。。。。。。。。

[解决办法]
应该是没引入这个包
com.springsource.com.mchange.v2.c3p0-0.9.1.2.jar
[解决办法]
有没有导入连接池的JAR包啊。好像是缺少了C3P0的JAR包。
[解决办法]
楼主你这配置文件是复制的吧，不然不会这么多错误的，我粗略看下
首先:<ref bean="dataSource" />这句话错了吧
还有你用的是不是tomcat
[解决办法]
java.lang.ClassNotFoundException:com.mchange.v2.c3p0.ComboPooledDataSource

缺少了C3P0的JAR包
[解决办法]
重新配置


[解决办法]
java.lang.ClassNotFoundException: com.mchange.v2.c3p0.ComboPooledDataSource
