数据库连接池 连接超时问题

The last packet successfully received from the server was 314,213 milliseconds ago. The last packet sent successfully to the server was 0 milliseconds ago.; nested exception is com.mysql.jdbc.exceptions.jdbc4.CommunicationsException: Communications link failure

日志报错信息：数据库连接异常，出现了超时的错误。

1、在JDBC url里配置了autoReconnect 属性，结果也未解决问题 ;autoReconnect=true;failOverReadOnly=false;
