You could always store the JSON representation of the object you tried to store.
您始终可以存储您尝试存储的对象的 JSON 表示。
However, I've heard it's generally a good idea not to store large things in the Session, is there anyway you could manage by storing something else? If you are storing an object from the DB, you could store the Id and recover the object with a query.
但是，我听说不要在 Session 中存储大的东西通常是个好主意，无论如何你可以通过存储其他东西来管理？如果您要存储来自数据库的对象，则可以存储 Id 并通过查询恢复该对象。
