Я использую Spring JDBCTemplate для выполнения операций SQL на источнике данных Apache Commons (org.apache.commons.dbcp.BasicDataSource), и когда служба работает и работает долго, я получаю это исключение:
org.springframework.dao.RecoverableDataAccessException: StatementCallback; SQL [SELECT * FROM vendor ORDER BY name]; The last packet successfully received from the server was 64,206,061 milliseconds ago. The last packet sent successfully to the server was 64,206,062 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.; nested exception is com.mysql.jdbc.exceptions.jdbc4.CommunicationsException: The last packet successfully received from the server was 64,206,061 milliseconds ago. The last packet sent successfully to the server was 64,206,062 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.

Я попытался добавить 'autoReconnect = true' в строку подключения, но эта проблема все еще возникает.Есть ли другой источник данных, который можно использовать для управления переподключением для меня?
