新手配置Maven环境时 :配置报错
新手配置Maven环境时，报错org.springframework.beans.factory.BeanCreationException: Error creating bean with name
初学maven，但是又比较急，已经弄了很久了，但是环境还没有配出来，有没有高手帮忙解决一下呢？？
org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'manangerController': Injection of autowired dependencies failed; nested exception is org.springframework.beans.factory.BeanCreationException: Could not autowire field: private org.ssm.dufy.service.IManagerService org.ssm.dufy.web.ManangerController.managerService; nested exception is org.springframework.beans.factory.NoSuchBeanDefinitionException: No qualifying bean of type [org.ssm.dufy.service.IManagerService] found for dependency: expected at least 1 bean which qualifies as autowire candidate for this dependency.

web.xml里面的ContextLoaderListener没配置？
<listener> <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class> </listener>######如果有高手指教的话能远程帮忙看下是最好的，非常感谢，在线等！！！######Controller注入service的时候出错了，原因你的service对应的bean不存在，检查一下你的配置文件应该是没有扫描到service和实例化service的bean。######这个不是maven的问题,是Spring注入这块儿出错了,ManagerController里的managerService注入错误,找不到Service,这里需要检查代码~~######感觉 你那个类 是不是把构造private了######org.ssm.dufy.service.IManagerService 检查这个接口的实现类 是否添加@Service注解
<context:component-scan base-package="org.ssm.dufy.service"> 这句是扫描base-package下面所有被 @Component 注解的类， @Service , @Controller 里面都被 @Component注解######引用来自“melon_jj”的评论
这个不是maven的问题,是Spring注入这块儿出错了,ManagerController里的managerService注入错误,找不到Service,这里需要检查代码~~还有什么疑问吗？可以直接Q我3474203856 详细交流一下。
