Controller My controller inside the com.example.CrudOperations.Controllers and also included in @ComponentScan in main application

 package com.example.CrudOperations.Controllers;

    import org.springframework.web.servlet.ModelAndView;


    @Controller
    public class homeController {

        @RequestMapping("/home")
        public ModelAndView register() {
            ModelAndView mv = new ModelAndView("register");

            return mv;
        }

MainApplication CrudOperations.java here i have included componentscan annotation for scanning the controllers in controller package

package com.example.CrudOperations;

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

import com.example.CrudOperations.Controllers.homeController;


    @SpringBootApplication
    @ComponentScan(basePackages= {"com.example.CrudOperations.Controllers"})
    public class CrudOperationsApplication {

        public static void main(String[] args) {
            SpringApplication.run(CrudOperationsApplication.class, args);
            System.out.println("User Applications Started Running ");
        }

    }
