解决方法：
【原因】：发现打出这些错误的那个项目配置了slf4j日志, 猜测是c3p0使用了slf4j进行日志记录, 当检测到有该jar包时, 使用DEBUG级别打印出调试消息.
这个并不影响项目使用，但是强迫症必用
pom.xml文件中这个删掉：
<dependency> <groupId>ch.qos.logback</groupId> <artifactId>logback-classic</artifactId> <version>1.1.7</version> <scope>runtime</scope> </dependency>
以上是关于c3p0报错：java.io.FileNotFoundException: Resource not found at path '/mchange-log.properties'(代的主要内容，如果未能解决你的问题，请参考以下文章
