Flink cdc代码的方式结合mybatis读mysql运行一段时间报连接数据库超时的问题怎么解决

请教大佬们，Flink cdc代码的方式结合mybatis读mysql运行一段时间总是报连接数据库超时的问题： org.apache.ibatis.exceptions.PersistenceException:

Error querying database. Cause: com.mysql.cj.jdbc.exceptions.CommunicationsException: The last packet successfully received from the server was 94,894,842 milliseconds ago. The last packet sent successfully to the server was 94,894,842 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.
