mysql - 无法将 C3P0PooledDataSource 类型的属性值转换为属性 dataSource 所需的类型 javax.sql.DataSource

过去几周我从这个网站收集了许多有用的答案。我加入是为了对一些我认为最有帮助的答案+1，但目前还无法做到这一点。不过谢谢!

我的问题是 JBoss 7 AS 部署错误，我似乎无法追踪任何相关信息。它开始了一个关于使用 C3P0 的 Spring、Hibernation 和 MySql 的教程。

这是来自服务器的日志，显示我正在尝试更正的错误。

我在独立配置中使用 Eclipse 4.3.0、Maven 3.1、Spring 3.2.4.RELEASE、Hibernate 4.1.0.Final、JBoss EAP 6.1。
