@RequestHeader and POJO binding

[tsarenkotxt]

Hi, do you have plans to add support for header binding with POJO?

This issue based on stackoverflow question @RequestHeader not binding in POJO but binding only in variable

IMHO, it would be a useful feature, instead of writing custom and similar HandlerMethodArgumentResolver

Some ideas:
add an annotation for method args - @Header
add an annotation for POJO fields - @HeaderParam
add support for validation - @Valid
add support for immutable POJO

Thanks

Based on the SO question, you don't need a custom resolver. Just register a Converter. All method arguments sourced from String-based request values (e.g. @RequestHeader, @CookieValue, @PathVariable, etc) pass through to type conversion from String to the target type.

Support for such annotations on fields is something different.

@rstoyanchev - could you please provide with an example that would be most useful for everyone using Converter
