提示：以下是本篇文章正文内容，下面案例可供参考

一、业务场景

每种业务场景对手机号校验方式可能都不相同

1.1 验证码登录

校验：手机号在系统是否存在，存在则发送短信

1.2 手机号注册

校验：手机号在系统是否已经注册，未注册则发送短信

1.3 忘记密码

校验：手机号在系统是否存在，存在则发送短信

1.4 其他场景…

二. 准备工作

1.注册阿里云账号

2.阿里云申请签名

3.阿里云短信模版

4.阿里云短信控制台测试

三、功能规划

1. 工厂模式根据不同业务进行校验，提高代码的可扩展性

2.不同业务类型使用不同的缓存key

四、业务实现

1.引入jar

		<dependency><groupId>com.aliyun</groupId><artifactId>dysmsapi20170525</artifactId><version>3.1.0</version></dependency>

2.yam配置信息及对应配置类

@Configuration
@ConfigurationProperties(prefix = "aliyun.sms")
@Data
public class AliyunSmsConfig {// 阿里云短信服务accessKeyIdprivate String accessKeyId;// 阿里云短信服务accessKeySecretprivate String accessKeySecret;// 短信签名private String signName;// 短信发送地区private String regionId;// 短信模板private Map<String, String> templates;public String getTemplateCode(String key) {String templateCode = templates.get(key);ArgumentAssert.notBlank(templateCode, "短信模板不存在");return templateCode;}
}

3. 业务工厂: 获取对应业务模版

@Service
@AllArgsConstructor
@Slf4j
public class SmsTemplateFactory {private final LoginSmsTemplate loginSmsTemplate;private final RegisterSmsTemplate registerSmsTemplate;private final ForgotPasswordSmsTemplate forgotPasswordSmsTemplate;/*** 根据场景类型获取对应的模板** @param templateKey 场景类型（login/register/forgotPassword）* @return 对应的模板实现类*/public SmsTemplate getTemplate(String templateKey) {return switch (templateKey) {case "login" -> loginSmsTemplate;case "register" -> registerSmsTemplate;case "forgotPassword" -> forgotPasswordSmsTemplate;default -> throw new IllegalArgumentException("未知的场景类型：" + templateKey);};}
}

4. 发送短信模版：用来发送短信

@Slf4j
public abstract class SmsTemplate {protected abstract void checkBiz(String phoneNumber);/*** 发送短信验证码** @param templateKey 模板key* @param phoneNumber 手机号* @return 是否发送成功*/public boolean sendSms(String templateKey, String phoneNumber) {checkBiz(phoneNumber);SmsCodeCache smsCodeCache = SpringUtils.getBean(SmsCodeCache.class);// 检查发送频率（60秒内只能发送一次）if (!smsCodeCache.checkRateLimit(phoneNumber, 60)) {throw new RuntimeException("发送频率过高，请稍后再试");}String code = this.generateCode(); // 生成验证码boolean isSuccess = this.sendSmsToAliyun(templateKey, phoneNumber, code); // 调用阿里云发送短信if (isSuccess) {// 缓存验证码，有效期5分钟smsCodeCache.cacheCode(templateKey, phoneNumber, code, 5);}return isSuccess;}/*** 调用阿里云短信服务发送短信** @param templateKey 模板key* @param phoneNumber 手机号* @param code        验证码* @return 是否发送成功*/private boolean sendSmsToAliyun(String templateKey, String phoneNumber, String code) {AliyunSmsConfig smsConfig = SpringUtils.getBean(AliyunSmsConfig.class);String templateCode = smsConfig.getTemplateCode(templateKey);try {// 初始化客户端Config config = new Config().setAccessKeyId(smsConfig.getAccessKeyId()).setAccessKeySecret(smsConfig.getAccessKeySecret()).setRegionId(smsConfig.getRegionId());Client client = new Client(config);// 构建请求SendSmsRequest request = new SendSmsRequest().setPhoneNumbers(phoneNumber).setSignName(smsConfig.getSignName()).setTemplateCode(templateCode).setTemplateParam("{\"code\":\"" + code + "\"}");// 发送短信SendSmsResponse response = client.sendSms(request);return "OK".equals(response.getBody().getCode());} catch (Exception e) {log.error("发送短信验证码失败，模版：{}，手机号：{}，验证码：{}，错误：{}", templateKey, phoneNumber, code, e.getMessage());return false;}}/*** 生成6位随机验证码** @return 验证码*/private String generateCode() {Random random = new Random();return String.format("%06d", random.nextInt(1000000));}
}

