找不到带有Spring Security 5.3.2 ReactiveClientRegistrationRepository bean的反应性OAuth2

Question

我正在尝试在一个反应型客户端应用程序中实现OAuth2 client_credentials流。我正在使用WebClient。我试过几个在网上找到的例子，到目前为止没有一个对我有效。我在文档和教程中读到的所有内容都说ReactiveClientRegistrationRepository bean是自动配置的，但该bean并没有为我启动。

请帮帮我--我迷路了。

Description:

Parameter 0 of method oauthFilteredWebClient in com.wexotr.tcstranspush.configuration.WebClientConfiguration required a bean of type 'org.springframework.security.oauth2.client.registration.ReactiveClientRegistrationRepository' that could not be found.

Answer 1

如果类路径中存在某些spring-web依赖关系，ReactiveClientRegistrationRepository将不会自动连接。但是如果您定义了自己的ReactiveClientRegistrationRepository bean，您将得到一个“bean已经定义了”错误（因此它最终必须连接，只是不是在配置WebClient bean时）。我不确定哪些spring-web依赖项与spring-webflux依赖项冲突，但尝试消除依赖项，直到自动连接成功。
