Springboot+Aop用注解实现阿里云短信验证码校验，校验通过自动删除验证码缓存

1.新建操作类型枚举（这里的IEnum是我自定义的http请求拦截接口，不需要的话可以不用实现）

@Getter
@AllArgsConstructor
public enum OperationType implements IEnum<Integer> {/*** 注册*/SIGN_UP(0),/*** 密码登录*/LOGIN_BY_PWD(1),/*** 验证码登录*/LOGIN_BY_SMS(2),/*** 忘记密码*/FORGET_PWD(3),/*** 修改密码*/MODIFY_PWD(4);@JsonValueprivate final int code;@Overridepublic Integer getCode(){return code;}
}

2.新建校验注解

@Target({ElementType.METHOD})
@Retention(RetentionPolicy.RUNTIME)
@Documented
public @interface SmsValidate {/*** 操作类型* @return*/OperationType operationType() default OperationType.LOGIN_BY_PWD;
}

3.创建验证码校验接口

public interface ISmsValidate {/*** 短信验证码手机号* @return*/String mobile();/*** 短信验证码内容* @return*/String smsCode();
}

4.controller方法请求参数，实现ISmsValidate接口

@Data
public class LoginBySmsDto implements ISmsValidate {@NotBlank(message = "用户名/手机号不能为空")@IsMobileprivate String username;@NotBlank(message = "短信验证码不能为空")private String code;@Overridepublic String mobile() {return this.getUsername();}@Overridepublic String smsCode() {return this.getCode();}
}

5.添加aop切面类

@Aspect
@Component
public class SmsValidateAop {@Autowiredprivate RedisTemplate<String,Object> redisTemplate;@Pointcut(value = "@annotation(com.tfyt.common.annotation.SmsValidate)")public void pointCut(){}@Before(value = "pointCut()")public void before(JoinPoint joinPoint){SmsObj smsObj = getSmsObj(joinPoint);Object cacheCode = redisTemplate.opsForValue().get(RedisKeyConstant.CACHE_SMS_CODE + smsObj.getOperationType() + ":" + smsObj.getMobile());BusinessAssert.notTrue(Objects.equals(cacheCode,smsObj.getCode()),"手机验证码不正确");}@AfterReturning(value = "pointCut()")public void after(JoinPoint joinPoint){SmsObj smsObj = getSmsObj(joinPoint);redisTemplate.delete(RedisKeyConstant.CACHE_SMS_CODE + smsObj.getOperationType() + ":" + smsObj.getMobile());}@Data@AllArgsConstructor@NoArgsConstructorprivate static class SmsObj{private String mobile;private String code;private Integer operationType;}private SmsObj getSmsObj(JoinPoint joinPoint){MethodSignature signature = (MethodSignature) joinPoint.getSignature();SmsValidate annotation = signature.getMethod().getAnnotation(SmsValidate.class);BusinessAssert.isNull(annotation,"系统异常：未查询到注解");BusinessAssert.isNull(annotation.operationType(),"系统异常：未配置操作类型");Object[] args = joinPoint.getArgs();ISmsValidate arg = null;if(args[0] instanceof ISmsValidate){arg = (ISmsValidate) args[0];}BusinessAssert.isNull(arg,"请输入用户名和手机验证码");return new SmsObj(arg.mobile(), arg.smsCode(), annotation.operationType().getCode());}
}

6.往controller的方法上注解

@SmsValidate(operationType = OperationType.LOGIN_BY_SMS)

重启springboot项目，调用接口即可生效，校验通过后会自动删除redis缓存

补一个自定义断言类

public class BusinessAssert {public static void notTrue(boolean condition, String msg){isTrue(!condition, msg);}public static void isTrue(boolean condition, String msg){if(condition){throw new BusinessException(HttpStatus.BAD_REQUEST.value(),msg);}}public static void nonNull(Object object,String msg){if(null!=object){throw new BusinessException(HttpStatus.BAD_REQUEST.value(),msg);}}public static void isNull(Object object,String msg){if(null==object){throw new BusinessException(HttpStatus.BAD_REQUEST.value(),msg);}}public static void isCollectionEmpty(Collection<?> collection,String msg){if(collection == null || collection.isEmpty()){throw new BusinessException(HttpStatus.BAD_REQUEST.value(),msg);}}public static void isCollectionNotEmpty(Collection<?> collection,String msg){if(collection != null && !collection.isEmpty()){throw new BusinessException(HttpStatus.BAD_REQUEST.value(),msg);}}
