6. Application.java

 

package com.sample;

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

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

 

7. 실행 ( Shift + F10 )

 

 

8. 실행결과 ( 일단 시작은 됐음. )

 

 

9. 브라우저 실행

 

※ Web server failed to start. Port 8080 was already in use.

 

※ IntelliJ는 뭔가 옵션이 보여짐. ㅎㅎ
