Answer 1

I would approach it in a way, that scheduled job runs always, but it does something only when the flag is set to true:

@Component
class ScheduledJob {

    private final AtomicBoolean enabled = new AtomicBoolean(false);

    @Scheduled(fixedRate = 1000)
    void execute() {
        if (enabled.get()) {
            // run spring batch here.
        }
    }

    void toggle() {
        enabled.set(!enabled.get());
    }

}

and a controller:

@RestController
class HelloController {

    private final ScheduledJob scheduledJob;

    // constructor

    @GetMapping("/launch")
    void toggle() {
        scheduledJob.toggle();
    }

}
