registered the JDBC driver [com.alibaba.druid.proxy.DruidDriver] but failed to unregister

在做这个医药采购项目刚开始搭建整个框架的时候，出现了这个问题。我记得在做上一个商贸项目的时候也出现了这个问题，不过上一次使用的是c3p0连接池，也是报了这么一个错。说是找不到JDBC driver，我修改了applicationContext.xml中关于连接池的文件，清理web层之后，重新运行项目始终不行。
自己开始回忆上一次是怎么解决的了，后来我对整个聚合工程进行Maven clean，而不是单单的只对web层一个模块进行Maven clean后。再运行之后，我发现重要显示的不是这个错误了，虽然还有别的错误。说明对于聚合工程而言，最好对整个工程进行clean，否则修改的一些配置文件可能不生效。
