<我有同样的问题，希望我的解决方案也适用于你：
1：既然你'重新使用hibernate-c3p0-4.1.10.Final.jar，你的provider_class应该是：
< property name =连接.provider_class> org.hibernate.connection.C3P0ConnectionProvider< /性>
$ b导致的错误：org.hibernate.HibernateException：无法实例化连接提供者[org.connection.C3P0ConnectionProvider] $ b
另外，请确保包含
c3p0-0.9.1.jar和hibernate-c3p0-4.2.1.Final.jar（应位于同一个文件夹\hibernate -release-4.2.1.Final \lib\optional\c3p0\）
我在这里下载了最新的Hibernate发行版（4.2.1） http://planet.jboss.org/post/hibernate_orm_4_2_1_final_and_4_1_12_final_released
并更新我的项目中所有与hibernate相关的jar以使其正常工作，因为eclipse中的下载链接仅具有3.6.0最终版本（JBoss Hibernate - http://download.jboss.org/jbosstools/updates/stable/ ）

解决方案
I had the same problem, hope my solution work for you too:
1: since you're using hibernate-c3p0-4.1.10.Final.jar, your provider_class should be:
<property name="connection.provider_class">org.hibernate.connection.C3P0ConnectionProvider</property>
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\" )
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
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/)
这篇关于我无法运行C3P0ConnectionProvider的文章就介绍到这了，希望我们推荐的答案对大家有所帮助，也希望大家多多支持IT屋！
