使用Spring Security5 OAuth，我成功地完成了整个身份验证/授权周期，使用Google作为OAuth提供程序，但如果我使用自己制作的在不同应用程序上运行的OAuth提供程序，则会遇到困难。

我使用以下两个依赖项：

<dependency>
            <groupId>org.springframework.security</groupId>
            <artifactId>spring-security-oauth2-client</artifactId>
        </dependency>
        <dependency>
            <groupId>org.springframework.security</groupId>
            <artifactId>spring-security-oauth2-jose</artifactId>
        </dependency>

在使用谷歌时，我只是配置了以下内容：

spring.security.oauth2.client.registration.google.client-id=xxx
spring.security.oauth2.client.registration.google.client-secret=xxx

当使用谷歌(或Facebook、Github或Okta)时，会有一个默认配置来处理其他设置。

现在，我创建了自己的OAuth提供程序。这也是一个Spring Boot应用程序，配置了@EnableAuthorizationServer和其他相当标准的应用程序，尽管它有定制的主体。这也运行在本地主机上，但端口为8081。资源服务器中的配置如下：

spring.security.oauth2.client.registration.bx.client-id=xxx
spring.security.oauth2.client.registration.bx.client-secret=xxx
spring.security.oauth2.client.registration.bx.client-name=bx
spring.security.oauth2.client.registration.bx.provider=bx
spring.security.oauth2.client.registration.bx.scope=user
spring.security.oauth2.client.registration.bx.redirect-uri-template=http://localhost:8080/login/oauth2/code/bx
spring.security.oauth2.client.registration.bx.client-authentication-method=basic
spring.security.oauth2.client.registration.bx.authorization-grant-type=authorization_code

spring.security.oauth2.client.provider.bx.authorization-uri=http://localhost:8081/oauth/authorize
spring.security.oauth2.client.provider.bx.token-uri=http://localhost:8081/oauth/token
spring.security.oauth2.client.provider.bx.user-info-uri=http://localhost:8081/oauth/userInfo
spring.security.oauth2.client.provider.bx.user-name-attribute=name

当尝试使用它登录时，我被正确地重定向到OAuth提供程序，在那里我可以登录并允许使用默认生成的接口访问请求的作用域：

点击授权后，我被困在回调部分。我可以看到回调到
http://localhost:8080/login/oauth2/code/bx?code=xxx&state=xxx

从OAuth服务器返回，这将导致在Spring中显示一个默认的HTML页面，其中包含以下信息：

您的登录尝试不成功，请重试。

原因：[AUTHORIZATION_REQUEST_NOT_FOUND]

使用OAuth 2.0登录

资源服务器中的日志很长，但我提取了有用的部分：

..。和其他一些看起来不相关的堆栈跟踪

查看抛出异常的位置的源代码时，从https://github.com/spring-projects/spring-security/blob/master/oauth2/oauth2-client/src/main/java/org/springframework/security/oauth2/client/web/OAuth2LoginAuthenticationFilter.java开始，它显示了从第145行开始的以下代码：

OAuth2AuthorizationRequest authorizationRequest = this.authorizationRequestRepository.removeAuthorizationRequest(request);
        if (authorizationRequest == null) {
            OAuth2Error oauth2Error = new OAuth2Error(AUTHORIZATION_REQUEST_NOT_FOUND_ERROR_CODE);
            throw new OAuth2AuthenticationException(oauth2Error, oauth2Error.toString());
}

这条信息的确切含义是什么？我怎么会到这个地步？

或者我是否应该自己为回调URL添加一个处理程序，并编写定制代码来获取实际的访问令牌？图书馆肯定应该处理这件事吧？为什么作为OAuth提供商的谷歌会自动处理此案？

我很乐意提供任何代码/进一步的配置。
