This is my HomeController Class:

package com.luv2code.springdemo.mvc;

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

@Controller
public class HomeController {

    @RequestMapping("/")
    public String showPage() {
        return "main-menu";
    }
}

This is my Web.xml File:

<?xml version="1.0" encoding="UTF-8"?>
<web-app xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

    <!-- Spring MVC Configs -->

    <!-- Step 1: Configure Spring MVC Dispatcher Servlet -->
    <servlet>

    <servlet-mapping>
        <servlet-name>dispatcher</servlet-name>
        <url-pattern>/</url-pattern>
    </servlet-mapping>

This is main-menu.jsp file

<body>

Here is the Image of Directory

Directory Image in Eclipse

PS: I have tried all other option including switching the location, cleaning the directory and reinstalling tomcat and eclipse but all these are not working for me.Even, I changed the IDE from Eclipse to IntelliJ Idea but problem persists.

Answer

Since your servlet name is ‘dispatcher’ Spring looks for the file dispatcher-servlet.xml in the default location of your WEB-INF folder. Try renaming spring-mvc-demo-servlet.xml to dispatcher-servlet.xml and it will work.Hope it helps, Thanks
