Hibernate自定义验证器，如何设置propertyPath？

Question

我们实现了一个自定义的Validator。

我们得到的消息是好的，但不是propertyPath，我们怎么能把它拉回来呢？

我们对象中的实现

@RequiredIfSet.List({
        @RequiredIfSet(propertyPath = "reporterFirstName", field = "isFillingOutForSomeoneElse", dependentField = "reporterFirstName", message = "Reporter First may not be null"),
        @RequiredIfSet(propertyPath = "reporterLastName", field = "isFillingOutForSomeoneElse", dependentField = "reporterLastName", message = "Reporter Last may not be null"),
        @RequiredIfSet(propertyPath = "reporterContactPhone", field = "isFillingOutForSomeoneElse", dependentField = "reporterContactPhone", message = "Reporter Contact Phone may not be null"),
        @RequiredIfSet(propertyPath = "reporterEmail", field = "isFillingOutForSomeoneElse", dependentField = "reporterEmail", message = "Reporter Email may not be null")
})

//约束类

@Documented
@Retention(RetentionPolicy.RUNTIME)
@Target({ElementType.TYPE, ElementType.ANNOTATION_TYPE})
@Constraint(validatedBy = RequiredIfSetValidator.class)
public @interface RequiredIfSet {
    String field();
    String dependentField();

    Class<?>[] groups() default {};
    Class<? extends Payload>[] payload() default {};
    String message() default "Field Required";
    String propertyPath() default "";

    @Target({ElementType.TYPE, ElementType.ANNOTATION_TYPE})
    @Retention(RetentionPolicy.RUNTIME)
    @Documented
    @interface List {
        RequiredIfSet[] value();
    }
}

//我们遍历无效字段的位置

List<String[]> invalidFields = new ArrayList<String[]>();
        Iterator<ConstraintViolation<T>> iterator = cv.iterator();
        while(iterator.hasNext()) {
            ConstraintViolation<T> i = iterator.next();
            String property = i.getPropertyPath().toString();
            String message = i.getMessage();
            invalidFields.add(new String[] { property, message });
        }
        EntityValidationDTO EVDTO = new EntityValidationDTO();
        EVDTO.setStatus("fail");
        EVDTO.setInvalidFields(invalidFields);
        return EVDTO;

在你的"RequiredIfSetValidator“中，在isValid方法中添加如下内容：

if( !valid ) {
        context.buildConstraintViolationWithTemplate(context.getDefaultConstraintMessageTemplate()).addNode("fieldName").addConstraintViolation();
}
