you have forgot to add <context:annotation-config/> in dispatcher-servlet.xml, which activates various annotation's like: @Controller, @Component, @Service, @Repository ..

and make spring dispatcher as a Default Servlet by mapping to /, So that every request will endup in dispatcher servlet.

<servlet>
   <servlet-name>dispatcher</servlet-name>
   <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class> 
</servlet>
<servlet-mapping>
   <servlet-name>dispatcher</servlet-name>
   <url-pattern>/</url-pattern>  
</servlet-mapping>
