java语言实现的短信接入实例，各公司大同小异

和几家短信平台接触过，都进行了接入测试。总体来说短信发送又快，覆盖率又全的，价格相对贵些。简易选两家分开使用，短信验证码的用一家贵的快的，普通的推广群发短信就用一个便宜的。

下面显示下测试代码

 public class HttpSMSSender {

     protected final Logger logger = LoggerFactory.getLogger(getClass());

     // 短信接口地址
     private String postUrl = "http://ip:port/webservice.asmx";
     @Autowired
     private AppVars vars;

     private String sname = "username"; // 提交账户
     private String spwd = "password"; // 提交账户的密码

     private String spnumber = ""; // 企业代码（扩展号，可空着）
     private String key = "【某某公司】";

     @Deprecated
     String sdst; // 接收号码，每次只能提交1个号码
     @Deprecated
     String smsg; // 信息内容,通常为70汉字以内，具体由平台内部决定

     /**
      * @param phoneNum
      *            手机号码
      * @param msg

      * @return 成功返回0
