本文提供了一个使用Java的HttpClient库进行POST请求提交表单数据的示例代码，展示了如何设置请求头、构建请求参数并发送到指定URL。

public class ToInterface {
    /**
     * post方式提交表单（模拟用户登录请求）
     */
    public static void postForm() {
        // 创建默认的httpClient实例.
        CloseableHttpClient httpclient = HttpClients.createDefault();
        // 创建httppost
        HttpPost httppost = new HttpPost("http://localhost:8000/send/sendWechatOrSMS");
        // 创建参数队列
        List<NameValuePair> formparams = new ArrayList<NameValuePair>();
        String string = "{\"userId\":\"0\",\"productType\":\"0\",\"feeName\":\"0\",\"accountType\":\"0\",\"account\":\"0\",\"feeTime\":\"0\",\"send_type\":\"0\",\"ordNo\":\"No201512270001\",\"orderType\":\"儿童口腔就医卡\",\"orderDate\":\"淘宝网\",\"template_code\":\"sl_qy_payment\",\"phone\":\"18618265268\"}";
        formparams.add(new BasicNameValuePair("string", string));
        UrlEncodedFormEntity uefEntity;
        try {
            uefEntity = new UrlEncodedFormEntity(formparams, "UTF-8");
            httppost.setEntity(uefEntity);
            System.out.println("executing request " + httppost.getURI());
            CloseableHttpResponse response = httpclient.execute(httppost);
            try {
                HttpEntity entity = response.getEntity();
                if (entity != null) {
                    System.out.println("--------------------------------------");
                    System.out.println("Response content: " + EntityUtils.toString(entity, "UTF-8"));
                    System.out.println("--------------------------------------");
                }
            } finally {
                response.close();
            }
        } catch (ClientProtocolException e) {
            e.printStackTrace();
        } catch (Exception e) {
            e.printStackTrace();
        } finally {
            // 关闭连接,释放资源
            try {
                httpclient.close();
            } catch (IOException e) {
                e.printStackTrace();
            }
        }
    }

    public static void main(String[] args) {
        postForm();
//        interfaceUtil("http://192.168.10.89:8080/eoffice-restful/resources/sys/oadata", "usercode=10012");
//        interfaceUtil("http://192.168.10.89:8080/eoffice-restful/resources/sys/oaholiday",
//                    "floor=first&year=2017&month=9&isLeader=N");
    }
