二.Controller
post json 传参

/**
 * post    json传参
 * @param param
 * @return
 * @throws IOException
 */
@RequestMapping("aa")
public String Test(@RequestBody Map<String, String> param) throws IOException {

    //构建一个httpclient请求
    CloseableHttpClient httpClient = HttpClients.createDefault();
    CloseableHttpResponse response = null;
    try {
        //创建一个post请求
        HttpPost httpPost = new HttpPost("http://localhost:9910/hxdevice/device/list");
        //post请求传入json数据
        StringEntity se = new StringEntity(JSON.toJSONString(param), "utf-8");
        //设置请求的时候为application/json
        se.setContentType("application/json");
        //放入httppost中
        httpPost.setEntity(se);
        //调用请求方法
        response = httpClient.execute(httpPost);
        //判断返回结果
        if (response.getStatusLine().getStatusCode() == 200) {
            String content = EntityUtils.toString(response.getEntity(), "UTF-8");
            JSONObject jsonObject = JSONObject.parseObject(content);
            System.out.println(jsonObject);
        }
    } catch (IOException e) {
        e.printStackTrace();
    } catch (ParseException e) {
        e.printStackTrace();
    }

    return "成功";
}
post表单传参

/**

 * @return
 * @throws IOException
 */

@RequestMapping("bb")

    //构建一个httpclient请求

    try {
        //创建一个post请求
        HttpPost httpPost = new HttpPost("http://localhost:8080/test/qwe");
        List<NameValuePair> parameters = new ArrayList<NameValuePair>();
        for (Map.Entry<String, String> entry : param.entrySet()) {
            parameters.add(new BasicNameValuePair(entry.getKey(), entry.getValue()));
        }
        //post请求传入json数据
        formEntity = new UrlEncodedFormEntity(parameters,"UTF-8");
        //放入httppost中
        httpPost.setEntity(formEntity);
        //调用请求方法
        response = httpClient.execute(httpPost);
        //判断返回结果
        if (response.getStatusLine().getStatusCode() == 200) {
            String content = EntityUtils.toString(response.getEntity(), "UTF-8");
            System.out.println(content);
        }
    } catch (IOException e) {
