[08S01] Communications link failure

The last packet sent successfully to the server was 0 milliseconds ago. The driver has not received any packets from the server. Communications link failure  

The last packet sent successfully to the server was 0 milliseconds ago. The driver has not received any packets from the server.

原因分析:

1、端口被防火墙了

2、MySQL服务在长时间不连接之后断开了,断开之后的首次请求会抛出这个异常。
