java - Exchange Web 服务搜索自定义文件夹名称

Question

我需要找到名为“Archived”的文件夹，该文件夹位于父级别，而不是子文件夹。如果“Archived”文件夹是子文件夹，我不希望它返回到结果集中。这是我编码的内容，但这也会返回子文件夹。

HashMap<String, FolderId> folderIdList = new HashMap<String, FolderId>();

FolderId readFromId = null; // Folder to read emails from - Inbox
FolderId moveToId = null;   // Folder to move emails to after processing - Archived

FolderView view = new FolderView(Integer.MAX_VALUE);

view.setPropertySet(new PropertySet(BasePropertySet.IdOnly));
view.getPropertySet().add(FolderSchema.DisplayName);
view.setTraversal(FolderTraversal.Deep);

try {
    FindFoldersResults findFolderResults = service.findFolders(
        new FolderId(WellKnownFolderName.MsgFolderRoot, userMailbox), view);

    // find specific folder
    for (Folder folder : findFolderResults) {
        System.out.println(folder.getDisplayName());

        // look for the desired folder name
        if (folder.getDisplayName().equalsIgnoreCase("Inbox")) {
            // get the id
            readFromId = folder.getId();
        }
            // add the folder id to map
            folderIdList.put(UtilConstants.READ_FROM, folder.getId());

        } else if (folder.getDisplayName().equalsIgnoreCase("Archived")) {
            // get the id
            moveToId = folder.getId();
        } else {
            // add the folder id to map
            folderIdList.put(UtilConstants.MOVE_TO, folder.getId());
        }
    }
} catch (Exception e) {
    log.error("Error while getting the folder id's for folders " +
        readFrom + ", " + moveTo + "" + e.getMessage());
    throw e;
}

return folderIdList;

I need to find the folder name "Archived" which will be at the Parent level

如果是这种情况，您不应该使用深度遍历，因为这将返回层次结构中的所有文件夹，而不仅仅是顶层的文件夹。我还建议您使用 SearchFilter 这样它只返回您想要的文件夹，这将简化您的代码，例如:

String folderSearchName = "Archived";

FolderView fvFolderView = new FolderView(1);
fvFolderView.Traversal = FolderTraversal.Shallow;

SearchFilter fsFolderSearch = new SearchFilter.IsEqualTo(FolderSchema.DisplayName, folderSearchName);

FolderId SearchRoot = new FolderId(WellKnownFolderName.MsgFolderRoot, "user@domain.com");

FindFoldersResults folderSearchResults = service.FindFolders(SearchRoot, fsFolderSearch, fvFolderView);
if (folderSearchResults.Folders.Count == 1) 
{
    Console.WriteLine(folderSearchResults.Folders[0].DisplayName);
}
