Невозможно построить проект после создания нового bean-компонента весной ⇐ JAVA

[Anonymous]

Ну, я создал @Component для своего класса в Spring Project вот так

Код: Выделить всё

@Component
public class ClassicalMusic implements Music {
@Override
public String getSong() {
return "Hungarian Rhapsody";
}
}

В файле конфигурации applicationContext.xml я добавил путь к моим файлам, содержащим код Java.

Код: Выделить всё

Мой основной класс выглядит так:

Код: Выделить всё

public class TestSpring {

public static void main(String[] args)
{
ClassPathXmlApplicationContext context = new ClassPathXmlApplicationContext("applicationContext.xml");

Music classicalMusic = context.getBean("classicalMusic", Music.class);
System.out.println(classicalMusic.getSong());

context.close();
}
}

Ну, в результате, когда я запускаю проект, я получаю следующее сообщение.

Я искал решение и пытался добавить пустые конструкторы для этих классов. Но это не сработало.
