Java Spring Web Application - No mapping found for HTTP request

Question

i spend a few hours fighting with my problem, but with no big result, maybe someone will help me :)

My project look like this:

I want to use a library to draw a chart from this tutorial: FusionCharts

I got error message this:

09-Jan-2018 21:56:22.304 WARNING [http-nio-8080-exec-1] org.springframework.web.servlet.PageNotFound.noHandlerFound No mapping found for HTTP request with URI [/] in DispatcherServlet with name 'spring' 09-Jan-2018 21:56:22.323 WARNING [http-nio-8080-exec-3] org.springframework.web.servlet.PageNotFound.noHandlerFound No mapping found for HTTP request with URI [/] in DispatcherServlet with name 'spring' 09-Jan-2018 21:56:22.465 WARNING [http-nio-8080-exec-5] org.springframework.web.servlet.PageNotFound.noHandlerFound No mapping found for HTTP request with URI [/] in DispatcherServlet with name 'spring'

Files FusionCharts, fusioncharts.charts.js and fusioncharts.js are from library.

Home Controller Code:

package com.charts.controller;
import java.io.IOException;
import javax.servlet.ServletException;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
import org.springframework.web.servlet.ModelAndView;
import org.springframework.web.servlet.mvc.Controller;

public class HomeController implements Controller {
    @Override
    public ModelAndView handleRequest(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {
        return new ModelAndView("index");
    }

    public String chartmaker(){
        FusionCharts lineChart = new FusionCharts (
                "line",// chartType
                "chart1",// chartId
                "600","350",// chartWidth, chartHeight
                "chart",// chartContainer
                "jsonurl",// dataFormat
                "data.json"
        );
        return lineChart.render();
    }

}

</web-app>

When i run a project, i got this message:

When i go to the http://localhost:8080/welcome.html i got a clear screen and this library doesn't draw any chart or something like that.

My configuration files are properly like web.xml or spring-servlet.xml ? I will be grateful for any advices

You shouldn't instantiate and/or call methods on your Controller class from your JSP. Your Controller handler methods should return a view name which corresponds to a view (viewname.jsp). It might help to search for some Spring MVC tutorials and work through a getting started app first, as your current usage seems a bit confused. — Kevin Hooke
You might also want to look at creating a new Spring MVC app with Spring Boot, as the configuration is vastly simplified (no need for xml config anymore) — Kevin Hooke
In Controller i return a view index.jsp like that: @RequestMapping("/index") public ModelAndView hello() { return new ModelAndView("index"); }, I did it a properly? — user7061656

I suggest you annotate your HomeController class with @Controller, and inside a method with any name (ex. public String showIndex() { return "index"; } ). Annotate that method with @GetMapping("/") should work.
