Я хотел сделать небольшое приложение, используя весну и спящий режим, и я столкнулся с вышеупомянутым, я просмотрел ответы, связанные с указанным выше вопросом, но я не смог его решить, используя те ответы.Когда я запускаю tomcat, я получаю ошибку NoSuchBeanCreation
Структура Пакет
- com.library.bean
- com.library.controller
- com.library.dao
- com.library.service
Файлы под каждая упаковка
В com.library.bean - LoginBean.java
В com.library.controller - LoginController.java
В com.library.dao - DataAccessObject.java
В com.library.service - UserCreditentialsService.java
К сожалению для размещения длинного кода
