1、这里默认你已经开通了阿里云短信服务
SendSms_短信服务_API调试-阿里云OpenAPI开发者门户
2、pom.xml引入依赖
<!-- 阿里云短信依赖--><dependency><groupId>com.aliyun</groupId><artifactId>aliyun-java-sdk-core</artifactId><version>4.5.16</version></dependency><!-- fastjson2依赖 --><dependency><groupId>com.alibaba.fastjson2</groupId><artifactId>fastjson2</artifactId><version>2.0.24</version></dependency><!-- redisson依赖 --><dependency><groupId>org.redisson</groupId><artifactId>redisson</artifactId><version>3.13.6</version></dependency>

3、新建工具类，生成6个随机数，新建package名util，类名RandomUtil
package com.xxxx.util;import java.text.DecimalFormat;import java.util.*;/*** 随机数生成 工具类*/public class RandomUtil {private static final DecimalFormat sixdf = new DecimalFormat("000000");/*** 生成6个随机数* @return*/public static String getSixBitRandom() {return sixdf.format(random.nextInt(1000000));}}
4.新建工具类，发送阿里云验证码，类名为：SendSmsUtil
package com.xxxx.util;import com.alibaba.fastjson2.JSONObject;import monRequest;import monResponse;import com.aliyuncs.DefaultAcsClient;import com.aliyuncs.IAcsClient;import com.aliyuncs.http.MethodType;import com.aliyuncs.profile.DefaultProfile;import org.apache.ibatis.reflection.ExceptionUtil;import java.util.Map;/*** 阿里云 发生 短信验证码 工具类* mobile 手机号码* param 验证码6位随机数*/public class SendSmsUtil {public static boolean sendCode(String mobile, Map<String, String> param) {DefaultProfile profile = DefaultProfile.getProfile("default", "您的 AccessKey ID", "必填，您的 AccessKey Secret");IAcsClient client = new DefaultAcsClient(profile);//设置相关固定的参数CommonRequest request = new CommonRequest();request.setMethod(MethodType.POST);request.setDomain("");request.setVersion("-05-25");request.setAction("SendSms");//设置发送相关的参数request.putQueryParameter("PhoneNumbers", mobile); //手机号request.putQueryParameter("SignName","签名名称"); //申请阿里云 签名名称request.putQueryParameter("TemplateCode","模板code"); //申请阿里云 模板coderequest.putQueryParameter("TemplateParam", JSONObject.toJSONString(param));//验证码数据，转换json数据传递try {//最终发送CommonResponse response = client.getCommonResponse(request);boolean success = response.getHttpResponse().isSuccess();return success;} catch (Exception e) {e.printStackTrace();System.out.println(e);System.out.println(ExceptionUtil.unwrapThrowable(e));System.out.println(e.getMessage());return false;}}}
5、user控制层
package com.xxxx.controller;/*** user用户控制器*/@RestController@Validatedpublic class UserController {@AutowiredRedissonService redissonService;/*** 验证手机号 发生验证码*/@PostMapping("/user/send")public ApiRestResponse sendCode(@NotBlank(message = "手机号不能为空") @Pattern(regexp = "^[1][3,4,5,6,7,8,9][0-9]{9}$", message = "手机号格式有误") String mobile) {//生成6位随机验证码String code = RandomUtil.getSixBitRandom();//保存验证码到redisBoolean isExist = redissonService.saveCodeToRedis(mobile, code);if(!isExist) {//阻止重复获取验证码return ApiRestResponse.error(400,"您已获取过验证码了");}//转成HashMapMap<String, String> param = new HashMap<>();param.put("code", code);//发送验证码boolean res = SendSmsUtil.sendCode(mobile, param);if(!res) {return ApiRestResponse.success("短信验证码发送失败");}return ApiRestResponse.success("短信验证码发送成功");}}
6、redisson服务层 保存和验证code值
package com.xxxx.service.impl;import com.xxxx.service.RedissonService;import org.redisson.Redisson;import org.redisson.api.RBucket;import org.redisson.api.RedissonClient;import org.springframework.stereotype.Service;import java.util.concurrent.TimeUnit;@Servicepublic class RedissonServiceImpl implements RedissonService {/*** 把手机号 和 验证码 保存到 redisson去* @param mobile* @param code* @return*/@Overridepublic Boolean saveCodeToRedis(String mobile, String code) {RedissonClient client = Redisson.create();//通过手机号 检索是否已存在RBucket<String> bucket = client.getBucket(mobile);boolean exists = bucket.isExists();if(!exists) {//如果不存在 说明是第一次放进去的 往redis set设置值bucket.set(code, 60, TimeUnit.SECONDS);//返回true 表示存储成功 在60秒内 这个值一直存在，避免用户重复获取验证码return true;}return false;}}
package com.xxxx.service;public interface RedissonService {Boolean saveCodeToRedis(String mobile, String code);}
最后就可以使用postman等调试工具调试了。
