Spring Boot无法找到OAuth2AuthorizedClientService bean。

Question

我正在使用webflux和keycloak构建OIDC客户端。由于无法找到以下bean，我的spring应用程序无法启动：

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

现在开始... 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无法从yaml文件中选择oauth2设置部分？

谢谢你的帮助。

“- email”和“provider:”之间的空格可能会成为一个问题。 - LMC

@LuisMuñoz 谢谢，但那不是问题。 - Chirdeep Tomar

@ChirdeepTomar：我也遇到了同样的问题。你是如何解决的？ - Vijay

今天我遇到了同样的问题，使用Spring + IntelliJ进行源代码调试非常容易，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，在您的yaml文件中，不应该使用redirect-uri-template而是redirect-uri。
我在跟随教程并复制他们的yaml文件时遇到了这个问题。
