如果程序不重启，到第二天就会报这个错，根据网上说的，调整mysql的连接时间，我们数据库连接的mycat，mysql的间隔时间已经调整到了24个小时，还是报错：

我的连接池信息：
<environment id="cybatis">
type="JDBC" 代表使用JDBC的提交和回滚来管理事务
<transactionManager type="JDBC" />
mybatis提供了3种数据源类型，分别是：POOLED,UNPOOLED,JNDI
POOLED 表示支持JDBC数据源连接池
UNPOOLED 表示不支持数据源连接池
JNDI 表示支持外部数据源连接池
<dataSource type="POOLED">
<dataSource type="com.asiainfo.send.utils.druidUtils.DruidDataSourceFactory">
<property name="driver" value="${jdbc.driver}" />
<property name="url" value="${jdbc.url}" />
<property name="username" value="${jdbc.username}" />
<property name="password" value="${jdbc.password}" />
<property name="poolPingEnabled" value="true"/>
<property name="poolPingQuery" value="select 1"/>
<property name="poolPingConnectionsNotUsedFor" value="3600000"/>
</dataSource>
</environment>
看了mysql的驱动的源码，还是没有找到原因，但是当我将mybatis默认的连接池POOLED换成HIKARICP的连接池后，从9月6日下午18:10:02 到9月9日10点都没有再包上面的错，
更换数据源的方式请看 ： https://blog.csdn.net/fhf2424045058/article/details/100558976
