Method Details

build

public OAuth2ClientCredentialsGrant build()

Deprecated.

Builds a new instance of OAuth2ClientCredentialsGrant using configured parameters.

clientAuthorization

public final OAuth2ClientCredentialsGrantBuilder clientAuthorization(Supplier<String> clientAuthorization,
 String authorizationType)

Provides client authorization for the OAuth 2.0 requests based on encoded authorization token and authorization type, as per [RFC6749], Section 2.3.

Parameters:

clientAuthorization - A supplier of encoded client authorization token.

authorizationType - One of the registered HTTP authentication schemes as per HTTP Authentication Scheme Registry.

Throws:

IllegalStateException - if clientAuthorization already set

clientBasicAuthorization

public final OAuth2ClientCredentialsGrantBuilder clientBasicAuthorization(Supplier<String> clientAuthorization)

Provides client authorization for the OAuth 2.0 requests based on encoded authorization token and Basic authorization type, as per [RFC6749], Section 2.3.

Parameters:

clientAuthorization - A supplier of encoded client authorization token.

Throws:

IllegalStateException - if clientAuthorization already set

clientCredentials

public final OAuth2ClientCredentialsGrantBuilder clientCredentials(Supplier<? extends Map.Entry<String,String>> clientCredentials,
 String authorizationType)

Provides client authorization for the OAuth 2.0 requests based on client credentials and authorization type, as per [RFC6749], Section 2.3.

Parameters:

clientCredentials - A supplier of client credentials.

authorizationType - One of the registered HTTP authentication schemes as per HTTP Authentication Scheme Registry.

Throws:

IllegalStateException - if clientCredentials already set

clientCredentials

public final OAuth2ClientCredentialsGrantBuilder clientCredentials(Supplier<? extends Map.Entry<String,String>> clientCredentials)

Provides client authorization for the OAuth 2.0 requests based on client credentials and Basic authorization type, as per [RFC6749], Section 2.3.

Parameters:

clientCredentials - A supplier of client credentials.

Throws:

IllegalStateException - if clientCredentials already set

refreshBefore

public final OAuth2ClientCredentialsGrantBuilder refreshBefore(Duration refreshBefore)

A period when the token should be refreshed proactively prior to its expiry.

fallbackTokenProvider

public final OAuth2ClientCredentialsGrantBuilder fallbackTokenProvider(Supplier<CompletableFuture<? extends GrantedOAuth2AccessToken>> fallbackTokenProvider)

An optional Supplier to acquire an access token before requesting it to the authorization server. If the provided GrantedOAuth2AccessToken is valid, the client doesn't request a new token.

This is supposed to be used with newTokenConsumer(Consumer) and gets executed in the following cases:

• Before the first attempt to acquire an access token.
• Before a subsequent attempt after token issue or refresh failure.

See Also:

• newTokenConsumer(Consumer)

newTokenConsumer

public final OAuth2ClientCredentialsGrantBuilder newTokenConsumer(Consumer<? super GrantedOAuth2AccessToken> newTokenConsumer)

An optional hook which gets executed whenever a new token is issued.

This can be used in combination with fallbackTokenProvider(Supplier) to store a newly issued access token which will then be retrieved by invoking the fallback token provider.
