将零件保存到目录中

Question

I've googled around enough but I can't find the right solution to my issue.

I'm using javamail to download all the attachments of an email and now I do have the attachments but I would like to store them all in a directory. So my code does create a directory (using file.mkdir()) but I haven't been able to move those attachments into my folder (Attachments). This is what I am using so far:

MimeBodyPart part = (MimeBodyPart) multiPart.getBodyPart(i);
    if (Part.ATTACHMENT.equalsIgnoreCase(part.getDisposition())) {
        part.saveFile("/Attachments/" + part.getFileName());
    }

Is there a way to save the part into a folder?

Answer 1

打开FileOutputStream并写出字节。

Answer 2

You don't say exactly what happens when you try to save the attachment. Do you get an exception? Is the attachment stored in the wrong file? I'm sure you understand that what you wrote tries to save it in the /Attachments directory in the root of your filesystem.

Note also that the filename that comes with a part can be complete garbage. Consider what should happen if the filename in the part is "../etc/passwd".

Answer 3

我得到了要保存的文件位置的绝对路径，然后从apache使用FileUtils将文件移动到目录，然后将目录移动到另一个目录。
