方法/步骤
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——tomcatcp30进行查询
2、如除上面的错误还伴随以下报错2014-10-2415:35:44,515[Timer-0]WARN[com.mchange.v2.async.ThreadPoolAsynchronousRunner]-Taskcom.mchange.v2.resourcepool.BasicResourcePool$AcquireTask@188a387(indeadlockedPoolThread)failedtocompleteinmaximumtime60000ms.Tryinginterrupt().2014-10-2415:35:44,515[Timer-0]WARN[com.mchange.v2.async.ThreadPoolAsynchronousRunner]-Taskcom.mchange.v2.resourcepool.BasicResourcePool$AcquireTask@1a81bd5(indeadlockedPoolThread)failedtocompleteinmaximumtime60000ms.Tryinginterrupt().2014-10-2415:35:44,515[Timer-0]WARN[com.mchange.v2.async.ThreadPoolAsynchronousRunner]-Taskcom.mchange.v2.resourcepool.BasicResourcePool$AcquireTask@1bb60ad(indeadlockedPoolThread)failedtocompleteinmaximumtime60000ms.Tryinginterrupt().2014-10-2415:35:44,515[Timer-0]WARN[com.mchange.v2.async.ThreadPoolAsynchronousRunner]-Taskcom.mchange.v2.resourcepool.BasicResourcePool$AcquireTask@c80e21(indeadlockedPoolThread)failedtocompleteinmaximumtime60000ms.Tryinginterrupt().2014-10-2415:35:44,515[Timer-0]WARN[com.mchange.v2.async.ThreadPoolAsynchronousRunner]-Taskcom.mchange.v2.resourcepool.BasicResourcePool$AcquireTask@17bcd4(indeadlockedPoolThread)failedtocompleteinmaximumtime60000ms.Tryinginterrupt().2014-10-2415:35:44,515[Timer-0]WARN[com.mchange.v2.async.ThreadPoolAsynchronousRunner]-Taskcom.mchange.v2.resourcepool.BasicResourcePool$AcquireTask@6e3fe4(indeadlockedPoolThread)failedtocompleteinmaximumtime60000ms.Tryinginterrupt().2014-10-2415:35:44,515[Timer-0]WARN[com.mchange.v2.async.ThreadPoolAsynchronousRunner]-Taskcom.mchange.v2.resourcepool.BasicResourcePool$AcquireTask@24c22b(indeadlockedPoolThread)failedtocompleteinmaximumtime60000ms.Tryinginterrupt().2014-10-2415:35:44,515[Timer-0]WARN[com.mchange.v2.async.ThreadPoolAsynchronousRunner]-Taskcom.mchange.v2.resourcepool.BasicResourcePool$AcquireTask@147a16f(indeadlockedPoolThread)failedtocompleteinmaximumtime60000ms.Tryinginterrupt().2014-10-2415:35:44,515[Timer-0]WARN[com.mchange.v2.async.ThreadPoolAsynchronousRunner]-Taskcom.mchange.v2.resourcepool.BasicResourcePool$AcquireTask@1b78953(indeadlockedPoolThread)failedtocompleteinmaximumtime60000ms.Tryinginterrupt().2014-10-2415:35:44,515[Timer-0]WARN[com.mchange.v2.async.ThreadPoolAsynchronousRunner]-Taskcom.mchange.v2.resourcepool.BasicResourcePool$AcquireTask@98b13b(indeadlockedPoolThread)failedtocompleteinmaximumtime60000ms.Tryinginterrupt().2014-10-2415:35:51,937[com.mchange.v2.async.ThreadPoolAsynchronousRunner$PoolThread-#5]WARN[com.mchange.v2.resourcepool.BasicResourcePool]-com.mchange.v2.resourcepool.BasicResourcePool@1371566--Threadunexpectedlyinterruptedwhileperforminganacquisitionattempt.java.lang.InterruptedException:sleepinterrupted atjava.lang.Thread.sleep(NativeMethod) atcom.mchange.v2.resourcepool.BasicResourcePool$AcquireTask.run(BasicResourcePool.java:1805) atcom.mchange.v2.async.ThreadPoolAsynchronousRunner$PoolThread.run(ThreadPoolAsynchronousRunner.java:547)我的报错是因为部署的机器访问不到数据库，检查是否可以正常连接到数据库.
