我一直在尝试按照发现的教程进行操作 HERE用于设置演示以帮助我在另一个项目中实现之前了解本地计算机上的 SSO。我遇到了一个让我陷入困境的问题。我收到错误提示我添加一个 bean。请让我知道我缺少什么代码。我无法让程序运行。

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.

最佳答案

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

关于java - Spring 需要一个类型为 'AuthenticationManager' 的 bean，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/49473634/
