Кажется, что-то не так с автопроводкой с пружиной, когда он пытается создать боб private UserService userService;
.Для справки я прошел через них.
Не удалось внедрить зависимостей с автопроводкой;
context: component-scan "не связан
Не удалось внедрить автоматические зависимости при попытке доступа к dao bean
Это не решило мою проблему, потому что у меня уже есть такие в моих кодах. Но из журнала ошибок,Может также быть проблема, связанная с созданием шаблона hibernate, потому что он находится во вложенном списке ошибок. Я все еще пробую его в течение долгого времени, но не получаю никакого вывода. Может кто-нибудь объяснить, почему он показывает неудачную инъекцию? Потому что я уже следовал правилам, И некоторые ссылки выше, которые не решают мою проблему. Спасибо.
