Spring Cron scheduler “disable pattern”

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

Per the Javadocs:

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

If you're stuck pre Spring 5.1.0 (SpringBoot < 2.1), your only option may be to disable the bean/service with the @Scheduled method altogether, for example by using a @ConditionalOnProperty("my.scheduleproperty.active") annotation and not setting the property (or setting it to false)

If it was a cron expression (NOT spring scheduler), you could have used below which makes the cron run on 2099

59 59 23 31 12 ? 2099

But spring scheduler does not take a year as input. This is what I have found to defer it for some extended period. Below will run on 29 Feb which will be a leap year.
