emmm哪个呀 我看配置文件都没问题呀
哦，关键的是这一句
- com.mysql.jdbc.exceptions.jdbc4.CommunicationsException: The last packet successfully received from the server was 29,440,956 milliseconds ago. The last packet sent successfully to the server was 29,440,956 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.
连接超时什么的吧。不影响的话，无视就好。
