Java Spring 问题求解

@Component
public class ExpressOrderThreeSectionsCodeTask implements Callable {

    private String orderNo;
    private String countryCode;
    private String provinceName;
    private String cityName;
    private String districtName;
    private String address;

    @Autowired
    private IExpressOrderApiService expressOrderApiService;

    public ExpressOrderThreeSectionsCodeTask(String orderNo, String countryCode, String provinceName,
                                             String cityName, String districtName, String address) {
        this.orderNo = orderNo;
        this.countryCode = countryCode;
        this.provinceName = provinceName;
        this.cityName = cityName;
        this.districtName = districtName;
        this.address = address;
    }
...
}

代码如上，当我使用了 @Component 注解时 为什么 ExpressOrderThreeSectionsCodeTask 这个构造函数会报错，被 Spring 管理的类不能有自己的私有属性或者构造函数嘛？
