Springboot : startup issue(missing ServletWebServerFactory bean)

I have added the annotation on main class,given below:

package com.main;

import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.EnableAutoConfiguration;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.context.annotation.ComponentScan;
import org.springframework.context.annotation.Configuration;
import org.springframework.web.bind.annotation.CrossOrigin;

import com.controller.RequestClass;

@CrossOrigin(origins = "http://localhost:4200")
@SpringBootApplication
@Configuration
@EnableAutoConfiguration
@ComponentScan("com.*")
public class MainClass
{
    public static void main(String[] args)
    {
        SpringApplication.run(RequestClass.class, args);
    }
}

but on running the application , facing below error.

What happens if springapplicatiom.run is against the main class not the controller class - does it start ? Take a look at this thread https://stackoverflow.com/a/44466367/5126865 (am assuming a bit about what you want to achieve so apologies if off the mark)
