Ich habe eine unter Projektstruktur.Spring Data Jpa Erste Schritte
und ich habe eine Hauptfeder-Boot-Anwendungsklasse, wie unten
@SpringBootApplication
@ComponentScan(basePackages={"com.portal.*"})
@EnableJpaRepositories(basePackages={"com.portal.repository"})
public class Application {
@Autowired
private ResourceDataService resourceDataService;
public static void main(String[] args) {
SpringApplication.run(Application.class, args);
}
@RequestMapping("/")
public void list(){
resourceDataService.find();
}
}
und unterstützenden Klassen sind wie folgt
@Service
public class ResourceDataService {
private CalenderRepo resourceRepo;
@Autowired
public ResourceDataService(CalenderRepo resourceRepo){
this.resourceRepo = resourceRepo;
}
public void find(){
resourceRepo.findAll();
}
@Repository
public interface CalenderRepo extends CrudRepository<Calendar, Long> {
Calendar findOneByCalendarMonth(String calendar_Month);
}
Es wirft einen unten Fehler.
[main] ationConfigEmbeddedWebApplicationContext : Exception encountered during context initialization - cancelling refresh attempt: org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'application': Injection of autowired dependencies failed; nested exception is org.springframework.beans.factory.BeanCreationException: Could not autowire field: private com.portal.services.ResourceDataService main.Application.resourceDataService; nested exception is org.springframework.beans.factory.UnsatisfiedDependencyException: Error creating bean with name 'resourceDataService' defined in file [C:\Users\M1023004\workspaceNew\MongoLab\Project\target\classes\com\portal\services\ResourceDataService.class]: Unsatisfied dependency expressed through constructor argument with index 0 of type [com.portal.repository.CalenderRepo]: : Error creating bean with name 'calenderRepo': Invocation of init method failed; nested exception is java.lang.IllegalArgumentException: Not an managed type: class java.util.Calendar; nested exception is org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'calenderRepo': Invocation of init method failed; nested exception is java.lang.IllegalArgumentException: Not an managed type: class java.util.Calendar
Kann mir jemand helfen, diesen Fehler zu beheben.
Auch wenn Sie eine gute Referenz Dokumentation für den Frühling Daten jpa haben, bitte teilen Sie hier.

Ich schlage vor, Sie 'Application' bewegen alle Anmerkungen zu' com.portal' und entfernen, aber ' @ SpringBootApplication'. Dadurch werden automatisch alle Funktionen aktiviert, die Sie benötigen. Wenn Sie sie in ein anderes Paket verschieben, wird es viel schwieriger, die Dinge zum Laufen zu bringen. –
Ich habe es versucht .. und immer noch kein Glück .. Ich habe meinen Beitrag bearbeitet. – Geek
Anstatt ein Snippet zu posten, geben Sie den vollständigen Stack-Trace ein. Die Nachricht ist klar, übrigens verwenden Sie den falschen 'Kalender' Sie verwenden' java.util.Calendar' anstelle Ihres eigenen Typs -> 'Kein verwalteter Typ: class java.util.Calendar' Reparieren Sie Ihre Repo-Definition. –
