Org.springframework.beans.factory.BeanDefinitionStoreException: неверное определение bean-компонента с именем «bookDao», ⇐ JAVA

[Anonymous]

Я только начал изучать какой-то проект Springboot, вот проблема, которую я понятия не имею, как ее решить, и даже не знаю, что происходит.
BookDao.java р>

book.setId(10);
book.setType("a");

@Test

Book book = new Book();
book.setType("b");
book.setName("b");
book.setDescription("b");
System.out.println(bookDao.insert(book));
}

}

Это почти все, что у меня есть на данный момент, и ниже я получаю неправильные ситуации
