今天的需求是这样的，当工程师的任务完成之后会有一个短信提醒，so开始了调用阿里云短信发送API接口的征程。先试一下：

首先登陆阿里控制台：https://www.aliyun.com  ，接着找到短信服务（产品 -选项卡下面）

    点击-免费开通：

点击获取AK （阿里云访问秘钥）：

https://help.aliyun.com/document_detail/28637.html?spm=a2c4g.11174283.4.1.cCUFQw   快速创建RAM用户

在控制台完成申请签名和模板，获取调用接口必备的参数

在添加模板的时候，需要注意，模板的格式是有规则的，后面编写Java代码时需要进行匹配，举个栗子：

常规的Java或Java Web项目，导入如下两个jar包：

aliyun-java-sdk-core-3.3.1.jar 
aliyun-java-sdk-dysmsapi-1.0.0.jar

package cn.message;


import com.aliyuncs.DefaultAcsClient;

import com.aliyuncs.profile.DefaultProfile;
import com.aliyuncs.profile.IClientProfile;

    // 此处需要替换成开发者自己的AK(在阿里云访问控制台寻找)
    private static String accessKeyId = "accessKeyId";
