spring mvc 注解成功,DAO失败 No qualifying bean of type

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

看起来好高大上的样子,有这方面问题的可以借鉴一下,个人感觉不错。

恩,挺好,最近也遇到这种问题,看到楼主的做法,瞬间开窍,问题已解决,谢谢!

诶,你怎么解决的,求赐教

不是很明白,感觉你是注解和配制混合着用的吧,但是混着用也没有发现你在xml中配制WeatherServiceImpl和WeatherDao的bean……但是错误很明显,WeatherDao没有注入到类WeatherServiceImpl
1.如果全用注解的话,你可以在WeatherServiceImpl中weatherDao上边再使用@Qualifer注解,把类WeatherDao注入到类WeatherServiceImpl中
2.如果想用在xml中配置bean的方式,建议你再检查一下了……有没有配置bean WeatherServiceImpl ,而且bean WeatherServiceImpl 中有没有配置bean WeatherDao……
另外,多说一句,你的WeatherAction类好像也有同样的问题

哥们,你说的那种方式(全注解)我试过了,好像专门和我做对使得,还是不对,

注解的问题,和我的结构很相似

@Repository     //看看这里
public interface WeatherDao {
    public WeatherDO findByCityname(String cityname);
    public WeatherDO findByCitycode(String citycode);
    public WeatherDO findByPostcode(String postcode);
   }
问题已经解决,  配置出现了错误,
配置哪里出现了问题,出现了什么问题,具体说一下
差评 都不说怎么解决的

spring-service.xml   可以看一下这个配置文件, 修改过后的配置文件
