== Resolving an Authorized Client
|
||||
|
||||
The `@RegisteredOAuth2AuthorizedClient` annotation provides the capability of resolving a method parameter to an argument value of type `OAuth2AuthorizedClient`.
|
||||
This is a convenient alternative compared to accessing the `OAuth2AuthorizedClient` using the `ReactiveOAuth2AuthorizedClientManager` or `ReactiveOAuth2AuthorizedClientService`.

The `@RegisteredOAuth2AuthorizedClient` annotation is handled by `OAuth2AuthorizedClientArgumentResolver`, which directly uses a <<oauth2Client-authorized-manager-provider, ReactiveOAuth2AuthorizedClientManager>> and therefore inherits it's capabilities.

[[oauth2Client-webclient-webflux]]
|
||||
== WebClient integration for Reactive Environments
|
||||
|
||||
The OAuth 2.0 Client support integrates with `WebClient` using an `ExchangeFilterFunction`.
|
||||
|
||||
The `ServerOAuth2AuthorizedClientExchangeFilterFunction` provides a simple mechanism for requesting protected resources by using an `OAuth2AuthorizedClient` and including the associated `OAuth2AccessToken` as a Bearer Token.
|
||||
It directly uses an <<oauth2Client-authorized-manager-provider, ReactiveOAuth2AuthorizedClientManager>> and therefore inherits the following capabilities:
|
||||
|
||||
* An `OAuth2AccessToken` will be requested if the client has not yet been authorized.
|
||||
** `authorization_code` - triggers the Authorization Request redirect to initiate the flow
|
||||
** `client_credentials` - the access token is obtained directly from the Token Endpoint
|
||||
** `password` - the access token is obtained directly from the Token Endpoint
|
||||
* If the `OAuth2AccessToken` is expired, it will be refreshed (or renewed) if a `ReactiveOAuth2AuthorizedClientProvider` is available to perform the authorization
|
||||
|
||||
The following code shows an example of how to configure `WebClient` with OAuth 2.0 Client support:

=== Providing the Authorized Client

|

|
||||
=== Defaulting the Authorized Client
|
||||
|

If neither `OAuth2AuthorizedClient` or `ClientRegistration.getRegistrationId()` is provided as a request attribute, the `ServerOAuth2AuthorizedClientExchangeFilterFunction` can determine the _default_ client to use depending on it's configuration.
|
||||
|
||||
If `setDefaultOAuth2AuthorizedClient(true)` is configured and the user has authenticated using `ServerHttpSecurity.oauth2Login()`, the `OAuth2AccessToken` associated with the current `OAuth2AuthenticationToken` is used.

Please refer to JSON Web Token (JWT) Profile for OAuth 2.0 Client Authentication and Authorization Grants for further details on https://datatracker.ietf.org/doc/html/rfc7523#section-2.2[JWT Bearer] Client Authentication.
|

|
||||
The default implementation for JWT Bearer Client Authentication is `NimbusJwtClientAuthenticationParametersConverter`,
|

which is a `Converter` that customizes the Token Request parameters by adding
|

a signed JSON Web Token (JWS) in the `client_assertion` parameter.
|
||||
|

The `java.security.PrivateKey` or `javax.crypto.SecretKey` used for signing the JWS

`ClientRegistration` is a representation of a client registered with an OAuth 2.0 or OpenID Connect 1.0 Provider.
|
||||
|
||||
A client registration holds information, such as client id, client secret, authorization grant type, redirect URI, scope(s), authorization URI, token URI, and other details.
|
||||
|
||||
`ClientRegistration` and its properties are defined as follows:

A `ClientRegistration` can be initially configured using discovery of an OpenID Connect Provider's https://openid.net/specs/openid-connect-discovery-1_0.html#ProviderConfig[Configuration endpoint] or an Authorization Server's https://tools.ietf.org/html/rfc8414#section-3[Metadata endpoint].
|
||||
|
||||
`ClientRegistrations` provides convenience methods for configuring a `ClientRegistration` in this way, as can be seen in the following example:
|
||||
|
||||
====
|
||||
.Java
|
||||
[source,java,role="primary"]
|
||||
----
|
||||
ClientRegistration clientRegistration =
|
||||
ClientRegistrations.fromIssuerLocation("https://idp.example.com/issuer").build();
|
||||
----
|
||||
|
||||
.Kotlin
|
||||
[source,kotlin,role="secondary"]
|
||||
----
|
||||
val clientRegistration = ClientRegistrations.fromIssuerLocation("https://idp.example.com/issuer").build()
|
||||
----
|
||||
====
|
||||
|
||||
The above code will query in series `https://idp.example.com/issuer/.well-known/openid-configuration`, and then `https://idp.example.com/.well-known/openid-configuration/issuer`, and finally `https://idp.example.com/.well-known/oauth-authorization-server/issuer`, stopping at the first to return a 200 response.
|
||||
|
||||
As an alternative, you can use `ClientRegistrations.fromOidcIssuerLocation()` to only query the OpenID Connect Provider's Configuration endpoint.

