1.添加依赖

        <dependency>
            <groupId>com.aliyun</groupId>
            <artifactId>dysmsapi20170525</artifactId>
            <version>2.0.24</version>
        </dependency>

2.控制层

@Api(tags = "短信业务接口管理")
@RequestMapping("p/sms")
@RestController
public class SendController {

    @Autowired
    private SendService sendService;


    /**
     * 获取短信验证码
     * @param map 手机号码
     * @return
     */
    @ApiOperation("获取短信验证码")
    @PostMapping("send")
    public Result<String> sendPhoneMsg(@RequestBody Map<String,Object> map) {
        sendService.sendPhoneMsg(map);
        return Result.success("短信发送成功");
    }

    /**
     * 绑定手机号码
     * @param map 手机号码phonenum，短信验证码code
     * @return
     */

//    p/sms/savePhone
    @ApiOperation("绑定手机号码")
    @PostMapping("savePhone")
    public Result<String> saveMsgPhone(@RequestBody Map<String,Object> map) {
        Boolean saved = sendService.saveMsgPhone(map);
        return Result.handle(saved);
    }
}

3.接口

public interface SendService {

    /**
     * 获取短信验证码
     * @param map
     */
    void sendPhoneMsg(Map<String, Object> map);

    /**
     * 绑定手机号码
     * @param map
     * @return
     */
    Boolean saveMsgPhone(Map<String, Object> map);
}

4. 接口实现

@Service
public class SendServiceImpl implements SendService {
    @Autowired
    private AliyunDxConfig aliyunDxConfig;

    @Autowired
    private MemberMapper memberMapper;

    @Autowired
    private StringRedisTemplate stringRedisTemplate;
    @Override
    public void sendPhoneMsg(Map<String, Object> map) {
        // 准备配置对象
        com.aliyun.teaopenapi.models.Config config = new com.aliyun.teaopenapi.models.Config()
                // 必填，请确保代码运行环境设置了环境变量 ALIBABA_CLOUD_ACCESS_KEY_ID。
                .setAccessKeyId(aliyunDxConfig.getAccessKeyID())
                // 必填，请确保代码运行环境设置了环境变量 ALIBABA_CLOUD_ACCESS_KEY_SECRET。
                .setAccessKeySecret(aliyunDxConfig.getAccessKeySecret());
        // Endpoint 请参考 https://api.aliyun.com/product/Dysmsapi
        config.endpoint = aliyunDxConfig.getEndpoint();
        try {
            // 创建客户端对象
            com.aliyun.dysmsapi20170525.Client client = new com.aliyun.dysmsapi20170525.Client(config);
            // 获取手机号码
            String phonenum = (String) map.get("phonenum");
            // 生成一个随机数字
            String randomNumber = RandomUtil.randomNumbers(4);
            // 将生成的随机数字存放到redis中
            stringRedisTemplate.opsForValue().set(MemberConstants.MSG_PHONE_PREFIX+phonenum, randomNumber, Duration.ofMinutes(30));
            // 创建模版参数
            String templateParam = "{\"code\":\""+randomNumber+"\"}";
            // 创建请求参数对象
            com.aliyun.dysmsapi20170525.models.SendSmsRequest sendSmsRequest = new com.aliyun.dysmsapi20170525.models.SendSmsRequest()
                    .setPhoneNumbers(phonenum)
                    .setSignName(aliyunDxConfig.getSignName())
                    .setTemplateCode(aliyunDxConfig.getTemplateCode())
                    .setTemplateParam(templateParam);
            // 发送请求
            client.sendSmsWithOptions(sendSmsRequest, new com.aliyun.teautil.models.RuntimeOptions());
        } catch (Exception e) {
            throw new RuntimeException(e);
        }
    }

    @Override
    public Boolean saveMsgPhone(Map<String, Object> map) {
        // 获取会员输入的短信验证码
        String code = (String) map.get("code");
        // 获取会员手机号码
        String phonenum = (String) map.get("phonenum");
        // 从redis中获取当前手机号码对应验证码
        String redisCode = stringRedisTemplate.opsForValue().get(MemberConstants.MSG_PHONE_PREFIX + phonenum);
        // 判断验证码是否正确
        if (!code.equals(redisCode)) {
            throw new BusinessException("请输入正确的短信验证码");
        }
        // 将会员手机号码更新到会员信息中
        Member member = new Member();
        member.setUserMobile(phonenum);
        // 获取当前会员的openId
        String openId = AuthUtils.getMemberOpenId();
        return memberMapper.update(member,new LambdaUpdateWrapper<Member>()
                .eq(Member::getOpenId,openId)
        )>0;
    }
}

5.配置类

@Data
@AllArgsConstructor
@NoArgsConstructor
@Component
@ConfigurationProperties(prefix = "aliyun.dx")
@RefreshScope
public class AliyunDxConfig {
    /**
     * 阿里云平台访问API接口accessKeyID
     */
    private String accessKeyID;
    /**
     * 阿里云平台访问API接口accessKeySecret
     */
    private String accessKeySecret;
    /**
     * 短信签名
     */
    private String signName;
    /**
     * 短信模版CODE
     */
    private String templateCode;

    /**
     * API访问端点
     */
    private String endpoint;
}
