我收到错误消息“考虑定义类型的bean”

Question

主要服务类别

@Service
public class MainService {

@Autowired
HouseRepository repository;

@Autowired
HouseDtoConverter converter;

public House addNewHouse(HouseDTO houseDTO) {

House h = converter.convert(houseDTO);
repository.save(h);

return h;``
}

public Iterable<House> getAllHouses() {
return repository.findAll();
 }
}

主控制器类

@RestController    // This means that this class is a Controller
@RequestMapping("/demo")
public class MainController {

@Autowired
MainService service;

@RequestMapping(value = "/add", method = RequestMethod.POST) // Map ONLY GET Requests
@ResponseBody
public House addNewHouse (@RequestBody HouseDTO houseDTO) {
return service.addNewHouse(houseDTO);
}

@RequestMapping(value="/all", method = RequestMethod.GET)
@ResponseBody
public Iterable<House> getAllHouses() {
// This returns a JSON or XML with the houses
return service.getAllHouses();
}

和堆栈跟踪： 说明：

vikings.service.MainService中的字段存储库需要找不到类型为'vikings.repository.HouseRepository'的bean。

注入点具有以下注释：     -@ org.springframework.beans.factory.annotation.Autowired（required = true）

操作：

考虑在您的配置中定义类型为“ vikings.repository.HouseRepository”的bean。

那是我的SpringBootApplication

@Component
@SpringBootApplication
public class SpringBoot11Application {

    public static void main(String[] args) {
        SpringApplication.run(SpringBoot11Application.class, args);
    }
}
