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

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
