Package org.springframework.security.core.userdetails

Interface UserDetails

  • All Superinterfaces:
    java.io.Serializable
    All Known Implementing Classes:
    User
    public interface UserDetails
extends java.io.Serializable
    Provides core user information.

    Implementations are not used directly by Spring 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 or use in your code).
