@Configuration
public class ScheduleConfig implements SchedulingConfigurer {
    @Override
    public void configureTasks(ScheduledTaskRegistrar taskRegistrar) {
        Method[] methods = BatchProperties.Job.class.getMethods();
        int defaultPoolSize = 10;
        int corePoolSize = 0;
        if (methods != null && methods.length > 0) {
            for (Method method : methods) {
                Scheduled annotation = method.getAnnotation(Scheduled.class);
                if (annotation != null) {
                    corePoolSize++;
                }
            }
            if (defaultPoolSize > corePoolSize)
                corePoolSize = defaultPoolSize;
        }
        taskRegistrar.setScheduler(Executors.newScheduledThreadPool(corePoolSize));
    }
}

@Configuration
public class ScheduleConfig implements SchedulingConfigurer {
    @Override
    public void configureTasks(ScheduledTaskRegistrar taskRegistrar) {
        Method[] methods = BatchProperties.Job.class.getMethods();
        int defaultPoolSize = 10;
        int corePoolSize = 0;
        if (methods != null && methods.length > 0) {
            for (Method method : methods) {
                Scheduled annotation = method.getAnnotation(Scheduled.class);
                if (annotation != null) {
                    corePoolSize++;
                }
            }
            if (defaultPoolSize > corePoolSize)
                corePoolSize = defaultPoolSize;
        }
        taskRegistrar.setScheduler(Executors.newScheduledThreadPool(corePoolSize));
    }
}
