springboot-admin監控Oauth2權限管控的服務，401授權問題

只給出關鍵示例，代碼不全，驗證可用

重點是protected void configure(HttpSecurity http)方面裏面的路徑放行

@Configuration
@EnableAuthorizationServer
public class AuthServerConfig extends WebSecurityConfigurerAdapter {

    public AuthServerConfig(TokenEndpoint tokenEndpoint) {
        tokenEndpoint.setOAuth2RequestValidator(new NonScopeOAuth2RequestValidator());
    }

    @Override
    protected void configure(HttpSecurity http) throws Exception {
        http.authorizeRequests()
                .antMatchers("/actuator/**").permitAll()//不對springboot-admin監控的請求進行權限校驗
                .antMatchers("/instances/**").permitAll()//不對springboot-admin監控的實例信息請求進行權限校驗
                .anyRequest().authenticated().and().logout().disable();
    }
