C3P0的坑

1.日志    C3P0自带了mchange-commons包,里头自己实现了一个日志框架.默认会用这个.导致程序使用Logback而C3P0却用自己的mchange-commons.要解决这个问题有两种方案

c3p0连接池的使用

connection，而是通过c3p0数据源的类来获取连接，可分为两种情况，用或者不用配置文件：1.不用配置文件，采用硬编码的形式设置连接池参数：导入c3p0的jar包:c3p0-0.9.5.1.jar以及mchange-commons

今天在启动一个web工程时，发现tomcat卡住了，但又没报错！（此时tomcat并没有启动完成）。好几次都是这样，百思不得其解，原先以为是tomcat设置的timeout时间太短，故而通过双击tomcat，在Timeouts里面将延时时间加大，但同样，启动过程中依然发现在超过新规定的timeout之后停止。如图： 后来，决定看一看控制台的日志：发现日志真的非常重要！！！最后一次卡在的地方，控制台
