@QueryMap doesn't work with inheritance

[StasKolodyuk]

Hi,

I've raised an issue in spring-cloud-openfeign project related to @SpringQueryMap not working with inheritance.

However, seems like the root cause is in FieldQueryMapEncoder of feign-core

feign/core/src/main/java/feign/querymap/FieldQueryMapEncoder.java

Lines 69 to 75 in 10a4ead

	private static ObjectParamMetadata parseObjectType(Class<?> type) {
	return new ObjectParamMetadata(
	Arrays.stream(type.getDeclaredFields())
	.filter(field -> !field.isSynthetic())
	.peek(field -> field.setAccessible(true))
	.collect(Collectors.toList()));
	}

It uses type.getDeclaredFields() which returns only fields of a class without inherited fields.

Thanks

Thanks for bringing this up. If I recall, this is by design, as Feign's support for bean properties is intentionally simple. This would be an enhancement for us. So I've marked this issue as such. If you would like this feature, please feel free to open a PR.

谢谢你提出这个问题。如果我记得，这是设计，因为Feign对bean属性的支持是故意简单的。这对我们来说是一种增强。所以我已经标记了这个问题。如果您想要此功能，请随时打开公关。

support inheritance is very important
