java - 从自定义文件夹中读取 MSExchange 电子邮件

Question

有没有办法使用 Java 从 MS-Exchange 中的自定义文件夹中读取电子邮件？我可以从收件箱中读取内容，但我有自定义文件夹名称，电子邮件将移至其中，我希望在这些文件夹中读取代码。

下面是我当前从收件箱读取的代码:

ExchangeCredentials credentials = new WebCredentials("userName", "passWORD", "domain");
service.setCredentials(credentials);
service.setUrl(new URI("https://outlook.mycompany.com/ews/exchange.asmx"));

ItemView view = new ItemView(200);

FindItemsResults<Item> findResults = service.findItems(WellKnownFolderName.Inbox , view);

相反，我想要这样的东西:

FindItemsResults<Item> findResults = service.findItems("My Custom Folder" , view);

我已经尝试过这个，但没有成功:

FindItemsResults<Item> findResults = service.findItems(FolderId.getFolderIdFromString("My Custom Folder") , view);

您需要使用 FindFolder 操作来查找相关文件夹的 ewsId。通常，执行此操作的简单方法是将要访问的文件夹转换为路径，例如，如果该文件夹是收件箱的子文件夹，则路径字符串将是\Inbox\Subfolder 名称，那么您应该能够使用类似以下内容要拆分路径，请执行多个查找以获取您之后的特定文件夹(这是 C#，但您应该能够轻松转换为 java，因为类大部分相同)

    internal static Folder GetFolderFromPath(ExchangeService service,String MailboxName,String FolderPath)
    {
        FolderId folderid = new  FolderId(WellKnownFolderName.MsgFolderRoot,MailboxName);   
        Folder tfTargetFolder = Folder.Bind(service,folderid);
        PropertySet psPropset = new PropertySet(BasePropertySet.FirstClassProperties);
        String[] fldArray = FolderPath.Split('\\'); 
        for (Int32 lint = 1; lint < fldArray.Length; lint++) { 
            FolderView fvFolderView = new FolderView(1);
            fvFolderView.PropertySet = psPropset;
            SearchFilter  SfSearchFilter = new SearchFilter.IsEqualTo(FolderSchema.DisplayName,fldArray[lint]); 
            FindFoldersResults findFolderResults = service.FindFolders(tfTargetFolder.Id,SfSearchFilter,fvFolderView); 
            if (findFolderResults.TotalCount > 0){ 
            foreach(Folder folder in findFolderResults.Folders){ 
                tfTargetFolder = folder;                
                } 
            } 
            else{ 
                tfTargetFolder = null;  
                break;  
            }     
        }
        if (tfTargetFolder != null)
        {
            return tfTargetFolder;
        }
        else
        {
            throw new Exception("Folder Not found");
        }
    }
