Interface UserDetails

All Superinterfaces:

Serializable

All Known Subinterfaces:

LdapUserDetails

All Known Implementing Classes:

LdapUserDetailsImpl, User

public interface UserDetails
extends Serializable

Provides core user information.

Implementations are not used directly by Acegi Security for security purposes. They simply store user information which is later encapsulated into Authentication objects. This allows non-security related user information (such as email addresses, telephone numbers etc) to be stored in a convenient location.

Concrete implementations must take particular care to ensure the non-null contract detailed for each method is enforced. See User for a reference implementation (which you might like to extend).

Concrete implementations should be immutable (value object semantics, like a String). This is because the UserDetails will be stored in caches and as such multiple threads may use the same instance.
