Class JwtAccessTokenConverter

java.lang.Object

org.springframework.security.oauth2.provider.token.store.JwtAccessTokenConverter

All Implemented Interfaces:

org.springframework.beans.factory.InitializingBean, AccessTokenConverter, TokenEnhancer

public class JwtAccessTokenConverter
extends Object
implements TokenEnhancer, AccessTokenConverter, org.springframework.beans.factory.InitializingBean

Helper that translates between JWT encoded token values and OAuth authentication information (in both directions). Also acts as a TokenEnhancer when tokens are granted.

JwtAccessTokenConverter

public JwtAccessTokenConverter()

Method Detail

setAccessTokenConverter

public void setAccessTokenConverter(AccessTokenConverter tokenConverter)

Parameters:

tokenConverter - the tokenConverter to set

getAccessTokenConverter

public AccessTokenConverter getAccessTokenConverter()

Returns:

the tokenConverter in use

convertAccessToken

public Map<String,?> convertAccessToken(OAuth2AccessToken token,
                               OAuth2Authentication authentication)

Specified by:

convertAccessToken in interface AccessTokenConverter

Parameters:

token - an access token

authentication - the current OAuth authentication

Returns:

a map representation of the token suitable for a JSON response

extractAccessToken

public OAuth2AccessToken extractAccessToken(String value,
                                   Map<String,?> map)

Description copied from interface: AccessTokenConverter

Recover an access token from the converted value. Half the inverse of AccessTokenConverter.convertAccessToken(OAuth2AccessToken, OAuth2Authentication).

Specified by:

extractAccessToken in interface AccessTokenConverter

Parameters:

value - the token value

map - information decoded from an access token

Returns:

an access token

extractAuthentication

public OAuth2Authentication extractAuthentication(Map<String,?> map)

Description copied from interface: AccessTokenConverter

Recover an OAuth2Authentication from the converted access token. Half the inverse of AccessTokenConverter.convertAccessToken(OAuth2AccessToken, OAuth2Authentication).

Specified by:

extractAuthentication in interface AccessTokenConverter

Parameters:

map - information decoded from an access token

Returns:

an authentication representing the client and user (if there is one)

getKey

public Map<String,String> getKey()

Get the verification key for the token signatures.

Returns:

the key used to verify tokens

setSigningKey

public void setSigningKey(String key)

Sets the JWT signing key. It can be either a simple MAC key or an RSA key. RSA keys should be in OpenSSH format, as produced by ssh-keygen.

Parameters:

key - the key to be used for signing JWTs.

isPublic

public boolean isPublic()

Returns:

true if the signing key is a public key

setVerifierKey

public void setVerifierKey(String key)

The key used for verifying signatures produced by this class. This is not used but is returned from the endpoint to allow resource servers to obtain the key. For an HMAC key it will be the same value as the signing key and does not need to be set. For and RSA key, it should be set to the String representation of the public key, in a standard format (e.g. OpenSSH keys)

Parameters:

key - the signature verification key (typically an RSA public key)

enhance

public OAuth2AccessToken enhance(OAuth2AccessToken accessToken,
                        OAuth2Authentication authentication)

Description copied from interface: TokenEnhancer

Provides an opportunity for customization of an access token (e.g. through its additional information map) during the process of creating a new token for use by a client.

Specified by:

enhance in interface TokenEnhancer

Parameters:

accessToken - the current access token with its expiration and refresh token

authentication - the current authentication including client and user details

Returns:

a new token enhanced with additional information

encode

protected String encode(OAuth2AccessToken accessToken,
            OAuth2Authentication authentication)

decode

protected Map<String,Object> decode(String token)

afterPropertiesSet

public void afterPropertiesSet()
                        throws Exception

Specified by:

afterPropertiesSet in interface org.springframework.beans.factory.InitializingBean

Throws:

Exception
