Неудовлетворенное исключение зависимости при создании bean-компонентов с использованием Spring ⇐ JAVA

[Anonymous]

Я пытаюсь использовать JPA для своего весеннего приложения. Я интегрировал JPATransactionManager и LocalEntityManagerFactoryBean в класс AppConfig. Теперь, когда я пытаюсь вызвать один из методов DaoImpl, AppConfig не может автоматически связать классы. Вот мой код

Код: Выделить всё

Test Class

public class Test {
public static void main(String[] args) {
AnnotationConfigApplicationContext context =
new AnnotationConfigApplicationContext(AppConfig.class);

BbDao personService = context.getBean(BbDao.class);
personService.getDealByDealId("0194541605021NJMAPFU");
context.close();
}
}

Конфигурация приложения

@Configuration
@EnableWebMvc
@EnableTransactionManagement
@ComponentScan(basePackages = "net.bb.spring")
public class AppConfig{

@Bean
public LocalEntityManagerFactoryBean getEntityManagerFactoryBean() {
LocalEntityManagerFactoryBean factoryBean = new LocalEntityManagerFactoryBean();
factoryBean.setPersistenceUnitName("MyPersistence");
return factoryBean;
}

@Bean
public JpaTransactionManager geJpaTransactionManager() {
JpaTransactionManager transactionManager = new JpaTransactionManager();
transactionManager.setEntityManagerFactory(getEntityManagerFactoryBean().getObject());
return transactionManager;
}

}

@RestController

@Autowired

@GetMapping("/purchase")

// Business Logic
}
}

Мой сервис

@Service

// Added the implemented methods of the MyService Interface

Исключением, которое он выдает, является

Любые идеи будут для меня очень полезны.

P.S: я использую конфигурацию в виде аннотаций, а не XML < /п>
