Spring boot 发送手机验证码

由于阿里云现在的短信签名无法通过申请，所以我这里选择了中国网建SMS短信平台（手机号注册即用，有免费赠送的几条短信测试）

demo代码地址：https://github.com/mer97/springboot-sendmessage

Spring boot 实现发送手机验证码功能：

依赖包：

dependencies {
    implementation 'org.springframework.boot:spring-boot-starter-json'
    implementation 'org.springframework.boot:spring-boot-starter-data-redis'
    implementation 'commons-httpclient:commons-httpclient:3.0.1'
    implementation 'commons-codec:commons-codec:1.4'
    testImplementation 'org.springframework.boot:spring-boot-starter-test'
}

工具类：

import org.apache.commons.httpclient.Header;
import org.apache.commons.httpclient.HttpClient;
import org.apache.commons.httpclient.NameValuePair;
import org.apache.commons.httpclient.methods.PostMethod;

    public static Integer send(String Uid,String Key,String sendPhoneNum,String desc){

        HttpClient client = new HttpClient();
        PostMethod post = new PostMethod(SMS_Url);
        post.addRequestHeader("Content-Type","application/x-www-form-urlencoded;charset=gbk");// 在头文件中设置转码

        //设置参数

                new NameValuePair("smsText", desc)
        };

        post.setRequestBody(data);

        try {
            client.executeMethod(post);
        } catch (Exception e) {  e.printStackTrace();  }

        } catch (Exception e) {  e.printStackTrace();  }

        post.releaseConnection();

        return Integer.parseInt(result);
