I am using the following super class for my tasks that need to have access to request scope. Basically you can just extend it and implement your logic in onRun() method.

public abstract class RequestAwareRunnable implements Runnable {
  private final RequestAttributes requestAttributes;
  private Thread thread;

  public RequestAwareRunnable() {
    this.requestAttributes = RequestContextHolder.getRequestAttributes();
    this.thread = Thread.currentThread();
  }

  public void run() {
    try {
      RequestContextHolder.setRequestAttributes(requestAttributes);
      onRun();
    } finally {
      if (Thread.currentThread() != thread) {
        RequestContextHolder.resetRequestAttributes();
      }
      thread = null;
    }
  }

  protected abstract void onRun();
}
