后来一点点缩减排除可能的情况, 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.

打出该消息的那个项目上有maven依赖:

<dependency>
    	<groupId>ch.qos.logback</groupId>
    	<artifactId>logback-classic</artifactId>
    	<version>0.9.27</version>
    </dependency>

删除该依赖就没有了这些消息, 这些消息对测试运行是没什么影响的, 如果不是强迫症, 不必做修改.

Stackoverflow上给出的说法如下:

In the log messages and stack traces that you've shown, there is nothing wrong at all. These are all DEBUG level messages. (c3p0 & com.mchange libraries should usually be logged at INFO.)  
c3p0 & mchange-commons-java check for potential config information in lots of different places. In many of those places, they find nothing, and so move on. Logging at DEBUG, you are watching the process of libraries checking for, e.g., /mchange-log.properties, in the CLASSPATH and failing to find it. At DEBUG, the libraries log that they looked, that they did not find, and the Exception that went along with not finding.  
None of this is of concern at all. It is normal.  
The main question is whether the config users put in c3p0-config.xml is taking. You are using a relative directory for the file, rather than an absolute filesystem location. I presume that will work, with relative being interpreted relative to the working directory of the process, but I'm not sure it will work, and even if it does, are you sure that it won't be fragile, depend on how users start up your process? Will users run a script that will ensure the proper working directory?
