com.uprr.app.rim.components.exinterface.domain.Track] [2012-03-06 04:34 ：20,270] [WARN] [org.hibernate.mapping.RootClass] [复合id类不覆盖hashCode（）：“ – 2012-03-08 13:47:33

删除警告但仍然相同的问题.. :( – Sandy 2012-03-08 15:32:57

一世当激活二级缓存&试图缓存我的标准时，它实际上面临同样的问题。

如果我不设置缓存为true，

更新：我终于找到了解决办法，问题就来了从我的休眠版本。我在休眠3.2。升级到3.6.9解决了我的问题:)

希望它可以帮助！
