[질문 내용]
안녕하세요 선생님

학원에서는 이클립스 위주로 하여 인텔리제이 사용이 미숙합니다. 메인메소드를 run하니 8080포트를 이미 쓰고 있다고 하고, localhost:8080에 접속하면 팝업창으로 로그인창이 뜹니다.

어떻게 해결해야할까요?

java 버전 : 17.
spring initialize 버전 : 3.1.2.

[메인메소드가 있는 클래스]

package yn.ynspring;

import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;

@SpringBootApplication
public class YnSpringApplication {

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

}
