[Spring] 로그가 안찍히는 에러

스프링 프로젝트를 세팅하고 서버 실행해서 확인해보는데 로그가 찍히지 않아서 이유를 열심히 찾아보았다

 

코드

import lombok.extern.slf4j.Slf4j;

@Slf4j
@Controller
@RequestMapping("testtt")
public class TestController {
	
	@GetMapping("name")
	public String name() {
    
		log.debug("로그로그");
        
		return "dd";
	}
}

 

에러

해결

log4j 버전도 바꿔보고 lombok도 다시 설치하고 다 해봤지만 이유는 간단했다

워크스페이스가 사용자이름 하위에 있어서 경로에 한글이 포함된 것이었다

c드라이브 바로 밑으로 옮겨주었더니 문제가 해결되었다

 

로그가 나오지 않는 다양한 이유가 있겠지만 에러메시지에 이상하게 한글이 한개 보인다면 이 방법을 사용해보자!
