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.
