Java怎样实现短信发送与接收呢？

 //官网的URL
        String url="http://gw.api.taobao.com/router/rest";
        //成为开发者，创建应用后系统自动生成
        String appkey="23300902";
        String secret="24c5befb62bed7917bf139b7d39d251d";
        //短信模板的内容
        String json="{\"code\":\"1234\",\"product\":\"某某电子商务验证\"}";
        TaobaoClient client = new DefaultTaobaoClient(url, appkey, secret);
        AlibabaAliqinFcSmsNumSendRequest req = new AlibabaAliqinFcSmsNumSendRequest();
        req.setExtend("123456");
        req.setSmsType("normal");
        req.setSmsFreeSignName("变更验证");
        req.setSmsParamString(json);
        req.setRecNum(tel);
        req.setSmsTemplateCode("SMS_4720619");
        try {
            AlibabaAliqinFcSmsNumSendResponse rsp = client.execute(req);
            System.out.println(rsp.getBody());
            return 1;
        } catch (Exception e) {
            // TODO: handle exception
            return -1;
        }
