Consider defining a bean of type 'service' in your configuration [Spring boot]

I get error when I run the main class.

Error:

Action:

Answer 1

I fixed the problem adding this line @ComponentScan(basePackages = {"com.example.DemoApplication"}) to main class file, just up from the class name

package com.example.demo;

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

@SpringBootApplication
@ComponentScan(basePackages = {"com.example.DemoApplication"})
public class DemoApplication {

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

}
