Spring Security OAuth2 纯资源服务器

Question

我们已经建立了一个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 应该指向令牌处理 bean。然而，令牌处理似乎是由服务器本身完成的，即使它是资源服务器。似乎没有任何远程令牌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？

Answer 1

只要授权服务器和资源服务器访问共享的tokenStore（例如，使用JdbcTokenStore 和公共dataSource），这是可能的。您可以使用 DefaultTokenServices 引用您共享的 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：

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
   xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

    <property name="tokenStore" ref="tokenStore" />
</bean>

<bean id="authenticationEntryPoint" class="org.springframework.security.oauth2.provider.error.OAuth2AuthenticationEntryPoint">
    <property name="realmName" value="myRealm" />

<bean id="oauthAccessDeniedHandler" class="org.springframework.security.oauth2.provider.error.OAuth2AccessDeniedHandler" />

<bean id="accessDecisionManager" class="org.springframework.security.access.vote.UnanimousBased">

            <bean class="org.springframework.security.access.vote.AuthenticatedVoter" />
        </list>
    </constructor-arg>
</bean>

<!-- This is not actually used, but it's required by Spring Security -->

Answer 2

是的，这是可能的。就像您在问题中已经提到的那样，RemoteTokenServices 是解决方案。

我创建了一个具有独立身份验证和资源服务器的示例。它只是一个示例，可让您快速了解该概念并开放扩展。
