HTTP Status 404 – Not Found is always return

Question

I'm setting up a spring mvc project from the scratch following some tutorial. initially I configured web app to run in the tomcat. I wrote a simple controller class with request hitting to the "/". but always tomcat showing me "HTTP Status 404 – Not Found" error.

I looked many SO questions and those answers didn't work for me

1. remove the tomcat installation and reconfigure it. when hitting localhost:8080/, I'm getting tomcat home page.
2. checked the spelling of the code

web.xml file

AccountController.java file

package com.ps.springmvc.psbankapp.controllers;

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

@Controller
public class AccountController {

    @RequestMapping("/")
    public String showHomePage() {
        return "index";
    }
}

expected result should be: In the browser window "spring home page controller", which is a tag in the index.jsp file but the output is "HTTP Status 404 – Not Found" and description saying "The origin server did not find a current representation for the target resource or is not willing to disclose that one exists."

following is my folder structure.

Any help would be appreciated.

Answer 1

Im not sure but package name in <context:component-scan base-package="com.ps.springmvc.psbankApp.controllers"> must be "com.ps.springmvc. psbankapp .controllers"?