[[oauth2Client-client-registration-repo]]
|
||||
== ReactiveClientRegistrationRepository
|
||||
|
||||
The `ReactiveClientRegistrationRepository` serves as a repository for OAuth 2.0 / OpenID Connect 1.0 `ClientRegistration`(s).
|
||||
|
||||
[NOTE]
|
||||
Client registration information is ultimately stored and owned by the associated Authorization Server.
|
||||
This repository provides the ability to retrieve a sub-set of the primary client registration information, which is stored with the Authorization Server.
|
||||
|
||||
Spring Boot 2.x auto-configuration binds each of the properties under `spring.security.oauth2.client.registration._[registrationId]_` to an instance of `ClientRegistration` and then composes each of the `ClientRegistration` instance(s) within a `ReactiveClientRegistrationRepository`.
|
||||
|
||||
[NOTE]
|
||||
The default implementation of `ReactiveClientRegistrationRepository` is `InMemoryReactiveClientRegistrationRepository`.
|
||||
|
||||
The auto-configuration also registers the `ReactiveClientRegistrationRepository` as a `@Bean` in the `ApplicationContext` so that it is available for dependency-injection, if needed by the application.

||||

[[oauth2Client-authorized-client]]
|
||||
== OAuth2AuthorizedClient
|
||||
|
||||
`OAuth2AuthorizedClient` is a representation of an Authorized Client.
|
||||
A client is considered to be authorized when the end-user (Resource Owner) has granted authorization to the client to access its protected resources.
|
||||
|
||||
`OAuth2AuthorizedClient` serves the purpose of associating an `OAuth2AccessToken` (and optional `OAuth2RefreshToken`) to a `ClientRegistration` (client) and resource owner, who is the `Principal` end-user that granted the authorization.
|
||||
|
||||
|
||||
[[oauth2Client-authorized-repo-service]]
|
||||
== ServerOAuth2AuthorizedClientRepository / ReactiveOAuth2AuthorizedClientService
|
||||
|
||||
`ServerOAuth2AuthorizedClientRepository` is responsible for persisting `OAuth2AuthorizedClient`(s) between web requests.
|
||||
Whereas, the primary role of `ReactiveOAuth2AuthorizedClientService` is to manage `OAuth2AuthorizedClient`(s) at the application-level.
|
||||
|
||||
From a developer perspective, the `ServerOAuth2AuthorizedClientRepository` or `ReactiveOAuth2AuthorizedClientService` provides the capability to lookup an `OAuth2AccessToken` associated with a client so that it may be used to initiate a protected resource request.
|
||||
|
||||

====
|
||||
|
||||
[NOTE]
|
||||
Spring Boot 2.x auto-configuration registers an `ServerOAuth2AuthorizedClientRepository` and/or `ReactiveOAuth2AuthorizedClientService` `@Bean` in the `ApplicationContext`.
|
||||
However, the application may choose to override and register a custom `ServerOAuth2AuthorizedClientRepository` or `ReactiveOAuth2AuthorizedClientService` `@Bean`.
|
||||
|
||||
The default implementation of `ReactiveOAuth2AuthorizedClientService` is `InMemoryReactiveOAuth2AuthorizedClientService`, which stores `OAuth2AuthorizedClient`(s) in-memory.
|
||||
|
||||
Alternatively, the R2DBC implementation `R2dbcReactiveOAuth2AuthorizedClientService` may be configured for persisting `OAuth2AuthorizedClient`(s) in a database.
|
||||
|
||||
[NOTE]
|
||||
`R2dbcReactiveOAuth2AuthorizedClientService` depends on the table definition described in xref:servlet/appendix/database-schema.adoc#dbschema-oauth2-client[ OAuth 2.0 Client Schema].

