No mapping found for HTTP request with URL ___ in DispatcherServlet with name ___

I have been searching a way to fix this error but couldn't find the answer. Kept getting this error:

Apr 06, 2018 1:40:36 PM org.springframework.web.servlet.DispatcherServlet noHandlerFound

WARNING: No mapping found for HTTP request with URI [/spring-tutorial/] in DispatcherServlet with name 'offers'

I am running on JDK 1.8, tomcat 8.0, and running on the latest eclipse IDE.

My web.xml

    </bean>
</beans>

My OffersController.java

package com.emenpy.spring.web.controllers;

import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;

@Controller
public class OffersController {
    
    @RequestMapping("/")
    public String showHome() {
        return "home";
    }

}

And my home.jsp

<html>
    <body>
        <h2>Hello World!</h2>
    </body>
</html>

Here is my directory tree: enter image description here

Your jsp should be called "home.jsp" instead of "index.jsp"

your package name in scan is 

<context:component-scan 
        base-package="com.emenpy.spring.web.controllers">
</context:component-scan>

when it should be as your directory tree shows

<context:component-scan 
        base-package="com.cuong.spring.web.controllers">
</context:component-scan>

as the scaning didn't find your controller the mapping wasn't done
