Error when deploying spring boot

I am new to spring boot, create a basic example with no connection to BD, I only have the dependency spring-boot-starter-web and spring-boot-starter

My main class:

package com.sinbugs.contacts;

import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.EnableAutoConfiguration;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RestController;

@EnableAutoConfiguration
@RestController
public class EasyNotes1Application {
    @RequestMapping("/")
    String home() {
        return "Hola por fa";
    }

    public static void main(String[] args) {
        SpringApplication.run(EasyNotes1Application.class, args);
    }
}
