quartz implements dynamic timing tasks

We often need scheduled tasks in development, such as regularly updating some information to organize, delete and other operations in documents. These situations can be implemented using @Scheduled scheduled tasks, but once the service is started, it cannot be modified (it is scheduled on the interface) Task) Then we need to deploy a dynamic scheduled […]
