AdvertiserListingTaskService.java

@Service
public class AdvertiserListingTaskService {
    
    public void executeWithConfig(TaskConfig config) {
        AdvertiserListingTask task = getTask();
        task.apply(config);
        task.run();  // Or something like executor.execute(task)
    }
    
    @Lookup
    public AdvertiserListingTask getTask() {
        return null;  // Spring will override this
    }
}

MessagesController.java

@Controller
@RequestMapping("/messages")
public class MessagesController {
    
    @Autowired
    private Map<String, AbstractTaskService> taskServicesByTaskName;
    
    @RequestMapping(/* POST */)
    public void process(@RequestBody Message message) {
        if (taskServicesByTaskName.containsKey(message.getTaskName())) {
            taskServicesByTaskName.get(
                    message.getTaskName()).executeWithConfig(
                            message.getConfig());
        }
    }
}

TaskConfig.java

@Configuration
public class TaskConfig {
    
    @Autowired
    private AdvertiserListingTaskService advertiserListingTaskService;
    
    @Bean
    public Map<String, AbstractTaskService> taskServicesByTaskName() {
        return Collections.unmodifiableMap(Steam.of(
                entry(AdvertiserListingTask.getName(), advertiserListingTaskService),
                entry(...),
                ...));
