Description:

Field authenticationManager in com.spud.auth.AuthApplication$OAuth2Config required a bean of type 'org.springframework.security.authentication.AuthenticationManager' that could not be found.


Action:

Consider defining a bean of type 'org.springframework.security.authentication.AuthenticationManager' in your configuration.

【参考方案1】：

您必须将AuthenticationManager 公开为here 描述的spring bean。

我应该提到我查看了其他一些相关的帖子，包括你链接我的帖子。然而，凌晨 4:00 开始了，我想我的阅读技巧出了问题。我取笑你，又读了一遍。这一次，我意识到“当然，将它放在 OAuth2Config 类中是行不通的”。我在正确的类中实现了它并且它有效。这是一个重复的问题。谢谢你，我很抱歉。

没问题。我将问题标记为重复。
