20. @RegisteredOAuth2AuthorizedClient
Spring Security allows resolving an access token using @RegisteredOAuth2AuthorizedClient
.

A working example can be found in OAuth 2.0 WebClient WebFlux sample . |
After configuring Spring Security for OAuth2 Login or as an OAuth2 Client, an OAuth2AuthorizedClient
can be resolved using the following:
@GetMapping("/explicit")
Mono<String> explicit(@RegisteredOAuth2AuthorizedClient("client-id") OAuth2AuthorizedClient authorizedClient) {
// ...
}
This integrates into Spring Security to provide the following features:
- Spring Security will automatically refresh expired tokens (if a refresh token is present)
If an access token is requested and not present, Spring Security will automatically request the access token.
- For
authorization_code
this involves performing the redirect and then replaying the original request - For
client_credentials
the token is simply requested and saved
- For
If the user authenticated using oauth2Login()
, then the client-id
is optional. For example, the following would work:
@GetMapping("/implicit")
Mono<String> implicit(@RegisteredOAuth2AuthorizedClient OAuth2AuthorizedClient authorizedClient) {
// ...
}
This is convenient if the user always authenticates with OAuth2 Login and an access token from the same authorization server is needed.
