Spring Autowire in Controller not working

I am unable to get my @Autowired annotation working in my Spring REST Controller. (The controller itself works when I remove its @Autowired dependency).

I am running this on Windows under Apache Tomcat v7 with a java runtime and compile-time compiler version 1.6.

The URL is:

http://localhost:8080/bill-web/rest/article/get/chapterName/sdfsa/searchQueryInput/sadfsfa

The error is:

          org.springframework.beans.factory.BeanCreationException: 
        Error creating bean with name 'articleController': 
        Injection of autowired dependencies failed; nested exception is org.springframework.beans.factory.BeanCreationException: 
        Could not autowire field: 
    private org.ieee.bill.services.ArticleService org.ieee.bill.web.controller.ArticleController.articleService; 

nested exception is org.springframework.beans.factory.NoSuchBeanDefinitionException: 
        No qualifying bean of type [org.ieee.bill.services.ArticleService] 
        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)}
