一、发送验证码工具类

import com.aliyuncs.dysmsapi.model.v20170525.SendSmsRequest;
import com.aliyuncs.dysmsapi.model.v20170525.SendSmsResponse;
import com.aliyuncs.exceptions.ClientException;
import com.aliyuncs.http.MethodType;
import com.aliyuncs.profile.DefaultProfile;
import com.aliyuncs.profile.IClientProfile;
import lombok.extern.slf4j.Slf4j;
@Slf4j

// 初始化ascClient需要的几个参数
// 初始化ascClient,暂时不支持多region（请勿修改）
IClientProfile profile = DefaultProfile.getProfile("cn-hangzhou", aliyun.getAliyunAccessKeyId(), aliyun.getAliyunAccessKeySecret());
DefaultProfile.addEndpoint("cn-hangzhou", "cn-hangzhou", "Dysmsapi", "dysmsapi.aliyuncs.com");
IAcsClient acsClient = new DefaultAcsClient(profile);
// 组装请求对象
SendSmsRequest request = new SendSmsRequest();
// 使用post提交
request.setMethod(MethodType.POST);
// 必填:待发送手机号。支持以逗号分隔的形式进行批量调用，批量上限为1000个手机号码,批量调用相对于单条调用及时性稍有延迟,验证码类型的短信推荐使用单条调用的方式
request.setPhoneNumbers(phone);
// 必填:短信签名-可在短信控制台中找到
request.setSignName(aliyun.getSignName());
// 必填:短信模板-可在短信控制台中找到
request.setTemplateCode(aliyun.getSmsCode());
// 可选:模板中的变量替换JSON串,如模板内容为"亲爱的${name},您的验证码为${code}"时,此处的值为
// 友情提示:如果JSON中需要带换行符,请参照标准的JSON协议对换行符的要求,比如短信内容中包含\r\n的情况在JSON中需要表示成\\r\\n,否则会导致JSON在服务端解析失败
request.setTemplateParam("{\"code\":\"{code}\",\"product\":\"城市数据运营\"}".replace("{code}", code));
// 可选-上行短信扩展码(扩展码字段控制在7位或以下，无特殊需求用户请忽略此字段)
// request.setSmsUpExtendCode("90997");
// 可选:outId为提供给业务方扩展字段,最终在短信回执消息中将此值带回给调用者
// request.setOutId("yourOutId");
// 请求失败这里会抛ClientException异常
SendSmsResponse sendSmsResponse = acsClient.getAcsResponse(request);
if (sendSmsResponse.getCode() != null && sendSmsResponse.getCode().equals("OK")) {
// 请求成功
log.debug(sendSmsResponse.getCode());
