找不到Hibernate 4 ConnectionProvider类

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.cfg.xml代码段（已替换敏感信息）：

<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 ...

回答：

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）。
