public @interface EnableOAuth2Client

Enable configuration for an OAuth2 client in a web application that uses Spring Security and wants to use the Authorization Code Grant from one or more OAuth2 Authorization servers. To take advantage of this feature you need a global servlet filter in your application of the DelegatingFilterProxy that delegates to a bean named "oauth2ClientContextFilter". Once that filter is in place your client app can use another bean provided by this annotation (an AccessTokenRequest) to create an OAuth2RestTemplate, e.g.

 @Configuration
 @EnableOAuth2Client
 public class RemoteResourceConfiguration {
 
        @Bean
  public OAuth2RestOperations restTemplate(OAuth2ClientContext oauth2ClientContext) {
                return new OAuth2RestTemplate(remote(), oauth2ClientContext);
        }
 
 }
 

Client apps that use client credentials grants do not need the AccessTokenRequest or the scoped RestOperations (the state is global for the app), but they should still use the filter to trigger the OAuth2RestOperations to obtain a token when necessary. Apps that use password grants need to set the authentication properties in the OAuth2ProtectedResourceDetails before using the RestOperations, and this means the resource details themselves also have to be per session (assuming there are multiple users in the system).
