Imports
java.util.Map, org.springframework.core.MethodParameter, .ReactiveAdapterRegistry, org.springframework.http.HttpHeaders, org.springframework.util.MultiValueMap, org.springframework.web.bind.annotation.RequestHeader, org.springframework.web.reactive.BindingContext, org.springframework.web.reactive.result.method.HandlerMethodArgumentResolverSupport, .SyncHandlerMethodArgumentResolver, org.springframework.web.server.ServerWebExchange
Resolves Map method arguments annotated with @RequestHeader. For individual header values annotated with @RequestHeader see RequestHeaderMethodArgumentResolver instead.

The created Map contains all request header name/value pairs. The method parameter type may be a MultiValueMap to receive all values for a header, not only the first one.
