首先，我们要实现Java短信发送功能需要去申请第三方短信接口，以阿里云为例 点击跳转 
在API市场中找到短信验证码接口： 
我们可以先选择免费试用来测试： 
点击立即购买后可前往控制台查看： 
OK，一切就绪后我们开始测试使用。实现 首先我们先回到商品详情页，在商品详情页下面，说明了这个接口的短信调用地址以及请求参数等： 
接下来我们通过实例来调用接口进行测试： 1 、加入相关依赖 具体可参考：相关依赖

、发送验证码
public static void main(String[] args) {//短信api调用地址String host = "https://dfsns.market.alicloudapi.com";//请求路径String path = "/data/send_sms";//请求方式String method = "POST";//appcode：自己的短信AppCode，可以在自己的控制台找到，是一串32位的字符串String appcode = "14xfa0523x3s2fe8ep0u54te14c2w36ad";Map headers = new HashMap();//最后在header中的格式(中间是英文空格)为Authorization:APPCODE 83359fd73fe94948385f570e3c139105headers.put("Authorization", "APPCODE " + appcode);//根据API的要求，定义相对应的Content-Typeheaders.put("Content-Type", "application/x-www-form-urlencoded; charset=UTF-8");Map querys = new HashMap();Map bodys = new HashMap();//使用随机数生成4位验证码StringBuilder stringBuilder = new StringBuilder();for (int i = 0; i < 4; i++) {int randomNum = (int) (Math.random()*10);stringBuilder.append(randomNum);}String code = stringBuilder.toString();//这里是要发送给用户的验证码，我们使用了随机数进行生成bodys.put("content", "code:"+code);//这里是接受短信的手机号码，我们在实际开发时这里就不能写死了bodys.put("phone_number", "176****5321");//这里是发送短信的模板ID：代表整体短信文案模板bodys.put("template_id", "TPL_0000");try {HttpResponse response = HttpUtils.doPost(host, path, method, headers, querys, bodys);System.out.println(response.toString());//获取response的bodySystem.out.println(EntityUtils.toString(response.getEntity()));} catch (Exception e) {e.printStackTrace();}} 好的大功告成，我们可以看下控制台给我们的打印： 
说明发送成功了。我们打开手机也可以看到发给我们的发送验证码
