Yes, i have configured wp pauth server with enabled:
Authorization code and refresh code.
After that I’ve configured my spring ouath 2 as follow:

wp:
  client:
    clientId: xxx
    clientSecret: xxx
    accessTokenUri: http://localhost:8080/wordpress?oauth=access_token
    userAuthorizationUri: http://localhost:8080/wordpress?oauth=authorize
  resource:
    userInfoUri: http://localhost:8080/wordpress/oauth/me

and this is my java config:

@EnableOAuth2Client
@Configuration
public class SpringSecurityConfig  extends WebSecurityConfigurerAdapter {

    @Autowired
    OAuth2ClientContext oauth2ClientContext;

    @RequestMapping("/user")
    public Principal user(Principal principal) {
        return principal;
    }

    @Override
    protected void configure(HttpSecurity http) throws Exception {
        // @formatter:off
        http.antMatcher("/**")
                .authorizeRequests()
                .antMatchers("/", "/login**", "/webjars/**").permitAll()
                .anyRequest().authenticated()
                .and().exceptionHandling().authenticationEntryPoint(new LoginUrlAuthenticationEntryPoint("/"))
                .and().logout().logoutSuccessUrl("/").permitAll()
                .and().csrf().csrfTokenRepository(csrfTokenRepository())
                .and().addFilterAfter(csrfHeaderFilter(), CsrfFilter.class)
                .addFilterBefore(ssoFilter(), BasicAuthenticationFilter.class);
        // @formatter:on
    }

    @Bean
    public FilterRegistrationBean oauth2ClientFilterRegistration(
            OAuth2ClientContextFilter filter) {
        FilterRegistrationBean registration = new FilterRegistrationBean();
        registration.setFilter(filter);
        registration.setOrder(-100);
        return registration;
    }

    private Filter ssoFilter() {
        OAuth2ClientAuthenticationProcessingFilter wpFilter = new OAuth2ClientAuthenticationProcessingFilter("/login/wp");
        OAuth2RestTemplate wpTemplate = new OAuth2RestTemplate(wp(), oauth2ClientContext);
        wpFilter.setRestTemplate(wpTemplate);
        wpFilter.setTokenServices(new UserInfoTokenServices(wpResource().getUserInfoUri(), wp().getClientId()));
        return wpFilter;
    }

    @Bean
    @ConfigurationProperties("wp.client")
    OAuth2ProtectedResourceDetails wp() {
        return new AuthorizationCodeResourceDetails();
    }

    @Bean
    @ConfigurationProperties("wp.resource")
    ResourceServerProperties wpResource() {
        return new ResourceServerProperties();
    }

    private Filter csrfHeaderFilter() {
        return new OncePerRequestFilter() {
            @Override
            protected void doFilterInternal(HttpServletRequest request, HttpServletResponse response,
                                            FilterChain filterChain) throws ServletException, IOException {
                CsrfToken csrf = (CsrfToken) request.getAttribute(CsrfToken.class.getName());
                if (csrf != null) {
                    Cookie cookie = WebUtils.getCookie(request, "XSRF-TOKEN");
                    String token = csrf.getToken();
                    if (cookie == null || token != null && !token.equals(cookie.getValue())) {
                        cookie = new Cookie("XSRF-TOKEN", token);
                        cookie.setPath("/");
                        response.addCookie(cookie);
                    }
                }
                filterChain.doFilter(request, response);
            }
        };
    }

    private CsrfTokenRepository csrfTokenRepository() {
        HttpSessionCsrfTokenRepository repository = new HttpSessionCsrfTokenRepository();
        repository.setHeaderName("X-XSRF-TOKEN");
        return repository;
    }

shuld be ok but every time i try to log I’ve got this message:
There was an unexpected error (type=Unauthorized, status=401).
Authentication Failed: Could not obtain access token
