如何使解析器异步运行

Question

我正在建立基于Java的graphQl App，并发现graphql-java-tools确实方便了问题，尽管很简单 使用graphql-java使字段解析器异步，我找不到使用graphql-java-tools的方法

我尝试了

@Bean
    public ExecutionStrategy executionStrategy() {
        return new AsyncExecutionStrategy();
    }

这里是我用来测试的解析器

@Component
public class VideoResolver  implements GraphQLResolver<Video> {


     public Episode getEpisode(Video video){

        Episode result = new Episode();

        result.setTitle("episodeTitle");
        result.setUuid("EpisodeUuid");
        result.setBrand("episodeBrand");
        try {
            Thread.sleep(2000L);
            System.out.println(Thread.currentThread().getName());
        } catch (InterruptedException e) {
            e.printStackTrace();
        }
        return result;
    }

    public List<Images> getImages(Video video){

        Images image = new Images();
        image.setFileName("Image FileName1");
        List<Images> imageList = new ArrayList<>();
        imageList.add(image);

        try {
            Thread.sleep(2000L);
            System.out.println(Thread.currentThread().getName());
        } catch (InterruptedException e) {

            System.out.println("Exxxxxxxxxx");
        }
        return imageList;
    }
}

假设这应该在大约2秒钟内运行并打印两个不同的流，但是没有花费4 并全部打印在同一流中
