Java线程处理Future

        ExecutorService service = Executors.newCachedThreadPool();
        Future future = service.submit(new Callable() {
            @Override
            public Result call() {
                MMService mmService = new MMService();

                return mmService.userManage(userData);
            }
        });

        Result result = null;
        try {
            result = future.get(30, TimeUnit.SECONDS);
        } catch (InterruptedException e) {
            e.printStackTrace();
        } catch (ExecutionException e) {
            e.printStackTrace();
        } catch (TimeoutException e) {
            e.printStackTrace();
        } finally {
            service.shutdown();
        }
