When I am putting the jsp files outside the views folder under webapp it works well
but When I cut and paste them inside views folder first jsp page (practice1.jsp displays but when I click the submit button following errors comes:


Whitelabel Error Page
This application has no explicit mapping for /error, so you are seeing this as a fallback.

There was an unexpected error (type=Not Found, status=404).

What I have tried:

/practice2/src/main/java/com/example/demo/Practice1Application.java
package com.example.demo;

import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.context.annotation.ComponentScan;

@SpringBootApplication

@ComponentScan("com.*")
public class Practice1Application {

	public static void main(String[] args) {
		SpringApplication.run(Practice1Application.class, args);
		System.out.println("Application started");
	}

}

/practice2/src/main/java/com/example/demo/Practice1Controller.java
package com.example.demo;

import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RequestParam;
import org.springframework.web.servlet.ModelAndView;


@Controller
public class Practice1Controller {
	
	//@RequestMapping("/practice1Jsp")
	@RequestMapping("/")
	public String practice()
	{
		//System.out.println("practice1 controller");
		return "practice1Jsp.jsp";
	}
	
	@RequestMapping("/add")
	public ModelAndView add(@RequestParam("num1")int n1,@RequestParam("num2")int n2)
	{
	
		ModelAndView mv=new ModelAndView();
		
		mv.setViewName("result.jsp");
		int num3=n1+n2;
		
		
		mv.addObject("num3",num3);
		
		
		return mv;
	}

}
