Charly :

I have the List of the requested user and I want to upload the list of the user every day at 7 pm on each day. how can i do that using Spring Boot.And yes, it should also check whether the list is available or not.

You can achieve this with @Scheduled annotation in one of your methods of the bean. In order to enable scheduling you need to put @EnableScheduling annotation in one of your config classes, can be the main class:

@SpringBootApplication
@EnableScheduling
public class TestingApplication {
    public static void main(String[] args) {
        SpringApplication.run(TestingApplication.class, args);
    }
}

Then you create a class, annotate it with @Component and create a method with @Scheduled annotation with a cron statement inside:

@Component
public class MyWorkerComponent {

    @Autowired
    private MyListChecker myListChecker;

    @Scheduled(cron = "0 0 19 * * ?")
    public void doTheListThingy() {
        if (myListChecker.isTheListAvailable()) {
            // your task logic
        }
    }
}
