Unbefriedigte Abhängigkeitsausnahme beim Erstellen von Beans mit Spring ⇐ Java

[Anonymous]

Ich versuche, JPA für meine Frühlingsanwendung zu verwenden. Ich habe JPATransactionManager und LocalEntityManagerFactoryBean in die AppConfig-Klasse integriert. Wenn ich nun versuche, eine der Methoden in DaoImpl aufzurufen, kann AppConfig die Klassen nicht automatisch verdrahten. Hier ist mein Code

Code: Select all

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();
}
}

AppConfig

Code: Select all

@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;
}

}

ConfirmPurchaseController

Code: Select all

@RestController
public class ConfirmPurchaseController {

private Logger logger = Logger.getLogger(ConfirmPurchaseController.class);

@Autowired
private MyService myService;

@GetMapping("/purchase")
public ResultDto confirmpurchase(HttpServletResponse response) throws ClassNotFoundException, IOException {
// Business Logic
}
}

MyService

Code: Select all

@Component
public interface MyService {
// Methods defined
}

MyServiceImpl

Code: Select all

@Service
public class MyServiceImpl implements MyService, ServletContextAware {

private ServletContext servletContext;

public void setServletContext(ServletContext servletContext) {
this.servletContext = servletContext;
}

public ServletContext getServletContext() {
return servletContext;
}

// Added the implemented methods of the MyService Interface
}

Die Ausnahme, die es auslöst, ist

Code: Select all

Caused by: org.springframework.beans.factory.UnsatisfiedDependencyException: Error creating bean with name 'myServiceImpl': Unsatisfied dependency expressed through field 'servletContext'; nested exception is org.springframework.beans.factory.NoSuchBeanDefinitionException: No qualifying bean of type 'javax.servlet.ServletContext' available: expected at least 1 bean which qualifies as autowire candidate. Dependency annotations: {@org.springframework.beans.factory.annotation.Autowired(required=true)}

und das Fehlerprotokoll ist

Irgendwelche Ideen wären für mich sehr hilfreich.

P.S.: Ich verwende die Konfiguration als Anmerkungen, kein XML
