Spring @Autowired Failed

Question

Когда я пытаюсь внедрить мой класс обслуживания с помощью @Autowired, я столкнулся некоторые проблемы

My Rest Controller:

@RestController 
@RequestMapping(value = "/SettlementType") 
public class SettlementTypeController extends Abstract4EyeController<SettlementTypeAudit, SettlementType, Integer>{ 
@Autowired 
@Qualifier("settlementTypeService") 
SettlementTypeService service; 

@Override 
public Abstract4EyeService<SettlementTypeAudit, SettlementType, Integer> get4EyeService() { 
    return service; 
} 
} 

Моя служба:

@Service("settlementTypeService") 
public class SettlementTypeService extends Abstract4EyeService<SettlementTypeAudit, SettlementType, Integer> implements IMasterFileUpload<SettlementTypeAudit, SettlementType, Integer> 
{ 
    @Autowired 
    SettlementTypeAuditRepository auditRepository; 
    //my implementations 
} 

Интерфейс:

public interface IMasterFileUpload <AuditModel extends Base4Eye, MainModel extends ReadOnlyEntity, ID extends Serializable> { 

public List<MainModel> getMainFromCollection(List<Map<String, String>> collection); 
} 

Abstract4 Видимый только услужливость:

public abstract class Abstract4EyeService<AuditModel extends Base4Eye, MainModel extends ReadOnlyEntity, ID extends Serializable> { 
@JsonIgnore 
public abstract MainModel getMainEntity(AuditModel auditModel); 
}

Я пытался Вводит Settlementype службы, но он бросает java.lang.IllegalArgumentException: Не удается установить проект project.test.rms.service.SettlementTypeService поля .test.rms.controller.SettlementTypeController.service to com.sun.proxy. Исключение $ Proxy102

Answer 1

Причина, по которой у вас возникла проблема с autwiring SettlementTypeService, объясняется тем, что Spring создает прокси этого класса внутри. Чтобы обойти это, вы можете создать интерфейс, который будет реализован в SettlementTypeService, и использовать autwire с этим интерфейсом в вашем контроллере.
