HTTP POST请求传参方式
方式一：

        String url = "http://xxxxxxx";
        logger.info("访问接口url: " + url);

        Map<String, String> paramsMap = new HashMap<>();
        paramsMap.put("name", "小明");
        paramsMap.put("age", 18);
        String paramJson = JSON.toJSONString(paramsMap);
        logger.info("json传参:" + paramJson);


        HttpHeaders headers = new HttpHeaders();
        headers.set("X-Access-token", token);
        logger.info("设置token:" + token);
        headers.setAccept(Collections.singletonList(MediaType.APPLICATION_JSON));
        logger.info("设置请求Accept格式:APPLICATION_JSON");
        headers.setContentType(MediaType.APPLICATION_JSON);
         logger.info("设置请求ContentType格式:APPLICATION_JSON");
        HttpEntity<String> request = new HttpEntity<String>(paramJson, headers);

        try {
            restTemplate.getMessageConverters().set(1, new StringHttpMessageConverter(StandardCharsets.UTF_8));

            response = restTemplate.postForEntity(url, request, Map.class);

            map = (Map<String, Object>) response.getBody();
            
            logger.info("获取请求接口返回信息:" + map);

            Map<String, Object> map_data = (Map<String, Object>) map.get("data");

方式二

        // 创建HttpClient对象
        CloseableHttpClient httpclient = HttpClients.createDefault();
        //http请求url
        HttpPost httpPost = new HttpPost("http://xxxx");
        // 模拟POST/PUT的body中数据，需转为JSON进行签名.
        Map<String, Object> dataMap = new HashMap<String, Object>();
        //POST请求参数
        //授权码
        dataMap.put("authorizationKey", "");
        //客户端IP
        dataMap.put("clientIp", "");
        //名称
        dataMap.put("name", "");
        //转为json传参
        String bodyParam = new Gson().toJson(dataMap);
        //设置编码
        StringEntity bodyData = new StringEntity(bodyParam, "UTF-8");
        httpPost.setEntity(bodyData);
        try {
            httpPost.setHeader("Content-type", "application/json");
            httpPost.setHeader("User-Agent", "Mozilla/4.0 (compatible; MSIE 5.0; Windows NT; DigExt)");
            String urlStr = httpPost.getURI().toString();
            // 公共参数URL
            httpPost.setURI(new URI(urlStr));
            //请求超时时间
            RequestConfig requestConfig = RequestConfig.custom().setConnectTimeout(5000)
                    .setConnectionRequestTimeout(5000).setSocketTimeout(5000).build();
            httpPost.setConfig(requestConfig);

            // 执行请求
            CloseableHttpResponse response = httpclient.execute(httpPost);
            // 取响应的结果
            int statusCode = response.getStatusLine().getStatusCode();
            if (statusCode == HttpStatus.SC_OK) {
                String resp = EntityUtils.toString(response.getEntity());
                //此处不同格式的返回信息 用不通方式的json去转
                //请看 https://blog.csdn.net/weixin_38193704/article/details/127402069?spm=1001.2014.3001.5502
                JSONArray jsonArray = (JSONArray) JSONArray.parse(resp);
                if (ObjectUtils.isNotEmpty(jsonArray)) {
                    JSONObject objectJson = jsonArray.getJSONObject(0);
                   System.out.println("获取返回值json信息" + objectJson);
                }
            }
        } catch (Exception e1) {
            e1.printStackTrace();

        }
