启动tomcat错误 找不到bean

org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'itemController': Injection of autowired dependencies failed; nested exception is org.springframework.beans.factory.BeanCreationException: Could not autowire field: private com.taotao.serviceimpl.ItemServiceImpl com.taotao.controller.ItemController.itemService; nested exception is org.springframework.beans.factory.NoSuchBeanDefinitionException: No qualifying bean of type [com.taotao.serviceimpl.ItemServiceImpl] found for dependency: expected at least 1 bean which qualifies as autowire candidate for this dependency.

经过这么久的研究上面错误的根本原因是注入问题，注意autowired或set方法

is not writable or has an invalid setter method

这个也是一样的道理，检查appication xml文件有无错误
