1. 开通aliyun上的短信服务，主要得到

（1）访问秘钥 accessKeyId <==>AccessKeySecret
（2）短信签名+模板code
参考官方文档

2. API测试短信发送：

参考官方文档
（1）下载sdk （原版）

        <dependency>
            <groupId>com.aliyun</groupId>
            <artifactId>aliyun-java-sdk-core</artifactId>
            <version>4.5.3</version>
        </dependency>

（2） 测试

import com.aliyuncs.CommonResponse;

import com.aliyuncs.IAcsClient;
import com.aliyuncs.exceptions.ClientException;

import com.aliyuncs.profile.DefaultProfile;

    public  void sendSms( ) {

        DefaultProfile profile = DefaultProfile.getProfile("cn-hangzhou", accessKeyId, accessKeySecret); 
        IAcsClient client = new DefaultAcsClient(profile);
        // 2. 组装请求对象

        }
    }
