업로드

절대 경로에서 파일을 읽어드리는 것

@Test
public void uploadTest() {
    File file = new File("C:\\downloads\\test.txt");
    FileReader fileReader = new FileReader(file);
    BufferedReader bufReader = new BufferedReader(filereader);
    String readLine = null;
    try {
        while((readLine = bufReader.readLine()) != null) {
            System.out.println(line);
        }
        if ( fileReader != null ) {
        	fileReader.close();
        }
        if ( bufReader != null ) {
            bufReader.close();
        }
    }
}

업로드를 통해 일회성으로 읽어드리는 것

@Controller
public class TestController {
    public uploadTest(MultipartHttpServletRequest mRequest){
	TestClass testClass = new TestClass();
	testClass.testMethod(mRequest.getFile("[input type="file의 id]"));
    }
}


public calss TestClass{
    public void testMethod(MultipartFile multipartFile) {
	BufferedReader bufReader = null;
    	String readLine = null;
        try {
            bufReader = new BufferedReader(new InputStreamReader(multipartFile.getInputStream()));
            while ( readLine = bufReader.readLine() != null ) {
            	System.out.println( readLine );
            }
            if ( bufReader != null ) {
                bufReader.close();
            }
        } 
    }
}
