Controller:

package com.controller;

import org.springframework.stereotype.Controller;
import org.springframework.ui.Model;
import org.springframework.web.bind.annotation.RequestMapping;
@Controller    
    public class CustomController {

        @RequestMapping(value="/",params="abcd")
        public void test() {
            System.out.println("in test method of conroller");
        }
        }

what I was trying is to send a request from html page to spring controller and return an JSON from spring controller to the requesting page. But now I am getting this error after to build through tomcat,

org.springframework.web.servlet.PageNotFound noHandlerFound
WARNING: No mapping found for HTTP request with URI [/CONTEXTROOT/] in DispatcherServlet with name 'spring'

Answer 1

Add this to your web.xml

<listener>
    <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
</listener>

also, what's your request looks like?
