Execute Task Everyday at Midnight - Grails 3.2.2

Question

I have a method like MyController.foo() and I want to execute it every day at 00:00.

I have seen some solutions that use a TimerTask with a 1 day delay in seconds, but the day of time change it will bring some errors.

So ... What is the most efficient way to achieve this?

Answer 1

First you need to enable scheduling using spring boot annotation:

@EnableScheduling
class Application extends GrailsAutoConfiguration {
    static void main(String[] args) {
        GrailsApp.run(Application, args)
    }
}

Then you can put @Scheduled annotation on your methods:

@Scheduled(cron="00 00 * * *")
def foo() {
    //do something
}

Cron expression 00 00 * * * means execute every midnigth.
