org.springframework.beans.factory.NoSuchBeanDefinitionException: No matching解決方案

今天寫一個接口，所有的都寫完了後來測試。整個項目是用spring-mvc的框架，使用ibatis做數據庫層操作。

用jetty:run啓動時老報錯。

指向的是我的一個dao類bean找不到定義，我明明寫了

@Autowired private ApiCouponPresentDao apiCouponPresentDao; 注入代碼的呀，一直沒想起來哪裏有錯。

錯誤信息是：

org.springframework.beans.factory.BeanCreationException: Error creating bean with name 

'apiWechatService': Injection of autowired dependencies failed; nested exception is 

org.springframework.beans.factory.BeanCreationException: Could not autowire field: private 

com.tongcard.api.services.ApiCouponService 

com.tongcard.api.services.impl.ApiWechatServiceImpl.apiCouponService; nested exception is 

org.springframework.beans.factory.BeanCreationException: Error creating bean with name 

'apiCouponService': Injection of autowired dependencies failed; nested exception is 

org.springframework.beans.factory.BeanCreationException: Could not autowire field: private 

com.tongcard.api.daos.ApiCouponPresentDao 

com.tongcard.api.services.impl.ApiCouponServiceImpl.apiCouponPresentDao; nested exception is 

org.springframework.beans.factory.NoSuchBeanDefinitionException: No matching bean of type 

[com.tongcard.api.daos.ApiCouponPresentDao] found for dependency: expected at least 1 bean 

which qualifies as autowire candidate for this dependency. Dependency annotations:

後來查找其他的類似引用的bean,搜索後發現在spring-biz.xml裏面有配置，而這個類是我新加的，我忘記寫上配置了。

於是在配置文件中加入這個新的dao的定義後，再啓動就正常了。spring-mvc使用還不熟，不過這一點都忘記了的確不應該，記錄一下。
