Spring TaskScheduler Bean not injected

I need to schedule a job when the a session is created. So I created my HttpSessionListener :

@Component
public class WebSessionListener implements HttpSessionListener {

//@Autowired
@Qualifier(value = "taskScheduler")
private ThreadPoolTaskScheduler taskScheduler;
@Autowired
private PanierService panierService;

//Notification that a session was created.
@Override
public void sessionCreated(HttpSessionEvent httpSessionCreatedEvent) {

    Runnable viderPanier20mnJob = PanierJobs.getViderPanier20mnJob(httpSessionCreatedEvent.getSession());
    taskScheduler.schedule(viderPanier20mnJob, PanierJobs.getNextDateTime());
    System.out.println("Session Created Called! -----------------------");
}

But my big problem here is that my TaskScheduler bean is not injected (NoSuchBeanDefinition or sometimes it just pops a NullPointerException).

Here is my TaskScheduler (taken from an example where it was working) :

@Configuration
@EnableScheduling
@EnableAsync
public class JobSchedulingConfig{

  @Bean
   public ThreadPoolTaskExecutor taskExecutor() {

        ThreadPoolTaskExecutor executor = new ThreadPoolTaskExecutor();
        return executor;
    }

    @Bean
    public ThreadPoolTaskScheduler taskScheduler() {

        ThreadPoolTaskScheduler scheduler = new ThreadPoolTaskScheduler();
        return scheduler;
    }
}
