本文介绍了一种使用Java实现短信服务的方法，包括实体类设计、发送短信的代码逻辑及异常处理等。

首先介绍发送短信是个什么鬼？

说白了就是一个短信服务器提供一个webservice服务供我们调用。我用到是一个提供了sendSms（String phone，String content）的方法。

下面开始唠干的，

首先我创建了一个实体类SmsConst来存放一些常量。如图所示：

实体类创建完毕之后上代码：

public class SmsTest {


   public static String sendSms(String mobiles,String msg) {
       if(mobiles!=null){
           if(mobiles.contains(",")){
               int len = mobiles.split(",").length;
               if(len > 500){
                   return SmsConst.RSLTCODE_PHONE_FIVE_HUNDRED;
               }
           }else{
               if(!isMobile(mobiles)){
                   return SmsConst.RSLTCODE_PHONE_ERROR;
               }
           }
       }
       if(msg == null || msg.equals("")){//短信为空时，不允许发送
           return SmsConst.RSLTCODE_CONTENT_EMPTY;
       }else{       //   短信内容为空格时，不允许发送
           String nmsg = msg.replace(" ", "").replace(" ", "");
           if(nmsg.length() == 0){
               return SmsConst.RSLTCODE_CONTENT_BLANK;
           }
       }

       CloseableHttpClient hc = HttpClientBuilder.create().build();
       HttpPost httpPost = null;
       CloseableHttpResponse response = null;
       try {

           RequestConfig requestConfig = RequestConfig.custom()
                    .setConnectionRequestTimeout(5000).setConnectTimeout(5000)
                    .setSocketTimeout(5000).build();

           httpPost = new HttpPost(SmsConst.SEND_SMS_URL);
           httpPost.setConfig(requestConfig);

           List<NameValuePair> nvps = new ArrayList<NameValuePair>();
            nvps.add(new BasicNameValuePair("strmobile", mobiles));
            nvps.add(new BasicNameValuePair("bstrMsg", msg));

            httpPost.setEntity(new UrlEncodedFormEntity(nvps,"utf-8"));

           response = hc.execute(httpPost);
           if (response.getStatusLine().getStatusCode() >= 400) {
               Logger.log("return code is:"+response.getStatusLine().getStatusCode());
               return null;
           }
           HttpEntity entity = response.getEntity();
           if (entity != null) {
               String body = EntityUtils.toString(entity);
               Logger.log(httpPost.getURI()+" RES: "+body);
               body=readerDOMParseXML(body);
               return body;
           } else {
               Logger.log("response is null:");
               return SmsConst.RSLTCODE_NO_DATA_ACCEPT;
           }
       } catch (Exception e) {
           Logger.log(e.getMessage());
           return SmsConst.RSLTCODE_SMS_FUNCTION_ERROR;
       } finally {
           try {
               httpPost.abort();
               response.close();
           } catch (Exception e) {
               httpPost=null;
               response=null;
               Logger.log(e.getMessage());
           }
       }
   }
   public static String readerDOMParseXML(String xml) throws Exception {
        DocumentBuilderFactory buildFactory = DocumentBuilderFactory.newInstance();
        DocumentBuilder documentBuilder = buildFactory.newDocumentBuilder();
        ByteArrayInputStream bisxml = new ByteArrayInputStream(xml.getBytes());
        Document document = documentBuilder.parse(bisxml);
        bisxml.close();//the xml data have load in memory
        Element node = document.getDocumentElement();
        NodeList nodelist = node.getChildNodes();
        for (int i = 0; i < nodelist.getLength(); i++)
            System.out.println(nodelist.item(i).getNodeName() + "===DOM===>" + nodelist.item(i).getTextContent());
        return nodelist.item(0).getTextContent();
   }
   /**
   * 手机号验证
   *
   * @param str
   * @return 验证通过返回true
   */
   public static boolean isMobile(String str) {
       Pattern p = null;
       Matcher m = null;
       boolean b = false;
       p = Pattern.compile("^[1][3,4,5,7,8][0-9]{9}$"); // 验证手机号
       m = p.matcher(str);
       b = m.matches();
       return b;
   }
