在 Java 配置中具有自定义身份验证管理器的 Oauth 授权服务器

Question

我在应用程序中有多个身份验证管理器。我通过 bean 名称来区分它们。我与 oauth 授权服务器相关的部分 xml 配置看起来像，并且工作正常：

<oauth:expression-handler id="oauthExpressionHandler" />
<oauth:web-expression-handler id="oauthWebExpressionHandler" />

<oauth:authorization-server client-details-service-ref="clientDetails" token-services-ref="tokenServices" user-approval-handler-ref="userApprovalHandler" >
    <oauth:authorization-code disabled="true" />
    <oauth:implicit disabled="false" />
    <oauth:refresh-token disabled="false" />
    <oauth:client-credentials disabled="false" />
    <oauth:password authentication-manager-ref="authenticationManager" />
</oauth:authorization-server>

<oauth:resource-server id="resourceServerFilter" resource-id="resource-id" token-services-ref="tokenServices" />

<sec:authentication-manager id="clientAuthenticationManager">
    <sec:authentication-provider user-service-ref="clientDetailsUserService" />
</sec:authentication-manager>

<http pattern="/oauth/token" create-session="stateless" authentication-manager-ref="clientAuthenticationManager"
      xmlns="http://www.springframework.org/schema/security">
    <intercept-url pattern="/oauth/token" access="IS_AUTHENTICATED_FULLY" />
    <anonymous enabled="false" />
    <http-basic entry-point-ref="clientAuthenticationEntryPoint" />
    <!-- include this only if you need to authenticate clients via request parameters -->
    <custom-filter ref="oauthClientCredentialsTokenEndpointFilter" before="BASIC_AUTH_FILTER" />
    <access-denied-handler ref="oauthAccessDeniedHandler" />
</http>

我正在尝试将其移至基于 Java 的配置（在某些 SecurityConfig 类中），到目前为止还没有缺少。我尝试过类似的方法：

@Configuration
@EnableAuthorizationServer
protected static class OAuth2AuthConfig extends AuthorizationServerConfigurerAdapter {

    @Resource(name = "authenticationManager")
    private AuthenticationManager authenticationManager;

    @Resource
    private OAuth2AuthenticationEntryPoint authenticationEntryPoint;

    @Resource(name = "clientDetails")
    private ClientDetailsService clientDetailsService;

    @Resource
    private TokenStore tokenStore;

    @Resource
    private TokenStoreUserApprovalHandler userApprovalHandler;

    @Override
    public void configure(AuthorizationServerSecurityConfigurer security) throws Exception {
        security.authenticationEntryPoint(authenticationEntryPoint);
    }

    @Override
    public void configure(AuthorizationServerEndpointsConfigurer endpoints) throws Exception {
        endpoints.authenticationManager(authenticationManager)
                .userApprovalHandler(userApprovalHandler)
                .tokenStore(tokenStore);
    }

    @Override
    public void configure(ClientDetailsServiceConfigurer clients) throws Exception {
        clients.withClientDetails(clientDetailsService);
    }
}

@Configuration
@EnableResourceServer
protected static class OAuth2ResourceConfig extends ResourceServerConfigurerAdapter {

    @Resource
    private DefaultTokenServices tokenServices;

    @Resource(name = "authenticationManager")
    private AuthenticationManager authenticationManager;

    @Override
    public void configure(ResourceServerSecurityConfigurer resources) {
        resources.resourceId(RESOURCE_ID).tokenServices(tokenServices).authenticationManager(authenticationManager);
    }
}

尽管我明确设置了endpoints.authenticationManager(authenticationManager)，但它仍然抱怨多个身份验证管理器。

通过一些调试，我可以看到它尝试在 WebSecurityConfigurerAdapter 类中对其进行配置，并且它在authenticationManager() 中遇到了多个身份验证管理器。我可以覆盖它还是我错过了什么？

1. AuthorizationServer - 这里有一种方法可以防止 Spring 失败
   org.springframework.security.config.annotation.web.configuration.WebSecurityConfigurerAdapter#authenticationManager 通过简单的覆盖方法 org.springframework.security.oauth2.config.annotation.web.configuration.AuthorizationServerSecurityConfiguration#configure(org.springframework.security.config.annotation.authentication.builders.AuthenticationManagerBuilder) - explanation
2. ResourceServer - 遗憾的是没有办法处理类似的相应问题。您能做的最好的事情是将全局身份验证管理器的实例数量减少到一个。
