1：如果空闲时间很长导致mysql报错：
Caused by: com.mysql.jdbc.exceptions.jdbc4.CommunicationsException: The last packet successfully received from the server was 120,994,249 milliseconds ago. The last packet sent successfully to the server was 120,994,249 milliseconds ago. is longer than the server configured value of ‘wait_timeout‘. You should consider either expiring and/or testing connection validity before use in your application, increasing the server configured values for client timeouts, or using the Connector/J connection property ‘autoReconnect=true‘ to avoid this problem.
解决办法：在mysql的配置文件中my.ini
[mysqld] wait_timeout=1814400 interactive_timeout=1814400
