Annotation Interface Username
The
Username annotation is used to mark a field in a user entity
class that represents the username of the user.
This annotation helps identify the field that stores the user's login
identifier, typically used during the authentication process.
When applied to a field, the Username annotation signifies
that the field holds the user's username, which may be used to locate the
user in the system, validate login credentials, or associate the user with
various security-related processes.
This annotation is primarily used by the SecurityUtil class
to reflectively identify the field that contains the username in the
user entity, ensuring that the correct information is used when
authenticating users or fetching user details from the system.
It is expected that the annotated field will hold a unique, user-specific identifier, often required during login or user lookup in the system.
