我在Web应用程序中使用spring-security-oauth2-client。我想使用自定义用户类型。但是在使用身份验证服务器发送的请求正文Insteate OAuthUser时出错。

我使用自定义用户类型的原因是因为我想将hashmap内的字符串值用作nameAttributeKey而不是字符串值。

SecurityConfig

    http.oauth2Login()
      .userInfoEndpoint()
        .customUserType(NaverOAuth2User.class,"naver");

NaverOAuth2User

public class NaverOAuth2User implements OAuth2User {

   public NaverOAuth2User(Collection<? extends GrantedAuthority> authorities,Map<String,Object> attributes,String nameAttributeKey) {
           ...
   }

   ...

}

我希望调用NaverOAuth2User的构造函数，但是在序列化之前导致错误。

我认为构造函数参数错误。
