严重: Servlet /test threw load() exception
org.springframework.beans.factory.NoSuchBeanDefinitionException: No qualifying bean of type

service注解成功，但是DAO 就是失败，下面这是代码Controller

@Controller
public class WeatherAction {
    @Autowired
    private WeatherService weatherService;
    @RequestMapping("/find")
    public @ResponseBody String find(String test){
        WeatherDO weatherDO = weatherService.findWeather(test);
        return weatherDO.getCityname();
    }
}

service

public interface WeatherService {
     public WeatherDO findWeather(String test);
}

service实现

@Service
public class WeatherServiceImpl implements WeatherService {
    @Autowired
    private WeatherDao weatherDao;
    public WeatherDO findWeather(String test) {
        if (Utils.isHowManyNumbers(6, test)) {
            return weatherDao.findByPostcode(test);
        }
        if (Utils.isHowManyNumbers(9, test)) {
            return weatherDao.findByCitycode(test);
        }
        return weatherDao.findByCityname(test);
    }
}

DAO

public interface WeatherDao {
    public WeatherDO findByCityname(String cityname);
    public WeatherDO findByCitycode(String citycode);
    public WeatherDO findByPostcode(String postcode);
   }

接下来就是配置文件web.xml
