Spring scheduler which is run after application is started and after midnight

cron, scheduling, spring

Solution

I would do this with two separate constructs.

For after the application starts, use `@PostConstuct`, and for every night at midnight use `@Scheduled` with the `cron` value set. Both are applied to a method.

public class MyClass {
    @PostConstruct
    public void onStartup() {
        doWork();
    }

    @Scheduled(cron="0 0 0 * * ?")
    public void onSchedule() {
        doWork();
    }

    public void doWork() {
        // your work required on startup and at midnight
    }
}

Problem
