二、代码实现
2-1.注解定义
/*** author ZhangLiFang* date 2022/7/1 10:01 PM* Desc*/
Retention(RetentionPolicy.RUNTIME)
Target(ElementType.METHOD)
public interface ValidGroupParam {Class?[] value() default Default.class;
}2-2.组定义
/*** author ZhangLiFang* date 2022/7/1 11:41 PM* Desc ValidGroupParam校验的参数组*/
public interface InboundOrderGroup {/*** 加款*/interface Inbound extends Default {}/*** 调额*/interface AdjustInCome extends Default {}}2-3.constraints使用
/*** author ZhangLiFang* date 2022/7/1 5:24 PM* Desc*/Builder
AllArgsConstructor
NoArgsConstructor
Data
public class InboundMidRequest implements Serializable {private static final long serialVersionUID 8666517965899046452L;/*** 金额 默认组校验*/NotNull(message 金额不能为空)private BigDecimal amount;/*** 币种 对于加款组需要做校验*/NotBlank(groups InboundOrderGroup.Inbound.class, message币种不能为空)private String currency;/*** 平台 对于调额组需要做校验*/NotBlank(groups InboundOrderGroup.AdjustInCome.class, message平台不能为空)private String platform;
}2-4.切面定义
/*** author ZhangLiFang* date 2022/7/1 10:13 PM* Desc*/
Aspect
Component
public class ValidGroupParamAspect {Resourceprivate ValidatorFactory factory;Pointcut(annotation(validGroupParam))public void callAt(ValidGroupParam validGroupParam) {}Around(value callAt(validGroupParam), argNames pjp,validGroupParam)public Object around(Valid ProceedingJoinPoint pjp, ValidGroupParam validGroupParam) throws Throwable {Validator validator factory.getValidator();for (Object o : pjp.getArgs()) {SetConstraintViolationObject violations validator.validate(o, validGroupParam.value());for (ConstraintViolationObject violation : violations) {String errorMsg violation.getMessage();throw new BizException(ErrorCode.PARAM_ERROR, errorMsg);}}return pjp.proceed();}}2-5.复用ValidatorFactory
/*** author ZhangLiFang* date 2022/7/4 5:22 PM* Desc*/
Component
public class ValidatorTemplateFactory {Beanpublic ValidatorFactory validatorFactory(){return Validation.buildDefaultValidatorFactory();}}2-6.单测校验
针对加款组调用接口
Slf4j
Service
public class AnnotationTestService {ValidGroupParam(InboundOrderGroup.Inbound.class)public void testAnnotation(InboundMidRequest inboundMidRequest){log.info(okkkk);}
}单测1缺少默认组参数执行结果金额不能为空 Testpublic void test_Annotation_ValidGroupParam_without_default_arg(){InboundMidRequest build InboundMidRequest.builder().amount(null).currency(CNY).platform(平台).build();annotationTestService.testAnnotation(build);}单测2缺少调额组的参数执行结果okkkk
Test
public void test_Annotation_ValidGroupParam_without_other_group_arg(){InboundMidRequest build InboundMidRequest.builder().amount(new BigDecimal(100)).currency(CNY).platform().build();annotationTestService.testAnnotation(build);
}单测3缺少加款组的参数执行结果币种不能为空
Testpublic void test_Annotation_ValidGroupParam_without_own_group_arg(){InboundMidRequest build InboundMidRequest.builder().amount(new BigDecimal(100)).currency().platform(平台).build();annotationTestService.testAnnotation(build);}单测结果表明分组成功ValidGroupParam(InboundOrderGroup.Inbound.class)即可实现分组校验。
2-7.说明
ValidGroupParam注解支持可多个组参数校验同时也支持对方法的多个Object参数的constraints进行校验。即
ValidGroupParam({InboundOrderGroup.Inbound.class, InboundOrderGroup.Inbound2.class})
public void testAnnotation(InboundMidRequest1 inboundMidRequest1, InboundMidRequest2 inboundMidRequest2){log.info(okkkk,too);
}注意以最先匹配到不符合的参数条件的一条message进行抛出异常告警。
