Caused by: com.mchange.v2.resourcepool.TimeoutException: A client timed out while waiting to acquire a resource from com.mchange.v2.resourcepool.BasicResourcePool@1483de4 -- timeout at awaitAvailable()

把spring-dao.xml中

<property name="maxPoolSize" value="30"/>
改成

<property name="maxPoolSize" value="40"/>
運行正常，不拋出異常
再重新改回

<property name="maxPoolSize" value="30"/>
運行正常，沒有異常

有可能是多運行幾次，就不會有異常了？不能解決

解決辦法
將url加上autoReconnect=true&rewriteBatchedStatements=TRUE

jdbc.url=jdbc:mysql://127.0.0.1:3306/seckill?useUnicode=true&characterEncoding=utf8&autoReconnect=true&rewriteBatchedStatements=TRUE
