If you want to use Java Config you will need to create configuration implementing SchedulingConfigurer

@EnableScheduling
@Configuration
class SchedulingConfiguration implements SchedulingConfigurer {
    private final Logger logger = LoggerFactory.getLogger(getClass());
    private final ThreadPoolTaskScheduler taskScheduler;

    SchedulingConfiguration() {
        taskScheduler = new ThreadPoolTaskScheduler();
        taskScheduler.setErrorHandler(t -> logger.error("Exception in @Scheduled task. ", t));
        taskScheduler.setThreadNamePrefix("@scheduled-");

        taskScheduler.initialize();
    }

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

You can modify error handler for your needs. Here I only log a message.

Don't forget to call taskScheduler.initialize();. Without it you'll get:

java.lang.IllegalStateException: ThreadPoolTaskScheduler not initialized
