集成C3P0连接池后控制台狂抛com.mchange.v2.c3p0.SQLWarnings错误解决方案

      在sqlserver2008集成C3P0连接池时，很多朋友添加网上下载的sqlserver驱动jar包后，会报如下的SQLWarning，原因是因为jar包的原因，网上很多下载下来的都是四个jar文件的，但是如果你都添加上去，C3P0默认会去找低版本支持的jar包，但是sqlserver2008官方驱动jar包其实就一个，微软在sqlserver2008之后就对其进行了优化，并且链接url、驱动名称也做了相应的改动，如果你的运行环境是jdk版本是5或者以上，你只需要添加一个jar包即可，控制台便不会出现如下的SQLWarning信息，jar名称为sqljdbc4.jar，附上驱动名称：com.microsoft.sqlserver.jdbc.SQLServerDriver， JDBC_URL：jdbc:sqlserver://192.168.50.88:1433;DatabaseName=xxxx，方便注册驱动不成的朋友对号入座
