一運行Tomcat站點就報錯，

在使用SSM(Spring+Spring MVC+MyBatis)框架情況下、web.xml配置沒有問題的情況下,發現：XxxService沒有使用"註解",

改了之後,要在XxxController中加上註解@Resource，機器才能找到對應XxxService類

 

 (一)以上這張或者(二)以下這張  [一樣的效果吧,且都不會報異常]

還有另一種情況：發生在spring的配置文件問題（我的發生在“spring-service”配置文件的"context:component-scan"標籤，若你發生的不是這個文件，請到其他的文件看看，確認下package路徑有沒有問題【spring-dao和spring-web】）:

 

 

對我的項目而言，應該是： 

借鑑文章：

（1）、嚴重: StandardWrapper.Throwable

（2）、SpringMVC+Mybatis+Spring整合中org.springframework.beans.factory.BeanCreationException錯誤分析【發生在context:component-scan標籤】

（3）、啓動服務的時候，出現錯誤：StandardWrapper.Throwable

補充：Spring MVC參數的傳遞與接收

詳細：出現org.springframework.beans.factory.NoSuchBeanDefinitionException 的解決思路

看也可能是spring配置文件的名字問題：報錯：org.springframework.beans.factory.NoSuchBeanDefinitionException: No bean nam
