@EnableScheduling is annotated on class level to configure class for scheduling jobs in Spring.
This annotation is used along with @configuration for configuring scheduler inside the class as method. 

@Configuration   @EnableScheduling //to enable scheduling in class public class MyScheduler{         //Custom Code   }

@Scheduler

@Scheduler is used on the method level to run method at scheduled time. The annotation takes parameter to configure time for scheduling. This can be done using cron expression or using delay functions provided in spring.

//annotate with scheduler   @Scheduled(cron="*/2 * * * * *")//for every 2 seconds   public void jobForScheduler() {         //Custom Code to execute every 2 seconds   }
