一、阿里云短信服务

进入阿里云平台，然后选择短信服务，通过API发送短信(需要充值金额，几块钱就可以，我们仅仅是小规模项目)

找到openAPI

可以看到Java语言的代码模板，这个就是Java SendSMS短信服务的代码

创建Accesskey

 创建完成后

创建用户

添加权限

添加签名和模板

二、后端代码部分

pom.xml文件中下载依赖

<!--        阿里云第三方依赖-->
        <dependency>
            <groupId>com.aliyun</groupId>
            <artifactId>aliyun-java-sdk-core</artifactId>
            <version>4.5.0</version>
        </dependency>

配置文件中配置参数

aliyun.accessKeyID=用自己的!!!
aliyun.accessSecret=用自己的！！！
