Let me first declare that I am a beginner in quartz, but when integrating springboot, I found that it can be added to the database qrtz_cron_triggers and qrtz_job_details table by adjusting this new interface. I used druid to monitor and did not monitor the SQL statement. Is quartz operating the database itself? Is there a big god to help me
