Springboot使用异步任务失败的问题

Springboot使用异步任务失败的问题

控制层代码

@RestController
@RequestMapping("novels")
public class NovelController {

    @Autowired
    private NovelService novelService;

    @PostMapping("all/{novelNameLike}")
    public DataProtocol getAllNovelUrl(@PathVariable String novelNameLike) throws ExecutionException, InterruptedException {

        novelNameLike = novelNameLike.trim();

        Future<Boolean> booleanFuture = novelService.insAllNovelAndChapter(novelNameLike);

        Boolean flag = booleanFuture.get();

        return flag ? new DataProtocol(CODE_SUCCESS, INSERT_SUCCESS, null) : new DataProtocol(CODE_ERROR, INSERT_FAILURE, null);
    }

}

业务层代码

@Service
public class NovelServiceImpl implements NovelService {

    @Autowired
    private HttpUtils httpUtils;

    @Autowired
    private ChapterMapper chapterMapper;

    @Autowired
    private NovelMapper novelMapper;

    @Override
    @Async
    @Transactional(propagation = Propagation.REQUIRED)
    public Future<Boolean> insAllNovelAndChapter(String novelNameLike) throws ExecutionException, InterruptedException {

        long start = System.currentTimeMillis();

        List<Novel> novels = parseAllNovel(novelNameLike);  //从工具类中获取全部的小说

        novelMapper.insAllNovel(novels);  //添加到数据可

        Future<List<List<Chapter>>> listFuture = httpUtils.getChapterList(novels); //从工具类中得到全部小说的全部章节网址

        List<List<Chapter>> chapterList = listFuture.get();

        for (List<Chapter> chapters : chapterList) {

            chapterMapper.insAllChapter(chapters);    //添加到数据库
        }

        long end = System.currentTimeMillis();

        System.err.println("业务层执行的时间：" + (end - start) + "ms");

        return new AsyncResult<>(true);
    }

}

工具类代码

@Component
public class HttpUtils {


    //用于爬取所有的小说的全部章节网址
    @Async
    public Future<List<List<Chapter>>> getChapterList(List<Novel> novels) {

        List<List<Chapter>> listArrayList = new ArrayList<>();

        long start = System.currentTimeMillis();

        for (Novel novel : novels) {

            String chapterUrl = novel.getChapterUrl();

            List<Chapter> chapters = parseCharacterUrl(chapterUrl);   //使用Jsoup爬取章节的类容

            listArrayList.add(chapters);

        }

        long end = System.currentTimeMillis();

        System.err.println("工具类执行的时间：" + (end - start) + "ms");

        return new AsyncResult<>(listArrayList);
    }

}

在控制台中输出的时间
工具类执行的时间：6748ms
业务层执行的时间：8898ms
页面响应时间：9140ms
没有使用异步任务前端的访问时间大概在：1200ms

好像异步任务失败了，这种应该怎么解决？

额，单体应用可以改成任务表驱动，分布式或者微服务改成MQ驱动，这样或许会好很多。
