context - the context that holds authorization-specific state for the client

Returns:

the OAuth2AuthorizedClient or null if authorization (or re-authorization) is not supported

setAccessTokenResponseClient

public void setAccessTokenResponseClient(OAuth2AccessTokenResponseClient<OAuth2ClientCredentialsGrantRequest> accessTokenResponseClient)

Sets the client used when requesting an access token credential at the Token Endpoint for the client_credentials grant.

Parameters:

accessTokenResponseClient - the client used when requesting an access token credential at the Token Endpoint for the client_credentials grant

setClockSkew

public void setClockSkew(java.time.Duration clockSkew)

Sets the maximum acceptable clock skew, which is used when checking the access token expiry. The default is 60 seconds. An access token is considered expired if it's before Instant.now(this.clock) - clockSkew.

Parameters:

clockSkew - the maximum acceptable clock skew

setClock

public void setClock(java.time.Clock clock)

Sets the Clock used in Instant.now(Clock) when checking the access token expiry.

Parameters:

clock - the clock
