1. Verwenden Sie das Laui-Framework, um die Berechtigungsanmeldung zu implementieren und das Baummenü anzuzeigen.
1. Geben Sie zunächst die vom Laui-Framework benötigten Pakete an
2. Erstellen Sie die für die Anzeige des Baummenüs erforderlichen Tabellen mit Zwei-Sterne-Berechtigungen und die für Vorgänge erforderliche Buchtyptabelle
Benutzertabelle t_xm_user
Baummenü mit der Anzeige der erforderlichen Berechtigungen Tabelle t_book_menu
Zwischenautoritätstabelle t_usermenuid
Buchtyptabelle t_book_category2
Bereiten Sie das erforderliche Paket-Toolkit im folgenden Code vor:
https://pan.baidu.com /s /1XnwIoJQUDyw0cJads5Pddw
Konfigurieren Sie die MySQL-Datenbankverbindung im Projekt
3. Berechtigungsanmeldung
