You have Spring Session on your classpath and no store was provided. We can't take that decision for you as if your classpath changes, the store type may change according to our preferences and you'd lose them without any sort of warning.
您的类路径上有 Spring Session 并且没有提供商店。我们无法为您做出这个决定，就好像您的类路径发生了变化一样，存储类型可能会根据我们的偏好发生变化，并且您会在没有任何警告的情况下丢失它们。
Historically we only supported redis so if you have that we'll use it transparently. Please set spring.session.store-typeto the store you want to use for Spring Session. If Spring Session is on your classpath and you don't want to use it right now, set spring.session.store-type=none
过去我们只支持 redis，所以如果你有，我们会透明地使用它。请设置spring.session.store-type为您要用于 Spring Session 的商店。如果 Spring Session 在您的类路径上并且您现在不想使用它，请设置spring.session.store-type=none
