Question

我刚刚在我的应用程序中将Hibernate更新为4.3.4（来自3.X），这导致了一些问题。第一个是创建sessionFactory的新方法，我解决了这个问题。

我没有发现任何问题的下一个问题是我现在在org.hibernate.connection.ConnectionProvider上获得了ClassNotFoundException

应该注意的是，我使用BoneCP（0.7.1）作为我的连接池，它在升级之前正在运行。

任何帮助将不胜感激。我很熟悉hibernate（我正在努力将其作为POC实现），而我可能已经从我的描述中遗漏了一些重要细节。我不需要它成为最新版本，所以我可以回复，但拥有最新最好的版本会很好:)（/ p>

谢谢！

Hibernate.cfg.xml片段（已更换敏感信息）：

<hibernate-configuration>
    <session-factory>
        <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。它从版本3更改为4，并再次更改为第4.3节。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版本4.2.12.Final，看看它是否适用于BoneCP 0.8（如上述答案中所述）。

找不到Hibernate 4 ConnectionProvider类
