Constructor Detail

AbstractAuthenticationToken

public AbstractAuthenticationToken(java.util.Collection<? extends GrantedAuthority> authorities)

Creates a token with the supplied array of authorities.

Parameters:

authorities - the collection of GrantedAuthoritys for the principal represented by this authentication object.

Method Detail

getAuthorities

public java.util.Collection<GrantedAuthority> getAuthorities()

Description copied from interface: Authentication

Set by an AuthenticationManager to indicate the authorities that the principal has been granted. Note that classes should not rely on this value as being valid unless it has been set by a trusted AuthenticationManager.

Implementations should ensure that modifications to the returned collection array do not affect the state of the Authentication object, or use an unmodifiable instance.

Specified by:

getAuthorities in interface Authentication

Returns:

the authorities granted to the principal, or an empty collection if the token has not been authenticated. Never null.

getName

public java.lang.String getName()

Specified by:

getName in interface java.security.Principal

isAuthenticated

public boolean isAuthenticated()

Description copied from interface: Authentication

Used to indicate to AbstractSecurityInterceptor whether it should present the authentication token to the AuthenticationManager. Typically an AuthenticationManager (or, more often, one of its AuthenticationProviders) will return an immutable authentication token after successful authentication, in which case that token can safely return true to this method. Returning true will improve performance, as calling the AuthenticationManager for every request will no longer be necessary.

For security reasons, implementations of this interface should be very careful about returning true from this method unless they are either immutable, or have some way of ensuring the properties have not been changed since original creation.

Specified by:

isAuthenticated in interface Authentication

Returns:

true if the token has been authenticated and the AbstractSecurityInterceptor does not need to present the token to the AuthenticationManager again for re-authentication.

setAuthenticated

public void setAuthenticated(boolean authenticated)

Description copied from interface: Authentication

See Authentication.isAuthenticated() for a full description.

Implementations should always allow this method to be called with a false parameter, as this is used by various classes to specify the authentication token should not be trusted. If an implementation wishes to reject an invocation with a true parameter (which would indicate the authentication token is trusted - a potential security risk) the implementation should throw an IllegalArgumentException.

Specified by:

setAuthenticated in interface Authentication

Parameters:

authenticated - true if the token should be trusted (which may result in an exception) or false if the token should not be trusted

getDetails

public java.lang.Object getDetails()

Description copied from interface: Authentication

Stores additional details about the authentication request. These might be an IP address, certificate serial number etc.

Specified by:

getDetails in interface Authentication

Returns:

additional details about the authentication request, or null if not used

setDetails

public void setDetails(java.lang.Object details)

eraseCredentials

public void eraseCredentials()

Checks the credentials, principal and details objects, invoking the eraseCredentials method on any which implement CredentialsContainer.

Specified by:

eraseCredentials in interface CredentialsContainer

equals
