@setu给了你解决问题的必备信息。

请考虑以下代码，这些代码改编自您引用的一篇文章中的代码：

@SpringBootApplication
@EnableWebSecurity
@EnableGlobalMethodSecurity(prePostEnabled = true)
public class X509AuthenticationServer extends WebSecurityConfigurerAdapter {
  ...

  @Override
  protected void configure(HttpSecurity http) throws Exception {
    http
      .authorizeRequests()
        // Define the mapping between the different endpoints
        // and the corresponding user roles
        .antMatchers("/actuator/health").hasRole("ACTUATOR_HEALTH")
        .antMatchers("/actuator/prometheus").hasRole("ACTUATOR_PROMETEUS")
        .antMatchers("/config/myservice").hasRole("CONFIG_MYSERVICE")
        // Please, adjust the fallback as appropriate
        .anyRequest().authenticated()
      .and()
        // Configure X509Configurer (https://docs.spring.io/spring-security/site/docs/current/api/org/springframework/security/config/annotation/web/configurers/X509Configurer.html)
        .x509()
          .subjectPrincipalRegex("CN=(.*?)(?:,|$)")
          .userDetailsService(userDetailsService())
    ;
  }

  @Bean
  public UserDetailsService userDetailsService() {
    // Ideally this information will be obtained from a database or some
    // configuration information
    return new UserDetailsService() {

      @Override
      public UserDetails loadUserByUsername(String username) {

        Objects.requireNonNull(username);

        List<GrantedAuthority> authorities = null;
        switch (username) {
          // Match the different X509 certificate CNs. Maybe you can use the
          // X509 certificate subject distinguished name to include the role in
          // some way and obtain it directly with the subjectPrincipalRegex
          case "Alice":
            authorities = AuthorityUtils
              .commaSeparatedStringToAuthorityList("ROLE_ACTUATOR_HEALTH, ROLE_CONFIG_MYSERVICE");
            break;

          case "Bob":
            authorities = AuthorityUtils
              .commaSeparatedStringToAuthorityList("ROLE_ACTUATOR_PROMETHEUS");
            break;

          default:
            throw new UsernameNotFoundException(String.format("User '%s' not found!", username));
        }

        return new User(username, "", authorities);
      }
    };
  }
}

请根据需要修改代码，以满足实际的endpoint和用户。
