我的applicationContext 里面明明配置的是dbcp，tomcat启动的时候 为什么会提示找不到c3po
2015-3-18 14:21:41 org.springframework.web.context.ContextLoader initWebApplicationContext
严重: Context initialization failed
org.springframework.beans.factory.CannotLoadBeanClassException: Cannot find class [com.mchange.v2.c3p0.ComboPooledDataSource] for bean with name 'dataSource' defined in ServletContext resource [/WEB-INF/applicationContext.xml]; nested exception is java.lang.ClassNotFoundException: com.mchange.v2.c3p0.ComboPooledDataSource
而且我的项目中也添加了dbcp的jar包
下面是我的applicationContext.xml的内容

------解决思路----------------------
清理一下服务器缓存，重新部署一下，再启动试试
在你的工程中搜一下com.mchange.v2.c3p0.ComboPooledDataSource 看是否存在这个class的配置
