自定义方法 模拟高并发场景，对方法进行测试

 @ApiOperation("test")    @PostMapping("test")    @ResponseBody    public String test() { int count = 200; String url = "http://localhost:8080/newrank/getNewRankCityInfo"; CountDownLatch latch = new CountDownLatch(count); for (int i = 0; i < count; i++) {     int finalI = i;     new Thread() {  @Override  public void run() {      try {   latch.await();   //在此处执行要调用的接口   String response = HttpRequestUtil.connect(url)    .header("Content-Type", "application/json")    .charset("utf-8")    .timeout(5000)    .post()    .html();   if (StringUtils.isNotBlank(response)) {BaseResponse<NewRankCityInfoResp> newRankCityInfoRespBaseResponse = JSON.parseObject(response, new TypeReference<BaseResponse<NewRankCityInfoResp>>() {});System.out.println(JSON.toJSONString(newRankCityInfoRespBaseResponse) + "ok_" + finalI);   }      } catch (Exception e) {      }  }     }.start();//每循环一次，就启动一个新的线程     latch.countDown();//每启动一个新的线程，count-- } return "ok";    }
