沒有為依賴找到 [HrEmployeesReportOutput] 類型的合格 bean：預計至少 1 個 bean

Question

嘗試運行springboot應用程序時出現以下錯誤，我無法使用@Autowired注釋注入HrEmployeesReportOutput class，我嘗試了其他方法，但沒有奏效。

你能幫我解決這個問題嗎？

No qualifying bean of type [com.nearshoretechnology.focalpoint.interactors.hremployees.HrEmployeesReportOutput] found for dependency: expected at least 1 bean which qualifies as autowire candidate for this dependency. Dependency annotations: {@org.springframework.beans.factory.annotation.Autowired(required=true)}

@Controller
@RequestMapping("/management/hr/employees/report")
public class HrManagerEmployeeReportController {

    @Autowired
    private HrEmployeesReportOutput hrEmployeesReportPresenter;

    private HrEmployeesReportInput hrReportEmployees;

    @Secured({ HR_ADMIN, BENCH_ADMIN })
    @RequestMapping(method = RequestMethod.GET)
    public String index(Model model) {
        HrEmployeesReportForm form = new HrEmployeesReportForm();
        String username = SecurityContextHolder.getContext().getAuthentication().getName();
        form.setUsername(username);

        this.hrReportEmployees.setReportEmployeesPresenter(hrEmployeesReportPresenter);

        model.addAllAttributes(hrReportEmployees.employeeReport(form));

        return "management/hr/reports/employees";
    }

}

public interface HrEmployeesReportOutput extends InteractorOutput<HrEmployeesReportResult> {

}

public interface InteractorOutput<T> {

  Map<String, Object> generateViewModel(T result);
}

public class HrEmployeesReportResult extends BaseResult {}

public class BaseResult {}

public interface HrEmployeesReportInput {


    Map<String, Object> employeeReport(HrEmployeesReportForm form);

    void setReportEmployeesPresenter(HrEmployeesReportOutput presenter);



}

你應該至少有一個 class 實現你的HrEmployeesReportOutput接口如果你使用@ComponentScan （如果你使用spring-boot自動添加）你的class必須有注釋@Component

例如：

@Component public class HrEmployeesReportOutputImpl implements HrEmployeesReportOutput{...}
