**tl;dr：**为什么我的OidcUserService没有注册？

我正尝试使用我自己的OAuth2UserService，方法是按照Spring Security文档中的说明注册它。
然而，当我在OidcUserService.loadUser(OidcUserRequest)]（https：//docs.spring.io/spring-security/site/docs/current/api/org/springframework/security/oauth2/client/oidc/userinfo/oidcUserService.html#loadUser-org.springframework.security.oauth2.client.oidc.userinfo.oidcUserRequest-）方法上设置断点时，它却一直命中com.okta.spring.boot.oauth.OktaOidcUserService！我 * 正在 * 使用com.okta.spring:okta-spring-boot-parent:1.2.2-SNAPSHOT，这可能是问题所在？
我注册了我的OidcUserService，如文档所示：

@SpringBootApplication
@EnableGlobalMethodSecurity(prePostEnabled = true, securedEnabled = true)
public class RedirectCodeFlowApplication {

    public static void main(String[] args) {
        SpringApplication.run(RedirectCodeFlowApplication.class, args);
    }

    @Configuration
    static class WebConfig extends WebSecurityConfigurerAdapter {
        @Override
        protected void configure(HttpSecurity http) throws Exception {
            final OidcUserService delegate = new OidcUserService();

            http.authorizeRequests().anyRequest().authenticated()
                .and()
                .oauth2Login()
                .userInfoEndpoint()
                .oidcUserService( (userRequest) -> {
                        System.out.println( "!!xXx!! never gets here" );

                        OidcUser oidcUser = delegate.loadUser(userRequest);

                        OAuth2AccessToken accessToken = userRequest.getAccessToken();
                        Set<GrantedAuthority> mappedAuthorities = new HashSet<>();

                        oidcUser = new DefaultOidcUser(mappedAuthorities, oidcUser.getIdToken(), oidcUser.getUserInfo());

                        return oidcUser;
                    })
            ;
        }

我调用的方法很简单：

@RestController
public class WelcomeController {

    @GetMapping("/")
    public Welcome getMessageOfTheDay(Principal principal) {
        return "The message of the day is boring.";
    }
}
