Spring boot无法找到bean OAuth2AuthorizedClientService

Question

我正在使用webflux和keycloak构建OIDC客户端。我的spring应用无法启动，因为无法在下面找到Bean：

Consider defining a bean of type 'org.springframework.security.oauth2.client.OAuth2AuthorizedClientService' in your configuration.

现在呢...

build.gradle

dependencies {
    compile "org.springframework.boot:spring-boot-starter-webflux:2.0.3.RELEASE"
    compile "org.springframework.security:spring-security-oauth2-client"
    compile "org.springframework.security:spring-security-oauth2-jose"
    compile "org.springframework.boot:spring-boot-devtools"

    compile group: 'org.keycloak', name: 'keycloak-services', version: '4.0.0.Final'
    compile group: 'org.keycloak', name: 'keycloak-admin-client', version: '4.0.0.Final'

    compile "org.projectlombok:lombok"
    compile group: 'org.jboss.resteasy', name: 'resteasy-jackson2-provider', version: '4.0.0.Beta4'

    testCompile('org.springframework.boot:spring-boot-starter-test')
}

application.yml

spring:
  security:
    oauth2:
      client:
        registration:
          google:
            client-id: your-app-client-id
            client-secret: your-app-client-secret
          facebook:
            client-id: your-app-client-id
            client-secret: your-app-client-secret
          keycloak:
            provider: keycloak
            client-id: auth-api
            client-secret: 727bea9d-6e01-433a-960b-83ac5d939adf
            client-name: auth-api
            client-authentication-method: basic
            authorization-grant-type: authorization_code
            redirect-uri-template: '{baseUrl}/login/oauth2/code/{registrationId}'
            scope:
              - openid
              - profile
              - email

        provider:
          keycloak:
            authorization-uri: http://70.314.280.xxx/auth/realms/master/protocol/openid-connect/auth
            token-uri: http://70.314.280.xxx/auth/realms/master/protocol/openid-connect/token
            user-info-uri: http://70.314.280.xxx/auth/realms/master/protocol/openid-connect/userinfo
            jwk-set-uri: http://70.314.280.xxx/auth/realms/master/protocol/openid-connect/certs
            user-name-attribute: preferred_username

显然，它无法创建ClientRegistration对象，但不确定为什么spring不会从yaml文件中选择oauth2设置部分？

感谢您的帮助。

我今天遇到了同样的问题，像往常一样使用Spring + IntelliJ调试源代码非常容易，原因是这行代码：

map.from(properties::getRedirectUri).to(builder::redirectUriTemplate);

代码也可以在这里找到：https://github.com/spring-projects/spring-boot/blob/master/spring-boot-project/spring-boot-autoconfigure/src/main/java/org/springframework/boot/autoconfigure/security/oauth2/client/OAuth2ClientPropertiesRegistrationAdapter.java#L57因此，您不应在Yaml文件中使用redirect-uri-template，而应使用redirect-uri。在学习完教程并粘贴其yaml文件后，我陷入了这个问题。
