我们已经实现了一个自定义验证器。
我们得到消息返回 OK，但不是 propertyPath，我们怎样才能把它拉回来？
在我们的对象中实现
@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

//我们遍历无效字段的地方
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;
