session.setAttribute（“ authManager”，manager）拋出NotSerializableException

Question

我正在嘗試使用SocialAuth，並且正在根據此指南進行設置： https : //github.com/3pillarlabs/socialauth/wiki/Getting-Started-with-implementing-SocialAuth

除部分session.setAttribute("authManager", manager);之外， session.setAttribute("authManager", manager);進行得很好session.setAttribute("authManager", manager); 引發NotSerializableException。 根據指南，我必須在會話中存儲SocialAuthManager對象，但是它為我提供了此堆棧跟蹤：

現在我該如何使用呢？ 有人熟悉SocialAuth庫嗎？

Answer 1

您正在嘗試將manager對象存儲在HttpSession 。 請注意，您存儲在會話中的對象必須可序列化。 看起來SocialAuthManager類實際上不是可Serializable ，盡管它聲稱：

• SocialAuthConfig無法序列化

• Log實現對象可能無法序列化

• providersMap的值可能無法序列化
