com.mchange.v2.c3p0.impl.AbstractPoolBackedDataSource getPoolManager

如果出现以下错误,是c3p0jar包版本低下的问题,需要配置更高版本的.解决方法截图如下:

1.在maven仓库里面更换jar包
https://mvnrepository.com/search?q=c3p0
选择红框里的最新版本重新覆盖配置文件的面原来的低版本即可

有些同学进不去的代码块如下:

<!-- https://mvnrepository.com/artifact/com.mchange/c3p0 -->
<dependency><groupId>com.mchange</groupId><artifactId>c3p0</artifactId><version>0.9.5.2</version>
</dependency>
