OAuth2LoginReactiveAuthenticationManager (spring-security-docs 5.8.11 API)

java.lang.Object
- org.springframework.security.oauth2.client.authentication.OAuth2LoginReactiveAuthenticationManager

All Implemented Interfaces:

ReactiveAuthenticationManager
```
public class OAuth2LoginReactiveAuthenticationManager
extends java.lang.Object
implements ReactiveAuthenticationManager
```
An implementation of an AuthenticationProvider for OAuth 2.0 Login, which leverages the OAuth 2.0 Authorization Code Grant Flow. This AuthenticationProvider is responsible for authenticating an Authorization Code credential with the Authorization Server's Token Endpoint and if valid, exchanging it for an Access Token credential.
It will also obtain the user attributes of the End-User (Resource Owner) from the UserInfo Endpoint using an OAuth2UserService, which will create a Principal in the form of an OAuth2User. The OAuth2User is then associated to the OAuth2LoginAuthenticationToken to complete the authentication.

Since:

5.1
