同学好，遇到此类问题，可以在我们问答区先搜搜看看有没有类似的问题和答案，这里你只需要搜索

No bean named 'com.mchange.v2.c3p0.ComboPooledDataSource' available

或者搜索

ComboPooledDataSource

一般就是caused by 附近的语句

就会发现有和你类似的，请参照这个问答的帖子解决：）

同理可以把这些错误贴到网上，提前锻炼自己解决问题的能力，对以后工作很有帮助哦

  老师你好，我重新Repository里面jar包删除后，执行了update maven project clean下载jar，还是报 Caused by: org.springframework.beans.factory.BeanDefinitionStoreException: Invalid bean definition with name 'dataSource' defined in class path resource [spring-dao.xml]: Could not resolve parent bean definition 'com.mchange.v2.c3p0.ComboPooledDataSource'; nested exception is org.springframework.beans.factory.NoSuchBeanDefinitionException: No bean named 'com.mchange.v2.c3p0.ComboPooledDataSource' available
  和 No bean named 'com.mchange.v2.c3p0.
  ComboPooledDataSource' available。

  同学好，应该还是maven配置有问题，eclipse已经与maven连接了对不，就是和截图里的一样的连接，连接好之后，可以换个maven镜像试试，网上也是一样的问题，也是由于jar虽然显示有了但是下不全的缘故
