Spring Cron scheduler “disable pattern”

Question

My application loads some cron patterns from a properties file. I\'m using the @Scheduled annotation like this:

@Scheduled(cron = "${config.         


        

Answer 1

Per the Javadocs, as of Spring 5.1.0 the @Scheduled annotation can accept "-" as the cron expression to disable the cron trigger.

The special value "-" indicates a disabled cron trigger, primarily meant for externally specified values resolved by a ${...} placeholder.
