my Controller HelloController.java
package com.tutorialspoint.controller;
import org.springframework.stereotype.Controller;
import org.springframework.ui.ModelMap;

import org.springframework.web.bind.annotation.RequestMethod;
@Controller
public class HelloController {
@RequestMapping(value = "/hello", method = RequestMethod.GET)
public String printHello(ModelMap model) {
model.addAttribute("message", "Hello Spring MVC Framework!");
return "hello";
}
}
hello.jsp
<%@ page contentType="text/html; charset=UTF-8" %>
<html>
<head>
<title>Hello World</title>
</head>
<body>
<h2>${message}</h2>
</body>
</html>
Can anyone please suggest me what is wrong in code?

I believe that you are following the tutorial of tutorialspoint - HelloWorld for Spring MVC. I have the same issue which happens because DispatcherServlet try to resolve.
http://localhost:8080/HelloWeb/
It should be:
http://localhost:8080/HelloWeb/hello
(Put this in your web-browser)
Or it can be done another way (as suggested in that tutorial)
You should note that in the given URL, HelloWeb is the application name and hello is the virtual subfolder which we have mentioned in our controller using @RequestMapping("/hello"). You can use direct root while mapping your URL using @RequestMapping("/"), in this case you can access the same page using short URL
http://localhost:8080/HelloWeb/but it is advised to have different functionalities under different folders.
in HelloWorldController class, you change this:
@RequestMapping("/hello")
to this:
@RequestMapping("/")
the result is that you can call http://localhost:8080/HelloWeb/ without any problem.
Hope it helps!
