近期调用企业接口 遇到问题，jdk1.7可以发送成功，jdk1.8发送不了请求

发送post方法：
public static String doPost(String url, String params) throws Exception {
        
        CloseableHttpClient httpclient = HttpClients.createDefault();
        HttpPost httpPost = new HttpPost(url);// 创建httpPost   
        httpPost.setHeader("Accept", "application/json"); 
        httpPost.setHeader("Content-Type", "application/json");
        String charSet = "UTF-8";
        StringEntity entity = new StringEntity(params, charSet);
        httpPost.setEntity(entity);        
        CloseableHttpResponse response = null;
        
        try {
            
            response = httpclient.execute(httpPost);
            StatusLine status = response.getStatusLine();
            int state = status.getStatusCode();
            if (state == HttpStatus.SC_OK) {
                HttpEntity responseEntity = response.getEntity();
                String jsonString = EntityUtils.toString(responseEntity);
                return jsonString;
            }
            else{
                // logger.error("请求返回:"+state+"("+url+")");
            }
        }
        finally {
            if (response != null) {
                try {
                    response.close();
                } catch (IOException e) {
                    e.printStackTrace();
                }
            }
            try {
                httpclient.close();
            } catch (IOException e) {
                e.printStackTrace();
            }
        }
        return null;
    }
