SpringSecurityプラグインを使用するgrailsアプリケーションを作成しています。春のセキュリティプラグインの次の属性をオンにしました
grails.plugins.springsecurity.useSessionFixationPrevention = true grails.plugins.springsecurity.SessionFixationPrevention.migrate = true grails.plugins.springsecurity.SessionFixationPrevention.alwaysCreateSession = true
AuthenticationProviderに次のコードがあります
def session = RequestContextHolder.currentRequestAttributes（）。getSession（）
session.key="いくつかの値"
これで、認証後、RememberMeServiceクラスのloginSuccessメソッドのコードが呼び出され、配置されたセッションで値を取得しようとすると、このエラーが発生します。
j
ava.lang.IllegalStateException：getAttribute：セッションはすでにorg.apache.catalina.session.StandardSession.getAttribute（StandardSession.java:1014）のorg.apache.catalina.session.StandardSessionFacade.getAttribute（StandardSessionFacade.java:110）で無効になっています。

私の質問は、なぜこれが発生するのか、RememberMeServiceでアクセスできるAuthenticationProviderにデータを設定するにはどうすればよいですか？
ありがとう
