java mail imap 保存附件问题

[rain9355]

	private static void saveFile(InputStream in, String destDir, String fileName)
			throws Exception {
		String osName = System.getProperty("os.name");
		String storedir = destDir;
		String separator = "";
		if (osName == null)
			osName = "";
		if (osName.toLowerCase().indexOf("win") != -1) {
			separator = "/";
			if (storedir == null || storedir.equals(""))
				storedir = "c:/tmp";
		} else {
			separator = "/";
			storedir = "/tmp";

		}
		File storefile = new File(storedir + separator + fileName);
		System.out.println("storefile's　path:　" + storefile.toString());

		BufferedOutputStream bos = null;
		BufferedInputStream bis = null;
		try {
			bos = new BufferedOutputStream(new FileOutputStream(storefile));
			bis = new BufferedInputStream(in);
			int c;
			while ((c = bis.read()) != -1) {
				bos.write(c);
				bos.flush();
			}
		} catch (Exception exception) {
			exception.printStackTrace();
			throw new Exception("文件保存失败!");
		} finally {
			bos.close();
			bis.close();
		}
	}

在保存附件的时候老是报错，

在解密的时候

我这个是接收的，发送的是序列化后的文件和压缩文件。发送是没有问题的

使用pop3接收的话附件是可以正常接收保存的

好像imap在接收邮件的时候InputStream是空的，不知道怎么解决

楼主 你是使用imap 接收和发送文件的？
