I have code based on DAO architecture with Maven on IDEA Ultimate 2024.2.2
In it, I use Spring + Hibernate to work with the MySQL database and Project Lombok to work with User entity annotations. It would seem that I set everything up according to the instructions on the Internet, but my Spring doesn’t want to start.
I'm trying to execute the following code:
public class Application {
public static void main(String[] args) {
SpringApplication.run(Application.class, args);
ApplicationContext context = new AnnotationConfigApplicationContext("applicationContext.xml");
UserDaoHibernateImpl userService = context.getBean(UserDaoHibernateImpl.class);
userService.createUsersTable();
}
}
public class Application {
public static void main(String[] args) {
SpringApplication.run(Application.class, args);
ApplicationContext context = new AnnotationConfigApplicationContext("applicationContext.xml");
UserDaoHibernateImpl userService = context.getBean(UserDaoHibernateImpl.class);
userService.createUsersTable();
}
}
but this code gives me the following exception:
Console:
Console:
Exception in thread "main" org.springframework.beans.factory.NoSuchBeanDefinitionException: No qualifying bean of type 'jm.task.core.jdbc.dao.UserDaoHibernateImpl' available

at jm.task.core.jdbc.Application.main(Application.java:17)
and even if I try to execute this code from my class for tests, I get the same exception.
