1、我的解决途径：该问题很大可能是部署项目的数据库配置不正确导致（我的是这种情况），还有可能是其他原因——这个可以通过百度搜索——tomcat cp30进行查询
2、如除上面的错误还伴随以下报错2014-10-24 15:35:44,515 [Timer-0] WARN [com.mchange.v2.async.ThreadPoolAsynchronousRunner] - Task com.mchange.v2.resourcepool.BasicResourcePool$AcquireTask@188a387 (in deadlocked PoolThread) failed to complete in maximum time 60000ms.
