После этого учебного пособия я создал веб-приложение, но при развертывании tomcat выдает ошибку:
org.springframework.beans.factory.NoSuchBeanDefinitionException: No matching bean of type [org.example.repository.UserRepository] found for dependency: expected at least 1 bean which qualifies as autowire candidate for this dependency. Dependency annotations: {@org.springframework.beans.factory.annotation.Autowired(required=true)}
компилируется нормально с maven, но не нашел что вызывает ошибку при развертывании.
Ниже приводится моя сеть. xml:
