How to use SpringBoot @GroupSequenceProvider annotation to implement bean multi-attribute joint verification-javaTutorial-php.cn

Information

Group sequence @GroupSequenceProvider, @GroupSequence controls the data verification sequence and solves the problem of multi-field joint logic verification

Hibernate Validator provides Non-standard @GroupSequenceProvider annotation. Based on the status of the current object instance, dynamically determine which verification groups to load into the default verification group.
We need to use the DefaultGroupSequenceProvider interface provided by Hibernate Validation to handle the circumstances under which those properties enter the specified group.

1. Preliminary preparation

⏹Note that the custom check value cannot be empty

@Documented
@Target({ ElementType.FIELD })
@Retention(RetentionPolicy.RUNTIME)
@Constraint(validatedBy = {ValidateIntegerNotEmpty.StrictIntegerNotEmptyValidator.class})
@ReportAsSingleViolation
public @interface ValidateIntegerNotEmpty {

    String msgArgs() default "";

	String message() default "{1001E}";

	Class<?>[] groups() default {};

	Class<? extends Payload>[] payload() default {};

	class StrictIntegerNotEmptyValidator implements ConstraintValidator<ValidateIntegerNotEmpty, Integer> {

        @Override
        public boolean isValid(Integer value, ConstraintValidatorContext context) {

            return !ObjectUtils.isEmpty(value);
        }
    }
}

2. Requirements

1 When the review status is 2 (manual initial review rejection), the review rejection reason is Required item, and the range is 1 to 4
When review If the status is other than 2 (under review or passed manual preliminary review), the reason for review rejection is Non-required items
