Java 找不到休眠 4 ConnectionProvider 类

Hibernate 4 ConnectionProvider Class not found

提问by thepoynt

I just updated Hibernate in my application to 4.3.4 (from 3.X), which caused some problems. The first was the new method of creating a sessionFactory, which I resolved.

我刚刚将应用程序中的 Hibernate 更新为 4.3.4（从 3.X 开始），这导致了一些问题。第一个是创建 sessionFactory 的新方法，我解决了。

The next problem, which I'm finding nothing about, is that I am now getting a ClassNotFoundException on org.hibernate.connection.ConnectionProvider

下一个我没有发现的问题是我现在在 org.hibernate.connection.ConnectionProvider 上收到 ClassNotFoundException

It should be noted that I'm using BoneCP (0.7.1) for my connection pool, which was working before the upgrade.

应该注意的是，我使用 BoneCP (0.7.1) 作为我的连接池，它在升级前工作。

Any help would be appreciated. I'm pretty new to hibernate (I'm working on implementing it as a POC), and I may have left out some important details from my description here as such. I don't need it to be the newest version, so I can revert back, but it would be nice to have the latest and greatest :)

任何帮助，将不胜感激。我对 hibernate 还很陌生（我正在努力将它作为 POC 来实现），因此我可能在此处的描述中遗漏了一些重要的细节。我不需要它是最新版本，所以我可以恢复，但是拥有最新最好的会很好:)

Thanks!

谢谢！

Hibernate keeps changing the package containing the ConnectionProviderbase class. It changed from version 3 to 4 and has changed again with verson 4.3. As @teresa-carrigan mentions in a comment to this answer, you'll have to compile the latest BoneCPConnectionProvider.java(currently supporting Hibernate 4.3.1) and use that.
Or use Hibernate version 4.2.12.Final and see if that works with BoneCP 0.8 (as explained in the aforementioned answer).

Hibernate 不断更改包含ConnectionProvider基类的包。它从版本 3 更改为 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，您必须编译最新的BoneCPConnectionProvider.java（目前支持 Hibernate 4.3.1）并使用它。
或者使用 Hibernate 版本 4.2.12.Final 并查看它是否适用于 BoneCP 0.8（如上述答案中所述）。
