Method Detail

getDetails

public Object getDetails()

Description copied from class: AbstractAuthenticationToken

Subclasses should override if they wish to provide additional details about the authentication event.

Specified by:

getDetails in interface Authentication

Overrides:

getDetails in class AbstractAuthenticationToken

Returns:

always null

setDetails

public void setDetails(Object details)

setAuthenticated

public void setAuthenticated(boolean isAuthenticated)

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.

Parameters:

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

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 to this method unless they are either immutable, or have some way of ensuring the properties have not been changed since original creation.

Returns:

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

getAuthorities

public 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.

Returns:

the authorities granted to the principal, or null if authentication has not been completed

getCredentials

public Object getCredentials()

Description copied from interface: Authentication

The credentials that prove the principal is correct. This is usually a password, but could be anything relevant to the AuthenticationManager. Callers are expected to populate the credentials.

Returns:

the credentials that prove the identity of the Principal

getPrincipal

public Object getPrincipal()

Description copied from interface: Authentication

The identity of the principal being authenticated. This is usually a username. Callers are expected to populate the principal.

Returns:

the Principal being authenticated
