我们已经搭建了一个OAuth2授权服务器，所以我需要创建一个对应的资源服务器(单独的服务器)。我们计划使用 Spring Security OAuth2 项目。他们设置资源服务器的文档:

https://github.com/spring-projects/spring-security-oauth/wiki/oAuth2#resource-server-configuration

token-services-ref 应该指向 token 处理 bean。然而， token 处理似乎是由服务器本身完成的，即使它是资源服务器。似乎没有任何远程 token 服务类或与远程服务器相关的任何配置。这与 CloudFoundary UAA (https://github.com/cloudfoundry/uaa/blob/master/samples/api/src/main/webapp/WEB-INF/spring-servlet.xml) 形成对比，后者具有:

<bean id="tokenServices"
  class="org.cloudfoundry.identity.uaa.oauth.RemoteTokenServices">
  <property name="checkTokenEndpointUrl" value="${checkTokenEndpointUrl}" />

有没有办法将 Spring Security OAuth2 用于与单独的 OAuth2 授权服务器通信的资源服务器？如何设置通信端点？

最佳答案

只要授权服务器和资源服务器访问共享的 tokenStore(例如，将 JdbcTokenStore 与公共(public)的 dataSource 一起使用)，这是可能的>)。您可以使用 DefaultTokenServices 来引用您的共享 tokenStore。下面是一个示例 Spring 配置，您应该可以对其进行调整以满足您的需求:
