这两天在测试Hive权限控制代码Hamza，发现每天来的时候第一次老是会报出以下错误：

是连接出现问题了。原来mysql服务端会默认检查每个连接connection，一旦发现connection被闲置8小时（wait_timeout），便会被断开。那我们可以在连接字符串中加入autoReconnect=true，同时配置下mybatis，一段时间又默认执行下简单的查询，表明自己这个连接还活着，具体配置如下：
  1.     <environments default="development"> 

  2.        <environment id="development"> 

  3.            <transactionManager type="jdbc"/> 

  4.            <dataSource type="POOLED"> 

  5.                <property name="url" value="${cp.Url}"/>

  6.                <property name="driver" value="${cp.DriverClassName}"/>

  7.                <property name="username" value="${cp.Username}"/> 

  8.                <property name="password" value="${cp.Password}"/> 

  9.                <property name="poolPingEnabled" value="true"/>

  10.                <property name="poolPingQuery" value="select 1"/>

  11.                <property name="poolPingConnectionsNotUsedFor" value="3600000"/>

  12.            </dataSource> 

  13.        </environment> 

  14.     </environments>
