public void testGet() throws Exception{
//创建CloseableHttpClient构造器
  CloseableHttpClient httpClient = HttpClients.createDefault();
//创建请求对象
  HttpGet httpGet = new HttpGet("http://localhost:8080");
//利用httpClient.execute(httpGet)发送请求
  CloseableHttpResponse response = httpClient.execute(httpGet);
//获取服务端返回的状态码
  int statusCode = response.getStatusLine().getStatusCode();
  System.out.println("statusCode");
//获取相应对象
  HttpEntity entity = response.getEntity();
  String body = EntityUtils.toString(entity);
  System.out.println("服务端返回的数据为： "+body);
//关闭资源
  response.close();
  httpClient.close();
