@org.springframework.beans.factory.annotation.Autowired(required=true)

錯誤：

org.springframework.beans.factory.BeanCreationException: Error creating bean with name ‘paymentOrderController’: Injection of autowired dependencies failed; nested exception is org.springframework.beans.factory.BeanCreationException: Could not autowire field: private com.chaoge.service.paymentOrderService com.chaoge.controller.paymentOrderController.pos; nested exception is org.springframework.beans.factory.NoSuchBeanDefinitionException: No qualifying bean of type [com.chaoge.service.paymentOrderService] found for dependency: expected at least 1 bean which qualifies as autowire candidate for this dependency. Dependency annotations: {@org.springframework.beans.factory.annotation.Autowired(required=true)}

由於自己平常做項目時喜歡喜歡各種嘗試，所有特別多奇葩錯誤！今天遇到了這個問題搞了半天，在網上也看了下別人的錯誤，和我的有點不一樣，突然想到配置springMvc只配置了controller掃描注入，未配置service掃描注入，所以使用@Autowired無法注入報錯!分享一下，也給以後留個答案！
在springMvc文件中配置以下代碼就可以了:

解決方法：

<!-- 掃描controller,service（controller,service層注入） -->
<context:component-scan base-package="com.chaoge.controller"/>
<context:component-scan base-package="com.chaoge.service"/>
