Обновление расписания в весенней загрузке

0 голосов
/ 14 октября 2019

Я новичок в весенней загрузке и сейчас работаю над проектом расписания. В моей системе добавление и удаление timeTable работает правильно, а обновление timeTable - нет. Когда я добавляю timeTable, он создает (# timeslots * #days строк в таблице базы данных, и у всех этих строк есть общий код). Когда я выбираю edit, http://localhost:8080/timeTableMapping/edit/116 передается как URL (116 - общий код). Что мне нужно сделать, это загрузить правильную тему в поле соответствующего и сохранить правильно обновленные данные в базе данных. Кто-нибудь может мне помочь. thx
