java 线程池 newFixedThreadPool 返回

线程池不自带结果返回，需要手动需要添加  使用到 Callable  Future 

public static ExecutorService fixedThreadPool = Executors.newFixedThreadPool(5);

 

　　Callable myCallable = new Callable() {
            @Override
            public Object call() throws Exception {
                String fileLink = "http://106.14.117.71/recordings/2020-04-26/2020-04-26-09-50-19-5134_015979792476_999888.wav";
                Object response = Rules.AsrRecognition("02188557706", fileLink);
//                responseQuery.offer(response);
                Thread.sleep(2000);
                System.out.println(response);
                return response;
            }
        };
        Future future = fixedThreadPool.submit(myCallable);
        System.out.println("获取返回值: "+future.get());

@Bean //运行时启动
public void FilesMonitor() throws Exception {
    String rootDir = "E:\\javakf";
    // 轮询间隔 5 秒
    long interval = TimeUnit.SECONDS.toMillis(1);
    // 创建过滤器
    IOFileFilter directories = FileFilterUtils.and(
            FileFilterUtils.directoryFileFilter(),
            HiddenFileFilter.VISIBLE);
    IOFileFilter files = FileFilterUtils.and(
            FileFilterUtils.fileFileFilter(),
            FileFilterUtils.suffixFileFilter(".txt"));
    IOFileFilter filter = FileFilterUtils.or(directories, files);
    // 使用过滤器
    FileAlterationObserver observer = new FileAlterationObserver(new File(rootDir), filter);
    //不使用过滤器
    //FileAlterationObserver observer = new FileAlterationObserver(new File(rootDir));
    observer.addListener(new FilesMonitor());
    //创建文件变化监听器
    FileAlterationMonitor monitor = new FileAlterationMonitor(interval, observer);
    // 开始监控
    monitor.start();
