Java 多线程请求数据，解决for循环多次接口问题

 ExecutorService exe = Executors.newFixedThreadPool(20);
exe.execute(new Runnable() {
                                @Override
                                public void run() {
                                    qingqiujiekou(finalGoodsCollect,goodsDetails);
                                }
                            });
exe.shutdown();
        while (true) {
            if (exe.isTerminated()) {
                System.out.println("结束了！");
                break;
            }
            try {
                Thread.sleep(200);
            } catch (InterruptedException e) {
                e.printStackTrace();
            }
        }
    public void qingqiujiekou(GoodsCollect goodsCollect, String goodsDetails){
        //耗时方法，如请求接口
    }
