Method Detail

equals

public boolean equals(Object obj)
Specified by:
equals in interface Principal
Overrides:
equals in class AbstractAuthenticationToken

getCredentials

public Object getCredentials()
Always returns an empty String

Specified by:
getCredentials in interface Authentication
Returns:
an empty String

getKeyHash

public int getKeyHash()

getPrincipal

public Object getPrincipal()
Description copied from interface: Authentication
The identity of the principal being authenticated. In the case of an authentication request with username and password, this would be the username. Callers are expected to populate the principal for an authentication request.

The AuthenticationManager implementation will often return an Authentication containing richer information as the principal for use by the application. Many of the authentication providers will create a UserDetails object as the principal.

Specified by:
getPrincipal in interface Authentication
Returns:
the Principal being authenticated or the authenticated principal after authentication.
