Spring需要一个’AuthenticationManager’类型的bean
我一直在尝试按照在这里找到的教程来设置演示，以帮助我在我的本地机器上理解SSO，然后再在另一个项目中实现。 我遇到了一个让我陷入困境的问题。 我收到并告诉我添加一个bean的错误。 请告诉我我错过的代码。 我无法让程序运行。

错误给定 （运行时没有完整的控制台输出，但这是错误）
*************************** APPLICATION FAILED TO START *************************** 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.
您必须将AuthenticationManager公开为此处描述的spring bean。
