Subject.getPrincipals介绍

[英]Returns this Subject's principals (identifying attributes) in the form of a PrincipalCollection or null if this Subject is anonymous because it doesn't yet have any associated account data (for example, if they haven't logged in).

The word "principals" is nothing more than a fancy security term for identifying attributes associated with a Subject, aka, application user. For example, user id, a surname (family/last name), given (first) name, social security number, nickname, username, etc, are all examples of a principal.