5. 业务模版：用来校验

5.1 登录

@Component
@AllArgsConstructor
public class LoginSmsTemplate extends SmsTemplate {private final BaseStaffService baseStaffService;@Overridepublic void checkBiz(String phoneNumber) {BaseStaff staff = baseStaffService.getStaffByTelephone(phoneNumber);ArgumentAssert.notNull(staff, "该手机号不存在");}
}

5.2 注册

@Component
@AllArgsConstructor
public class RegisterSmsTemplate extends SmsTemplate {private final BaseStaffService baseStaffService;@Overridepublic void checkBiz(String phoneNumber) {BaseStaff staff = baseStaffService.getStaffByTelephone(phoneNumber);ArgumentAssert.isNull(staff, "该手机号已注册");}
}

5.3 忘记密码

@Component
@AllArgsConstructor
public class ForgotPasswordSmsTemplate extends SmsTemplate {private final BaseStaffService baseStaffService;@Overridepublic void checkBiz(String phoneNumber) {BaseStaff staff = baseStaffService.getStaffByTelephone(phoneNumber);ArgumentAssert.notNull(staff, "该手机号不存在");}
}

6.短信缓存redis

@Component
@AllArgsConstructor
public class SmsCodeCache {private final RedisTemplate<String, String> redisTemplate;// 验证码缓存前缀private static final String CODE_PREFIX = "sms:code:";// 发送频率限制前缀private static final String RATE_LIMIT_PREFIX = "sms:rate:";/*** 缓存验证码** @param templateKey 模板key* @param phoneNumber 手机号* @param code        验证码* @param expireTime  过期时间（分钟）*/public void cacheCode(String templateKey, String phoneNumber, String code, long expireTime) {String key = CODE_PREFIX + templateKey + StrPool.COLON + phoneNumber;redisTemplate.opsForValue().set(key, code, expireTime, TimeUnit.MINUTES);}/*** 获取缓存的验证码** @param templateKey 模板key* @param phoneNumber 手机号* @return 验证码*/public String getCachedCode(String templateKey, String phoneNumber) {String key = CODE_PREFIX + templateKey + StrPool.COLON + phoneNumber;return redisTemplate.opsForValue().get(key);}/*** 删除缓存的验证码** @param templateKey 模板key* @param phoneNumber 手机号*/public void deleteCode(String templateKey, String phoneNumber) {String key = CODE_PREFIX + templateKey + StrPool.COLON + phoneNumber;redisTemplate.delete(key);}/*** 检查发送频率** @param phoneNumber 手机号* @param interval    间隔时间（秒）* @return 是否可以发送*/public boolean checkRateLimit(String phoneNumber, long interval) {String key = RATE_LIMIT_PREFIX + phoneNumber;Long lastSentTime = redisTemplate.opsForValue().getOperations().getExpire(key);if (lastSentTime != null && lastSentTime > 0) {return false; // 还在限制时间内}redisTemplate.opsForValue().set(key, "1", interval, TimeUnit.SECONDS);return true;}
}

7. 请求入口：

@PostMapping("getSmsCode")@ApiOperation(value = "获取短信验证码")public DataResponse<Boolean> getSmsCode(@RequestBody @Validated SmsReqAo ao) {String templateKey = ao.getTemplateKey();return DataResponse.builderSuccess(smsTemplateFactory.getTemplate(templateKey).sendSms(templateKey, ao.getTelephone()));}

8. 参数:SmsReqAo

@Data
@ApiModel("短信求入参")
public class SmsReqAo implements Serializable {private static final long serialVersionUID = 1L;@NotBlank(message = "模版KEY不能为空")@ApiModelProperty(value = "模版KEY", required = true)String templateKey;/*** 手机号*/@ApiModelProperty(value = "手机号", required = true)@NotBlank(message = "手机号不能为为空")@Pattern(regexp = "^1[3-9]\\d{9}$", message = "手机号格式不正确")private String telephone;
}
