Using @Bean annotated method will do the trick. But as SpringBoot only going to call this method 1 time, and return cached version after that, you will need to restart Spring to getting new value.

To get new run time from database, using SchedulingConfigurer:

@Configuration
public class SchedulerConfig implements SchedulingConfigurer {

    @Autowired
    private YourService yourService;

    @Bean
    public YourJob yourJob() {
        return new YourJob();
    }

    @Override
    public void configureTasks(ScheduledTaskRegistrar taskRegistrar) {
        taskRegistrar.addTriggerTask(
                () -> yourJob().performJob(),
                (TriggerContext triggerContext) -> yourService.getCron()
        );
    }

}

Note: don't use @Scheduled with this way.
