You can now leverage Spring Security's <<webclient>> or <<webflux-roac,@RegisteredOAuth2AuthorizedClient>> support to obtain and use the access token.
== BearerTokenResolver
With interface BearerTokenResolver you can provide a strategy to resolve a bearer token.
The interface provides the next method:
[source,java]
----
/**
* Resolve any <a href="https://tools.ietf.org/html/rfc6750#section-1.2" target="_blank">Bearer Token</a>
* value from the request.
*
* @param request the request
* @return the Bearer Token value or {@code null} if none found
* @throws OAuth2AuthenticationException if the found token is invalid
*/
String resolve(HttpServletRequest request);
----
In code base, you can find two implementation of this interface:
HeaderBearerTokenResolver and DefaultBearerTokenResolver (based on RFC 6750).
Below you can see HeaderBearerTokenResolver, it takes a bearer token from request by header
which was passed in constructor
[source,java]
----
public class HeaderBearerTokenResolver implements BearerTokenResolver {
private String header;
public HeaderBearerTokenResolver(String header) {
Assert.hasText(header, "header cannot be empty");
this.header = header;
}
@Override
public String resolve(HttpServletRequest request) {
return request.getHeader(this.header);
}
}

Thus far we have only taken a look at the most basic authentication configuration.
Let's take a look at a few slightly more advanced options for configuring authentication.
[[oauth2resourceserver-bearertoken-resolver]]
=== Bearer Token Resolution
By default, Resource Server looks for a bearer token in the `Authorization` header.
This, however, can be customized in a couple of ways.
==== Reading the Bearer Token from a Custom Header
For example, you may have a need to read the bearer token from a custom header.
To achieve this, you can wire a `HeaderBearerTokenResolver` instance into the DSL, as you can see in the following example:
[source,java]
----
http
.oauth2ResourceServer()
.bearerTokenResolver(new HeaderBearerTokenResolver("x-goog-iap-jwt-assertion"));
----
==== Reading the Bearer Token from a Form Parameter
Or, you may wish to read the token from a form parameter, which you can do by configuring the `DefaultBearerTokenResolver`, as you can see below:
[source,java]
----
DefaultBearerTokenResolver resolver = new DefaultBearerTokenResolver();
resolver.setAllowFormEncodedBodyParameter(true);
http
.oauth2ResourceServer()
.bearerTokenResolver(resolver);
----
=== Bearer Token Propagation
Now that you're in possession of a bearer token, it might be handy to pass that to downstream services.
