Let’s take a look at the example below: Output: There is one thread, scheduling-1, that handles both task1 and task2. The moment task1 g...
We can always keep the cronexpression in a property file using Spring Config. If the Spring Config server is not available, we can also fetch it from the database. Any update of the cronexpression will update the scheduler. But in order to cancel the current schedule and execute the new schedule, we can expose an APIto refresh the cronjob: Addition...
