未找到休眠 4 ConnectionProvider 类

Question

我刚刚将我的应用程序中的 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。

下一个我没有发现的问题是，我现在在 org.hibernate.connection.ConnectionProvider 上遇到了 ClassNotFoundException

需要注意的是，我的连接池使用的是 BoneCP (0.7.1)，它在升级之前就可以工作。

任何帮助将不胜感激。我对休眠很陌生（我正在努力将其作为 POC 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，但如果有最新最好的版本就好了:)

谢谢！

Hibernate.cfg.xml sn-p（已替换敏感信息）：

        <property name="hibernate.connection.driver_class">com.mysql.jdbc.Driver</property>
        <property name="hibernate.connection.url">foo</property>
        <property name="hibernate.connection.username">bob</property>
        <property name="hibernate.default_schema">bar</property>
        <property name="hibernate.dialect">package.path.MySQLCustomDialect</property>

        <!-- Bonecp connection pool -->
        <property name="hibernate.connection.provider_class">com.jolbox.bonecp.provider.BoneCPConnectionProvider</property>
        <property name="bonecp.maxConnectionAgeInMinutes">5</property>
        <property name="bonecp.idleConnectionTestPeriodInMinutes">0</property>
        and so on ...

Hibernate 不断更改包含ConnectionProvider 基类的包。它从第 3 版更改为第 4 版，并在 4.3 版中再次更改。 正如@teresa-carrigan 在对this answer 的评论中提到的那样，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 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）。