[[oauth2Client-authorized-manager-provider]]
|
||||
== ReactiveOAuth2AuthorizedClientManager / ReactiveOAuth2AuthorizedClientProvider
|
||||
|
||||
The `ReactiveOAuth2AuthorizedClientManager` is responsible for the overall management of `OAuth2AuthorizedClient`(s).
|
||||
|
||||
The primary responsibilities include:
|
||||
|
||||
* Authorizing (or re-authorizing) an OAuth 2.0 Client, using a `ReactiveOAuth2AuthorizedClientProvider`.
|
||||
* Delegating the persistence of an `OAuth2AuthorizedClient`, typically using a `ReactiveOAuth2AuthorizedClientService` or `ServerOAuth2AuthorizedClientRepository`.
|
||||
* Delegating to a `ReactiveOAuth2AuthorizationSuccessHandler` when an OAuth 2.0 Client has been successfully authorized (or re-authorized).
|
||||
* Delegating to a `ReactiveOAuth2AuthorizationFailureHandler` when an OAuth 2.0 Client fails to authorize (or re-authorize).
|
||||
|
||||
A `ReactiveOAuth2AuthorizedClientProvider` implements a strategy for authorizing (or re-authorizing) an OAuth 2.0 Client.
|
||||
Implementations will typically implement an authorization grant type, eg. `authorization_code`, `client_credentials`, etc.
|
||||
|
||||
The default implementation of `ReactiveOAuth2AuthorizedClientManager` is `DefaultReactiveOAuth2AuthorizedClientManager`, which is associated with a `ReactiveOAuth2AuthorizedClientProvider` that may support multiple authorization grant types using a delegation-based composite.
|
||||
The `ReactiveOAuth2AuthorizedClientProviderBuilder` may be used to configure and build the delegation-based composite.
|
||||
|
||||
The following code shows an example of how to configure and build a `ReactiveOAuth2AuthorizedClientProvider` composite that provides support for the `authorization_code`, `refresh_token`, `client_credentials` and `password` authorization grant types:
|
||||

|

return authorizedClientManager;
|

}

|
||||
val authorizedClientProvider: ReactiveOAuth2AuthorizedClientProvider = ReactiveOAuth2AuthorizedClientProviderBuilder.builder()
|

.authorizationCode()
|

val authorizedClientManager = DefaultReactiveOAuth2AuthorizedClientManager(

clientRegistrationRepository, authorizedClientRepository)
|
||||
authorizedClientManager.setAuthorizedClientProvider(authorizedClientProvider)
|
||||
return authorizedClientManager
|
||||
}
|
||||
----
|
||||
====
|
||||
|
||||
When an authorization attempt succeeds, the `DefaultReactiveOAuth2AuthorizedClientManager` will delegate to the `ReactiveOAuth2AuthorizationSuccessHandler`, which (by default) will save the `OAuth2AuthorizedClient` via the `ServerOAuth2AuthorizedClientRepository`.
|
||||
In the case of a re-authorization failure, eg. a refresh token is no longer valid, the previously saved `OAuth2AuthorizedClient` will be removed from the `ServerOAuth2AuthorizedClientRepository` via the `RemoveAuthorizedClientReactiveOAuth2AuthorizationFailureHandler`.
|
||||
The default behaviour may be customized via `setAuthorizationSuccessHandler(ReactiveOAuth2AuthorizationSuccessHandler)` and `setAuthorizationFailureHandler(ReactiveOAuth2AuthorizationFailureHandler)`.
|
||||
|
||||
The `DefaultReactiveOAuth2AuthorizedClientManager` is also associated with a `contextAttributesMapper` of type `Function<OAuth2AuthorizeRequest, Mono<Map<String, Object>>>`, which is responsible for mapping attribute(s) from the `OAuth2AuthorizeRequest` to a `Map` of attributes to be associated to the `OAuth2AuthorizationContext`.
|
||||
This can be useful when you need to supply a `ReactiveOAuth2AuthorizedClientProvider` with required (supported) attribute(s), eg. the `PasswordReactiveOAuth2AuthorizedClientProvider` requires the resource owner's `username` and `password` to be available in `OAuth2AuthorizationContext.getAttributes()`.
|
||||
|
||||
The following code shows an example of the `contextAttributesMapper`:

The `DefaultReactiveOAuth2AuthorizedClientManager` is designed to be used *_within_* the context of a `ServerWebExchange`.

When operating *_outside_* of a `ServerWebExchange` context, use `AuthorizedClientServiceReactiveOAuth2AuthorizedClientManager` instead.

A _service application_ is a common use case for when to use an `AuthorizedClientServiceReactiveOAuth2AuthorizedClientManager`.

Service applications often run in the background, without any user interaction, and typically run under a system-level account instead of a user account.
