| multipart form parser - http file upload, database 저장 java class 연재2 이번글에서는 업로드된 파일을 저장할때 database에 record를 함께 insert 하는 기능에 대해서 설명하겠습니다. 설명하기 전에 이전 글에서 대용량 파일 업로드 기능에 대해서 다시 한번 review하고 다시 자세히 설명하겠습니다. 1. 대용량 파일 업로드 기능 (1G 이상 파일 업로드에도 문제가 없는 기능) 2. 파일 업로드시 upload 진행 상황을 Internet Explorer에서 볼수 있을것 (다음번 글에서 올리겠습니다.) WCPage.java : JSP page context와 request parameter를 저장하는 java class WCMultipartFormParser.java : http request stream을 parsing하는 java class WCMultipartFormElement.java : multipart form lement를 저장하는 java class // form html 일부분 시작 <form name="fParam" encType="multipart/form-data"> <input type="hidden" name="_cmd" value="file_data"> <input type="file" name="file"> </form> // form html 일부분 끝 form을 javascript에서 서버로 submit하면 아래와 같은 http request stream이 서버로 전달됩니다. // http request stream 시작 -----------------------------7d82efc203cc Content-Disposition: form-data; name="_cmd" uploadFile -----------------------------7d82efc203cc Content-Disposition: form-data; name="file"; filename="C:\test.txt" Content-Type: text/plain test -----------------------------7d82efc203cc-- // http request stream 끝 위의 request stream을 parsing하는 pseudo code 입니다. // pseudo code 시작 JSP page -> WCPage.initCtrl -> WCPage.initCtrl -> WCPage.isMultipart() -> WCMultipartFormParser.init() -> WCMultipartFormParserparseContent(oRequest) -> WCMultipartFormParserparseContentEx(oRequest) -> WCMultipartFormParserfindBoundary() : -----------------------------7d82efc203cc 이 부분을 parsing합니다. -> WCMultipartFormParserfindHeader() : Content-Disposition: form-data; name="_cmd" 이 부분을 parsing 합니다. -> WCMultipartFormElement.setHeader : header 정보를 element에 저장합니다. -> WCMultipartFormParser.procContent() : content body를 parsing 합니다. -> 임시파일에 파일 저장 : content type이 file인경우 -> parameter인경우 WCProperties m_rParam 에 parameter 이름과 value를 저장 -> WCMultipartFormParser.saveFile(sDir) -> WCMultipartFormElement.saveFile(sPathFile) // pseudo code 끝 대용량 파일을 서버에 업로드 하기 위해서는 업로드 되는 파일을 임시 directory에 임시 파일로 저장을 하고 다시 개발자가 원하는 디렉토리로 파일을 이동하는 방식을 사용합니다. (임시로 저장하는 이유는 memory에 파일을 모두 load하고 있을 수 없기 때문입니다.) 위의 코드에서 procContent에서 파일 내용을 임시 디렉토리에 저장합니다. WCMultipartFormParser.procContent 사용자가 파일을 임시 디렉토리에서 운영용 file directory로 이동하고자 하면 WCMultipartFormParser.saveFile(sDir) 을 호출합니다. 이 함수를 form에 있는 element들 중에서 file인 경우 이 파일을 사용자가 지정한 sDir로 이동을 합니다. // WCMultipartFormParser.saveFile code 시작 public void saveFile(String sDir) { try { Vector vElement = this.getElements(); int nCount = WCVector.size(vElement); for (int i=0;i<nCount;i++) { WCMultipartFormElement oElmt = (WCMultipartFormElement)WCVector.getObjAt(vElement,i); if (oElmt == null) { continue; } if (!oElmt.isFile()) { continue; } String sTempFileName = oElmt.getCloneFileName(); if (WCString.isEmpty(sTempFileName)) { continue; } String sUserDirectoryFile = WCString.buildFilePath(sDir,sTempFileName,"/"); oElmt.saveFile(sUserDirectoryFile); } } catch (Exception ex) { WCLog.getInstance().printLog("exception at WCMultipartFormParser.saveFile "+ex.toString()); } } // WCMultipartFormParser.saveFile code 끝 WCMultipartFormParser.saveFile 에서 WCMultipartFormElement.saveFile을 호출합니다. WCMultipartFormElement.saveFile 함수는 임시로 저장된 file을 사용자가 지정한 path의 file로 copy한 다음 임시 파일을 삭제하는 코드입니다. // WCMultipartFormElement.saveFile code 시작 public int saveFile(String sPathFile) { try { if (sPathFile == null) return -1; String sDir = WCString.getPath(sPathFile); WCSystem oSys = WCSystem.getInstance(); oSys.CreateDir(sDir); String sSaveFileName = sPathFile; setSaveFileName(sSaveFileName); File oSrcFile = new File(getTempFileName());
