Question

我正在尝试使用元数据上传文档。简单文件上传器portlet工作正常，但当我尝试附加元数据时，它发送请求失败错误

这是我的代码

public DLFileEntry upload(ActionRequest request, ActionResponse response)  throws Exception 
{
    // TODO Auto-generated method stub
    ServiceContext sc = new ServiceContext();
    Date date1 = (Date) request.getAttribute("efrom");
    Date date2 = (Date) request.getAttribute("efrom");
    String getTitle = request.getParameter("Title");
    String getDesc = request.getParameter("Description");
    String CKEditor = request.getParameter("CKE");

    ThemeDisplay themeDisplay = (ThemeDisplay) request.getAttribute(WebKeys.THEME_DISPLAY);
    long defaultRepoId = DLFolderConstants.getDataRepositoryId(themeDisplay.getScopeGroupId(), DLFolderConstants.DEFAULT_PARENT_FOLDER_ID);

    String rtfoutput = FileIO.readFromFile(tPath);

    File tempFile = new File(tPath);
    InputStream is = new FileInputStream(tempFile);

    Folder folderName = DLAppLocalServiceUtil.getFolder(defaultRepoId, 0, "Folder Name");
    long folderId = folderName.getFolderId();
    long repositoryId = folderName.getRepositoryId();

    byte[] bytes = rtfoutput.getBytes();

    Map<String, Fields > fieldsMap = new HashMap<String, Fields >();
    Fields targetFields = new Fields();
    targetFields.put(new Field("Effective-To", date1));
    targetFields.put(new Field("Effective-From", date2));

    fieldsMap.put("", targetFields);

    DLFileEntry dlFileEntry = DLFileEntryLocalServiceUtil.addFileEntry(defaultRepoId, 0L, repositoryId, folderId, getTitle+".rtf", "RichTextFormat", getTitle, StringPool.BLANK, StringPool.BLANK, 0L,
            fieldsMap, tempFile, is, tempFile.getTotalSpace(), sc);

    return dlFileEntry;
}

我不明白为什么这说请求失败

date1和date2是我试图通过文档获取的元细节

我认为你不能简单地添加自定义元数据。每个FileEntryType都有一个可能的DDMStructure描述的metada字段集合。但是，您应首先创建/更新FileType的DDMS结构，然后再放置新的MetaData。有关详细信息，请参阅liferay的源代码和这篇文章：http://www.liferay.com/de/community/forums/-/message_boards/message/13460906

在liferay中上传包含元数据的文档
