Spring Boot + Oauth2 客户端凭据 [英] Spring Boot + Oauth2 client credentials
问题描述
我正在尝试使用 Oath2 和客户端凭据流来保护 Spring Boot 上的微服务.
I am trying to protect my microservices on Spring Boot using Oath2 with Client Credentials flow.
顺便说一下,这些微服务只会通过中间件层相互交谈,我的意思是不需要用户凭据来允许授权(用户登录过程为 Facebook).
By the way, those microservices will only talk each other over the middleware layer, I mean no user credentials are needed to allow the authorization (user login process as Facebook).
我在 Internet 上查找了一些示例,这些示例展示了如何创建授权和资源服务器来管理此通信.但是,我刚刚找到了一些示例,解释了如何使用用户凭据(三条腿)来执行此操作.
I have looked for samples on the Internet showing how to create an authorization and resource server to manage this communication. However I just found examples explaining how to do it using user credentials (three legs).
有没有人有任何示例如何在 Spring Boot 和 Oauth2 中做到这一点?如果可以提供有关所用范围的更多详细信息,令牌交换将不胜感激.
Does anyone have any sample how to do it in Spring Boot and Oauth2? If it is possible give further details about the scopes used, token exchanging would be grateful.
推荐答案
我们使用 Oauth2 客户端凭据方案保护 REST 服务.资源和授权服务在同一个应用中运行,但可以拆分到不同的应用中.
We have REST services protected with Oauth2 Client credentials scheme. The Resource and authorization service are running in the same app, but can be split into different apps.
@Configuration
public class SecurityConfig {
@Configuration
@EnableResourceServer
protected static class ResourceServer extends ResourceServerConfigurerAdapter {
// Identifies this resource server. Usefull if the AuthorisationServer authorises multiple Resource servers
private static final String RESOURCE_ID = "*****";
@Resource(name = "OAuth")
@Autowired
DataSource dataSource;
@Override
public void configure(HttpSecurity http) throws Exception {
// @formatter:off
http
.authorizeRequests().anyRequest().authenticated();
// @formatter:on
}
@Override
public void configure(ResourceServerSecurityConfigurer resources) throws Exception {
resources.resourceId(RESOURCE_ID);
resources.tokenStore(tokenStore());
}
@Bean
public TokenStore tokenStore() {
return new JdbcTokenStore(dataSource);
}
}
@Configuration
@EnableAuthorizationServer
protected static class AuthorizationServerConfiguration extends AuthorizationServerConfigurerAdapter {
@Resource(name = "OAuth")
@Autowired
DataSource dataSource;
@Bean
public TokenStore tokenStore() {
return new JdbcTokenStore(dataSource);
}
@Override
public void configure(AuthorizationServerEndpointsConfigurer endpoints) throws Exception {
endpoints.tokenStore(tokenStore());
}
@Override
public void configure(ClientDetailsServiceConfigurer clients) throws Exception {
clients.jdbc(dataSource);
}
}
}
Oauth2 表的数据源配置:
Datasource config for the Oauth2 tables:
@Bean(name = "OAuth")
@ConfigurationProperties(prefix="datasource.oauth")
public DataSource secondaryDataSource() {
return DataSourceBuilder.create().build();
}
与身份验证通信资源服务器如下
Communicating with authentication & resource server goes as followed
curl -H "Accept: application/json" user:password@localhost:8080/oauth/token -d grant_type=client_credentials
curl -H "Authorization: Bearer token" localhost:8080/...
Oauth2 数据库中存在以下记录:
The following record is present in the Oauth2 Database:
client_id resource_ids client_secret scope authorized_grant_types web_server_redirect_uri authorities access_token_validity refresh_token_validity additional_information autoapprove
user **** password NULL client_credentials NULL X NULL NULL NULL NULL
客户端应用中的 Resttemplate 配置
Resttemplate configuration in client application
@Configuration
@EnableOAuth2Client
public class OAuthConfig {
@Value("${OAuth2ClientId}")
private String oAuth2ClientId;
@Value("${OAuth2ClientSecret}")
private String oAuth2ClientSecret;
@Value("${Oauth2AccesTokenUri}")
private String accessTokenUri;
@Bean
public RestTemplate oAuthRestTemplate() {
ClientCredentialsResourceDetails resourceDetails = new ClientCredentialsResourceDetails();
resourceDetails.setId("1");
resourceDetails.setClientId(oAuth2ClientId);
resourceDetails.setClientSecret(oAuth2ClientSecret);
resourceDetails.setAccessTokenUri(accessTokenUri);
/*
When using @EnableOAuth2Client spring creates a OAuth2ClientContext for us:
"The OAuth2ClientContext is placed (for you) in session scope to keep the state for different users separate.
Without that you would have to manage the equivalent data structure yourself on the server,
mapping incoming requests to users, and associating each user with a separate instance of the OAuth2ClientContext."
(http://projects.spring.io/spring-security-oauth/docs/oauth2.html#client-configuration)
Internally the SessionScope works with a threadlocal to store variables, hence a new thread cannot access those.
Therefore we can not use @Async
Solution: create a new OAuth2ClientContext that has no scope.
*Note: this is only safe when using client_credentials as OAuth grant type!
*/
// OAuth2RestTemplate restTemplate = new OAuth2RestTemplate(resourceDetails, oauth2ClientContext);
OAuth2RestTemplate restTemplate = new OAuth2RestTemplate(resourceDetails, new DefaultOAuth2ClientContext());
return restTemplate;
}
}
您可以注入 restTemplate 以(异步)与 Oauth2 安全服务对话.我们目前不使用范围.
You can inject the restTemplate to talk (Asynchronously) to the Oauth2 secured service. We do not use scope at the moment.
