I tried following code to upload the file in document directory but no success please help .

ThemeDisplay themeDisplay = (ThemeDisplay) actionRequest.getAttribute(WebKeys.THEME_DISPLAY); String title = file.getName(); DLFolder dlFolder = DLFolderLocalServiceUtil.getFolder(themeDisplay.getScopeGroupId(), 0, "Test"); ServiceContext serviceContext = ServiceContextFactory.getInstance(DLFileEntry.class.getName(),actionRequest); Map<String, Fields> fieldsMap = new HashMap<String, Fields>(); long fileEntryTypeId = DLFileEntryTypeConstants.FILE_ENTRY_TYPE_ID_BASIC_DOCUMENT; FileInputStream inputStream = new FileInputStream(file); DLFileEntry dlFileEntry = DLFileEntryLocalServiceUtil.addFileEntry(themeDisplay.getUserId(), 10153, dlFolder.getRepositoryId(), dlFolder.getRepositoryId(), title, file.getContentType(), title, "fileDesc", "sss", fileEntryTypeId, fieldsMap, file, inputStream, file.length(), serviceContext); inputStream.close(); DLFileEntryLocalServiceUtil.updateFileEntry(themeDisplay.getUserId(), dlFileEntry.getFileEntryId(), title, file.getContentType(), title, "fileDesc", "comment", true, dlFileEntry.getFileEntryTypeId(), fieldsMap, file, null, file.length(), serviceContext);

推荐答案

试试这个代码片段

ThemeDisplay themeDisplay = (ThemeDisplay) actionRequest.getAttribute(WebKeys.THEME_DISPLAY); ServiceContext serviceContext = ServiceContextFactory.getInstance(actionRequest); File file = uploadRequest.getFile("file"); String contentType = MimeTypesUtil.getContentType(file); InputStream inputStream = new FileInputStream(file); Folder folderName = DLAppLocalServiceUtil.getFolder(parentRepositoryId, parentFolderId, "Folder Name"); long folderId = folderName.getFolderId(); long repositoryId = folderName.getRepositoryId(); FileEntry fileEntry = DLAppLocalServiceUtil.addFileEntry(themeDisplay.getUserId(), repositoryId, folderId, file.getName(), contentType, "File Name", "description", "changeLog", inputStream, file.length(), serviceContext);
