bug宝典JAVA篇 Caused by: org.quartz.JobPersistenceException: Couldn‘t store trigger

我将定时任务中改动了一个类的路径，结果服务器起来的时候出现这样的错误

org.springframework.context.ApplicationContextException: Failed to start bean ‘scheduler’; nested exception is org.springframework.scheduling.SchedulingException: Could not start Quartz Scheduler; nested exception is org.quartz.SchedulerConfigException: Failure occured during job recovery.

Caused by: java.lang.ClassNotFoundException: com.dzmsoft.fontal.worker.dto.ScheduleJob

从上面的日志可以看出com.dzmsoft.fontal.worker.dto.ScheduleJob这个是我以前的类路径，现在调整了位置，结果quartz就不认识，工程里面肯定不会有问题，那么推测只能出现在数据库层面。
查看qrtz_job_details
1
从BLOB中提取内容如下图所示，也就是说他吧一些东西记录在数据库中持久化了。
2
我至少删掉这些数据，再重新搞了。

delete from qrtz_cron_triggers;
delete from qrtz_triggers;
delete from qrtz_job_details;
