Spring boot Spring Security OAuth2-从身份验证对象获取自定义主体？

在使用OAuth2时，当我试图从身份验证对象（Authentication.getPrincipal（））访问主体字段时，我当前正在尝试获取一个自定义UserInformation对象。我通过添加.oauth2Login（）属性在WebSecurity ConfigAdapter中启用OAuth2：

@Configuration
public class WebSecurityConfig extends WebSecurityConfigurerAdapter {

    @Override
    protected void configure(HttpSecurity http) throws Exception {
        http
                .authorizeRequests().anyRequest().authenticated()
                .and()
                .oauth2Login();
    }
}

当我添加此属性并尝试从控制器访问主体时，它表示主体的类型是DefaultOidcUser

@RestController
public class OAuthController {

    @GetMapping("/getPrincipal")
    public String authenticate(Authentication authenticate) {
        return "PRINCIPAL CLASS: " + authenticate.getPrincipal().getClass().getName();
    }
}

有没有办法让身份验证主体返回自定义对象（而不是OidcUser）？我试图编写一个自定义OidcService，但它仍然需要返回一个OidcUser

以下是我正在使用的依赖项：

• 弹簧启动启动器安全性：2.2.4-释放
• spring-security-oauth2-client:5.2.1-RELEASE
• spring-security-oauth2-jose:5.2.1-RELEASE

以下是迄今为止我拥有的自定义OidcServer和UserInformation对象：

@Configuration
public class CustomOIDCUserService extends OidcUserService {

    @Override
    public OidcUser loadUser(OidcUserRequest oidcUserRequestst) throws OAuth2AuthenticationException {

        OidcUser oidcUser = super.loadUser(oidcUserRequestst);

        Set<GrantedAuthority> mappedAuthorities = new HashSet<>();
        
        //Add roles to mappedAuthorities

        UserInformation userInfo = new UserInformation(new DefaultOidcUser(mappedAuthorities,
                                                             oidcUser.getIdToken(),
                                                             oidcUser.getUserInfo()));
        //Initialize other fields from oidcUser

        return userInfo;
    }
}

谢谢大家!

public class UserInformation implements OidcUser, UserDetails {

    private OidcUser oidcUser;

    String name;
    String email;

    public UserInformation(OidcUser oidcUser) {
        this.oidcUser = oidcUser;
    }
