“找不到能够从 String 类型转换为 OAuth2ClientProperties$Provider 的转换器” - Spring Boot Oauth 2.0

Question

我的应用程序需要成为一个 API 客户端，在 Spring Boot 中使用 Spring Security、Oauth 2.0 和 OpenID。对于

OAuthClientConfiguration

，我遵循了本教程（从“创建基于 Web 客户端的应用程序”标头开始）：https://developer.okta.com/blog/2021/05/05/client-credentials-spring-security#创建基于 Web 客户端的应用程序

我在启动应用程序时收到此错误：

Failed to bind properties under 'spring.security.oauth2.client.provider.authorization-uri' to org.springframework.boot.autoconfigure.security.oauth2.client.OAuth2ClientProperties$Provider:

    Reason: org.springframework.core.convert.ConverterNotFoundException: No converter found capable of converting from type [java.lang.String] to type [org.springframework.boot.autoconfigure.security.oauth2.client.OAuth2ClientProperties$Provider]

Answer 1

您需要在属性中拥有提供者 ID 密钥：

provider:
  IdOfMyApp:
    authorization-uri: https://api.provider.guys.com/oauth2/auth
    token-uri: https://api.provider.guys.com/oauth2/token
    issuer-uri: https://api.provider.guys.com

Answer 2

我的错误是我们需要在 client-id 及其值和 client-secret 之间添加空格

spring:
  security:
    oauth2:
      client:
        registration:
          github:
            client-id:39a0a1998e0681b3test
            client-secret:1fc36844d9b44baa8cd0test
