How to conditionally enable or disable scheduled jobs in Spring?

@Component
public class ImagesPurgeJob implements Job {

    private Logger logger = Logger.getLogger(this.getClass());

    @Value("${jobs.mediafiles.imagesPurgeJob.enable}")
    private boolean imagesPurgeJobEnable;

    @Override
    @Transactional(readOnly=true)
    @Scheduled(cron = "${jobs.mediafiles.imagesPurgeJob.schedule}")
    public void execute() {

         //Do something
        //can use DAO or other autowired beans here
        if(imagesPurgeJobEnable){

            Do your conditional job here...

        }
    }
}

The most efficient way to disable @Scheduled in Spring is to set cron expression to -

@Scheduled(cron = "-")
public void autoEvictAllCache() {
    LOGGER.info("Refresing the Cache Start :: " + new Date());
    activeMQUtility.sendToTopicCacheEviction("ALL");
    LOGGER.info("Refresing the Cache Complete :: " + new Date());
}

From the docs:

CRON_DISABLED

public static final String CRON_DISABLED
A special cron expression value that indicates a disabled trigger: "-". This is primarily meant for use with ${...} placeholders, allowing for external disabling of corresponding scheduled methods.

Since: 5.1 See Also: ScheduledTaskRegistrar.CRON_DISABLED

You can group schedule methods by conditions into number of services and init them like this:

@Service
@ConditionalOnProperty("yourConditionPropery")
public class SchedulingService {

@Scheduled
public void task1() {...}

@Scheduled
public void task2() {...}

}

Spring Boot provides @ConditionalOnProperty, which would be perfect if you were using Spring Boot. This annotation is a specialization of @Conditional, introduced with Spring 4.0.0.

Assuming you're just using "regular" spring and not Spring Boot, you could create your own Condition implementation for use with @Conditional that would mimic Spring Boot's @ConditionalOnProperty.
