글쓰기부분을 입력하면 콘솔창에 출력되는걸 확인할 수 있다.

resource디렉토리안에 upload폴더 추가

폴더추가한걸 properties에 경로를 입력해준다.

option.properties

path.upload = //Users//jeongsujin//springProject//.metadata//.plugins//org.eclipse.wst.server.core//tmp0/wtpwebapps//MiniProject//resources//upload

page.listcnt = 10
page.paginationcnt = 10

BoardService.java

@Service
@PropertySource("/WEB-INF/properties/option.properties") //경로설정
public class BoardService {
	
	@Value("${path.upload}")
	private String path_upload;
	
	//서버로 업로드 된 파일을 업로드 폴더에 저장하고 파일의 이름을 리턴하는 메서드 
	private String saveUploadFile(MultipartFile upload_file) {
		//현재시간(밀리세컨드)을 이용해서 파일의 이름이 중복되지 않게 설정
		String file_name = System.currentTimeMillis() + "_" + upload_file.getOriginalFilename();
	
		try {
			upload_file.transferTo(new File(path_upload + "/" + file_name));
		}catch(Exception e) {
			e.printStackTrace();
		}
		
		return file_name;
	}

	public void addContentInfo(ContentBean writeContentBean) {
		
		MultipartFile upload_file = writeContentBean.getUpload_file();
		
		if(upload_file.getSize() > 0 ) {
			String file_name = saveUploadFile(upload_file);
			writeContentBean.setContent_file(file_name);

//		System.out.println(writeContentBean.getContent_subject());
