Document/Example using JWT Header

Here is a sample of what we have to do to wire up a JWT auth scheme to call our client services. Simply by defining this bean in the admin service project, all outbound calls have the token applied and should pass the remote services JWT auth requirement.

It might be prudent to add this to the security section or examples on how to do this in addition to the basic auth example already provided.

package com.foo.bar;

import de.codecentric.boot.admin.model.Application;
import de.codecentric.boot.admin.web.client.HttpHeadersProvider;
import org.springframework.http.HttpHeaders;
import org.springframework.stereotype.Component;

@Component
public class JwtHeaderProvider implements HttpHeadersProvider {

    @Override
    public HttpHeaders getHeaders(Application application) {
        HttpHeaders headers = new HttpHeaders();
        headers.add("X-Authn-JWT", "[MY TOKEN PROBABLY GENERATED WITH KEY]");
        return headers;
    }
}

This above works because of the @ConditionalOnMissingBean in your AdminServerCoreConfiguration class.

@Bean
@ConditionalOnMissingBean
public HttpHeadersProvider httpHeadersProvider() {
    return new BasicAuthHttpHeaderProvider();
}

Although I think it is trivial too , but for people who are new to Spring Boot and Auto Configuration magic , this could be a useful addition.

Yeah that’s exactly what’s intended. Do you really think it should be in the docs - I don’t. Isn’t this trivial?
