/**
 * Mark a class whose instance, when get injected into program, should be
 * instantiated only once per user session
 *
 * Note we make it apply to {@link ElementType#PARAMETER} by intention so
 * in a controller method we can specify a class (e.g. a collection) to indicate
 * the bean shall persist within a single request scope. E.g. if the interceptor
 * and the action handler has the same signature, the bean will NOT been
 * constructed for multiple times
