### Error querying database. Cause: org.apache.ibatis.transaction.TransactionException: Error configuring AutoCommit. Your driver may not support getAutoCommit() or setAutoCommit(). Requested setting: false. Cause: com.mysql.jdbc.exceptions.jdbc4.CommunicationsException: The last packet successfully received from the server was 163,618,589 milliseconds ago. The last packet sent successfully to the server was 163,618,589 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.
### The error may exist in org/apache/submarine/database/mappers/SysUserMapper.xml
### The error may involve org.apache.submarine.server.workbench.database.mappers.SysUserMapper.login
