使用API将文件保存到Liferay 6.1中的Document目录
问题描述：
我需要将上传的文件保存在Document&的子目录中.来自Web表单portlet的liferay中的媒体文件夹.
我已经扩展了Web Form Portlet的功能，但是文件已成功上传到数据库&中.不在Document&媒体文件夹.
我尝试了以下代码将文件上传到文档目录中，但没有成功，请帮助.
I need to save a uploaded file in sub directory of Document & Media folder in liferay from web-form portlet.
I have extended the web Form portlet to do so, but file is getting uploaded successfully in database & not in Document & Media folder.
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);
答
尝试此代码段
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);
