HttpClient 通过 httpPost发送数据模板

 　　　　String url = "";
        CloseableHttpClient httpClient = HttpClientBuilder.create().build();
        HttpPost httpPost = new HttpPost(url);
        StringEntity stringEntity = new StringEntity(JSON.toJSONString(data), "UTF-8");
        httpPost.setEntity(stringEntity);
        httpPost.setHeader("Content-Type", "application/json;charset=utf8");
        CloseableHttpResponse response = null;
        try {
            // 由客户端执行(发送)Post请求
            response = httpClient.execute(httpPost);
            // 从响应模型中获取响应实体
            HttpEntity responseEntity = response.getEntity();
            if (responseEntity != null) {
                log.info("响应内容:" + EntityUtils.toString(responseEntity));
            }
        } catch (IOException e) {
            e.printStackTrace();
        } finally {
            try {
                // 释放资源
                if (httpClient != null) {
                    httpClient.close();
                }
                if (response != null) {
                    response.close();
                }
            } catch (IOException e) {
                e.printStackTrace();
            }
