As you can see, when we use mysql version 5.1.13, there will be an error that the have_query_cache parameter is missing. This will disappear after upgrading to 8.x. However, in our company, the mysql version has been fixed to 5.1.13 and cannot be easily upgraded, otherwise business production problems will occur.
### What You Expected?
We hope that the community can solve this parameter problem and be compatible with the java connector of the lower version of mysql 5.1.x
