我刚刚将应用程序中的Hibernate更新为4.3.4(从3.X),这引起了一些问题。第一个是我解决的创建sessionFactory的新方法。
我没有发现的下一个问题是,我现在在org.hibernate.connection.ConnectionProvider上收到ClassNotFoundException
应该注意的是,我在连接池中使用的是BoneCP(0.7.1),该连接池在升级之前就可以使用了。
任何帮助,将不胜感激。我刚进入hibernate状态(我正在努力将其实现为POC),因此我可能在这里的描述中遗漏了一些重要的细节。我不需要它是最新版本,因此我可以还原,但是拥有最新,最出色的版本将非常不错:)
谢谢!

Hibernate不断更改包含ConnectionProvider基类的包。它从版本3更改为版本4,并在版本4.3中再次更改。正如@ teresa- carrigan在对此答案的评论中提到的那样,您必须编译最新的BoneCPConnectionProvider.java(当前支持Hibernate 4.3.1)并使用它。 或者使用Hibernate 4.2.12.Final版本,看看它是否适用于BoneCP 0.8(如上述答案中所述)。
