OAuth 2.0 Client
The OAuth 2.0 Client features provide support for the Client role as defined in the OAuth 2.0 Authorization Framework.
At a high-level, the core features available are:
-
WebClient
integration for Servlet Environments (for requesting protected resources)
The HttpSecurity.oauth2Client()
DSL provides a number of configuration options for customizing the core components used by OAuth 2.0 Client.
In addition, HttpSecurity.oauth2Client().authorizationCodeGrant()
enables the customization of the Authorization Code grant.
The following code shows the complete configuration options provided by the HttpSecurity.oauth2Client()
DSL:
-
Java
-
Kotlin
@Configuration
@EnableWebSecurity
public class OAuth2ClientSecurityConfig {
@Bean
public SecurityFilterChain filterChain(HttpSecurity http) throws Exception {
http
.oauth2Client(oauth2 -> oauth2
.clientRegistrationRepository(this.clientRegistrationRepository())
.authorizedClientRepository(this.authorizedClientRepository())
.authorizedClientService(this.authorizedClientService())
.authorizationCodeGrant(codeGrant -> codeGrant
.authorizationRequestRepository(this.authorizationRequestRepository())
.authorizationRequestResolver(this.authorizationRequestResolver())
.accessTokenResponseClient(this.accessTokenResponseClient())
)
);
return http.build();
}
}
@Configuration
@EnableWebSecurity
class OAuth2ClientSecurityConfig {
@Bean
open fun filterChain(http: HttpSecurity): SecurityFilterChain {
http {
oauth2Client {
clientRegistrationRepository = clientRegistrationRepository()
authorizedClientRepository = authorizedClientRepository()
authorizedClientService = authorizedClientService()
authorizationCodeGrant {
authorizationRequestRepository = authorizationRequestRepository()
authorizationRequestResolver = authorizationRequestResolver()
accessTokenResponseClient = accessTokenResponseClient()
}
}
}
return http.build()
}
}
In addition to the HttpSecurity.oauth2Client()
DSL, XML configuration is also supported.
The following code shows the complete configuration options available in the security namespace:
<http>
<oauth2-client client-registration-repository-ref="clientRegistrationRepository"
authorized-client-repository-ref="authorizedClientRepository"
authorized-client-service-ref="authorizedClientService">
<authorization-code-grant
authorization-request-repository-ref="authorizationRequestRepository"
authorization-request-resolver-ref="authorizationRequestResolver"
access-token-response-client-ref="accessTokenResponseClient"/>
</oauth2-client>
</http>
The OAuth2AuthorizedClientManager
is responsible for managing the authorization (or re-authorization) of an OAuth 2.0 Client, in collaboration with one or more OAuth2AuthorizedClientProvider
(s).
The following code shows an example of how to register an OAuth2AuthorizedClientManager
@Bean
and associate it with an OAuth2AuthorizedClientProvider
composite that provides support for the authorization_code
, refresh_token
, client_credentials
, and password
authorization grant types:
-
Java
-
Kotlin
@Bean
public OAuth2AuthorizedClientManager authorizedClientManager(
ClientRegistrationRepository clientRegistrationRepository,
OAuth2AuthorizedClientRepository authorizedClientRepository) {
OAuth2AuthorizedClientProvider authorizedClientProvider =
OAuth2AuthorizedClientProviderBuilder.builder()
.authorizationCode()
.refreshToken()
.clientCredentials()
.password()
.build();
DefaultOAuth2AuthorizedClientManager authorizedClientManager =
new DefaultOAuth2AuthorizedClientManager(
clientRegistrationRepository, authorizedClientRepository);
authorizedClientManager.setAuthorizedClientProvider(authorizedClientProvider);
return authorizedClientManager;
}
@Bean
fun authorizedClientManager(
clientRegistrationRepository: ClientRegistrationRepository,
authorizedClientRepository: OAuth2AuthorizedClientRepository): OAuth2AuthorizedClientManager {
val authorizedClientProvider: OAuth2AuthorizedClientProvider = OAuth2AuthorizedClientProviderBuilder.builder()
.authorizationCode()
.refreshToken()
.clientCredentials()
.password()
.build()
val authorizedClientManager = DefaultOAuth2AuthorizedClientManager(
clientRegistrationRepository, authorizedClientRepository)
authorizedClientManager.setAuthorizedClientProvider(authorizedClientProvider)
return authorizedClientManager
}
