RequestHeaderMapMethodArgumentResolver (Spring Framework 5.2.12.RELEASE API)

java.lang.Object
- org.springframework.web.reactive.result.method.HandlerMethodArgumentResolverSupport
- - org.springframework.web.reactive.result.method.annotation.RequestHeaderMapMethodArgumentResolver

All Implemented Interfaces:
HandlerMethodArgumentResolver, SyncHandlerMethodArgumentResolver
```
public class RequestHeaderMapMethodArgumentResolver
extends HandlerMethodArgumentResolverSupport
implements SyncHandlerMethodArgumentResolver
```
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.
