接口 UserInfoRestTemplateCustomizer

public interface UserInfoRestTemplateCustomizer

Callback for customizing the rest template used to fetch user details if authentication is done via OAuth2 access tokens. The default should be fine for most providers, but occasionally you might need to add additional interceptors, or change the request authenticator (which is how the token gets attached to outgoing requests). The rest template that is being customized here is only used internally to carry out authentication (in the SSO or Resource Server use cases).
