首先创建一个UserAuthenticationConverter:

First create a UserAuthenticationConverter:

public class OidcUserAuthenticationConverter implements UserAuthenticationConverter {

    final String SUB = "sub";

    @Override
    public Map<String, ?> convertUserAuthentication(Authentication userAuthentication) {
        throw new UnsupportedOperationException();
    }

    @Override
    public Authentication extractAuthentication(Map<String, ?> map) {
        if (map.containsKey(SUB)) {
            Object principal = map.get(SUB);
            Collection<? extends GrantedAuthority> authorities = null;
            return new UsernamePasswordAuthenticationToken(principal, "N/A", authorities);
        }
        return null;
    }
}

然后像这样配置 spring 来使用它:

Then configure spring to use it like so:

@Configuration
public class OidcJwkTokenStoreConfiguration {
    private final ResourceServerProperties resource;

    public OidcJwkTokenStoreConfiguration(ResourceServerProperties resource) {
        this.resource = resource;
    }

    @Bean
    public TokenStore jwkTokenStore() {
        DefaultAccessTokenConverter tokenConverter = new DefaultAccessTokenConverter();
        tokenConverter.setUserTokenConverter(new OidcUserAuthenticationConverter());
        return new JwkTokenStore(this.resource.getJwk().getKeySetUri(), tokenConverter);
    }
}
