Using Spring's @Scheduled annotation with a specific executor

The Javadoc of @EnableScheduling is pretty exhaustive in that area.

You need to implement a SchedulingConfigurer to fine-tune which Executor needs to be used.

@Configuration
@EnableScheduling
public class AppConfig implements SchedulingConfigurer {

 @Override
 public void configureTasks(ScheduledTaskRegistrar taskRegistrar) {
  taskRegistrar.setScheduler(taskScheduler());
 }

 @Bean
 public Executor taskScheduler() {
  ThreadPoolTaskScheduler t = new ThreadPoolTaskScheduler();
  t.setPoolSize(2);
  t.setThreadNamePrefix("taskScheduler - ");
  t.initialize();
  return t;
 }


}

Executor qualification with @Scheduled is not supported yet.
