spring配置shiro为什么报错Error creating bean with name？

启动的时候就报错

部分错误信息：

org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'shiroFilter' defined in class path resource [spring-shiro-web.xml]: Cannot resolve reference to bean 'securityManager' while setting bean property 'securityManager'; nested exception is org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'securityManager' defined in class path resource [spring-shiro-web.xml]: Cannot resolve reference to bean 'userRealm' while setting bean property 'realm'; nested exception is org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'userRealm' defined in class path resource [spring-shiro-web.xml]: Cannot resolve reference to bean 'userService' while setting bean property 'userService'; nested exception is org.springframework.beans.factory.NoSuchBeanDefinitionException: No bean named 'userService' is defined
