JavaMail重命名文件夹

 前言:

 最近有点焦虑，还是坚持自己吧，加油！

 和上篇创建文件夹的方法类似 JavaMail创建文件夹 所以，直接切入主题吧。

 查看重命名API

  

public abstract boolean renameTo(Folder newName)
                          throws MessagingException
Rename this folder; the folder must be closed. If the rename is successfull, a FolderEvent.RENAMED event is sent to all listeners registered with this folder or with the store.
Parameters:
newName - the new name for this folder
Returns:
true if the rename succeeded
Throws:
MessagingException - if there was a problem accessing the store

谷歌翻译如下：重命名此文件夹; 文件夹必须关闭。 如果重命名成功，则将向该文件夹或商店注册的所有侦听器发送Folder Event.RENAMED事件。

参数：该文件夹的新名称

意思很明了吧，也比较简单。

代码实现

  public void renameFolder(final String renameFolderName,final String folderName, final createFolderCallBack callBack) throws MessagingException {
        Store store = imapSession.getStore("imaps");
        store.connect(Constant.imapInfo.getServerName(), Constant.imapInfo.getLoginName(), Constant.imapInfo.getPassword());
        Folder folder = store.getDefaultFolder();
        try {
            //根目录的时候不需要open,不是根目录，就要open
            // folder.open(Folder.READ_WRITE);
            Folder myFolder = folder.getFolder(renameFolderName);
            myFolder.addFolderListener(new FolderListener() {
                @Override
                public void folderRenamed(FolderEvent folderEvent) {
                    if(null != callBack){
                        callBack.renamed(folderName);
                    }
                }
                @Override
                public void folderDeleted(FolderEvent folderEvent) {
                    if(null != callBack){
                        callBack.deleted(folderName);
                    }
                }
                @Override
                public void folderCreated(FolderEvent folderEvent) {
                    if(null != callBack){
                        callBack.created(folderName);
                    }
                }
            });
            Folder newFolder = folder.getFolder(folderName);//新建一个文件夹，名字为新的名字，使用myFolder.renameTo实现重命名
            boolean isRenamed = myFolder.renameTo(newFolder);
            System.out.println("MailHelper rename folder " + isRenamed);
        } catch (Exception e) {
            Logger.e("MailHelper.class",e.getMessage());
            if(null != callBack){
                callBack.deleted(folderName);
            }
        }
    }
