使用spring 的@Autowired注解引起错误org.springframework.beans.factory.BeanCreationExceptio

[tdy2837]

我要创建一个springmvc项目，使用了@Autowired注解引起下面的错误

org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'clothesController': Injection of autowired dependencies failed; nested exception is org.springframework.beans.factory.BeanCreationException: Could not autowire field: private com.clothes.service.ClothesService com.clothes.controller.ClothesController.clothesService; nested exception is org.springframework.beans.factory.NoSuchBeanDefinitionException: No matching bean of type [com.clothes.service.ClothesService] found for dependency: expected at least 1 bean which qualifies as autowire candidate for this dependency.

意思好像是ClothesService这个无法实例化，导致无法创建clothesController。

@Service("clothesService")
@Transactional
public class ClothesServiceImpl extends CommonServiceImpl implements ClothesService{

}

@Controller
@RequestMapping("/clothesController")
public class ClothesController {

private static final Logger logger=Logger.getLogger(ClothesController.class);

@Autowired
private ClothesService clothesService;

private String message;

public String getMessage() {
return message;
}

public void setMessage(String message) {
this.message = message;
}

@RequestMapping(params = "clothes")
public String toMainPage(){

return "main/index";
}

}

网上查资料，说要再配置文件中加
<bean class="org.springframework.beans.factory.annotation.AutowiredAnnotationBeanPostProcessor"/>
我也加上去了，现在不清楚问题出在哪里了，求解答。

我也碰到这个问题，我还碰到注入了之后null

[qq314782718]

这个问题应该是接口的用实现类没有用@Service这个注解

[奋斗龟]

你扫描包了吗？ <context:component-scan base-package="com.gclc" />

[qq_35451912]

实现类里面注解没加

这个应该需要一个注入的工厂类 有可能是因为他的父类没有被spring管理 我们老师讲过的

re:
有重名的，spring无法确认你需要的到底是哪一个

@Service("portalArticleService")
public class PortalArticleServiceImpl extends ArticleServiceImpl implements PortalArticleService{}

@Controller
@RequestMapping(value="/article")
@Scope("prototype")
public class ArticleController {
    @Autowired
    @Qualifier("portalArticleService")
    private PortalArticleService portalArticleService;
}
