I had the same problem, hope my solution work for you too:
我遇到了同样的问题，希望我的解决方案也适用于您：
1: since you're using hibernate-c3p0-4.1.10.Final.jar, your provider_class should be:
1：由于您使用的是 hibernate-c3p0-4.1.10.Final.jar，您的 provider_class 应该是：
<property name="connection.provider_class">org.hibernate.connection.C3P0ConnectionProvider</property>
从错误引起：org.hibernate.HibernateException：无法实例化连接提供程序[org.connection.C3P0ConnectionProvider]
Also, make sure you include both c3p0-0.9.1.jar and hibernate-c3p0-4.2.1.Final.jar (should be in the same folder "\hibernate-release-4.2.1.Final\lib\optional\c3p0\" )
另外，请确保同时包含 c3p0-0.9.1.jar 和 hibernate-c3p0-4.2.1.Final.jar（应在同一文件夹中“\hibernate-release-4.2.1.Final\lib\optional\c3p0 \" )
I ended up downloading the latest Hibernate release (4.2.1) here http://planet.jboss.org/post/hibernate_orm_4_2_1_final_and_4_1_12_final_released
我最终在这里下载了最新的 Hibernate 版本 (4.2.1) http://planet.jboss.org/post/hibernate_orm_4_2_1_final_and_4_1_12_final_released
and updating all the hibernate related jars in my project to get it to work properly, since the download link in eclipse only has the 3.6.0 Final version (JBoss Hibernate - http://download.jboss.org/jbosstools/updates/stable/)
并更新我项目中所有与 hibernate 相关的 jars 以使其正常工作，因为 eclipse 中的下载链接只有 3.6.0 最终版本（JBoss Hibernate - http://download.jboss.org/jbosstools/updates/stable /)

Add the above lirary jar files found in your hibernate distribution lib directory
添加上述在您的 hibernate 发行版 lib 目录中找到的 lirary jar 文件
