Question

我想上传一个大文件，例如SFTP服务器。我可以成功连接，并且上传较小的文件不是问题。我要上传大于150MB的文件时，上传失败。

我不知道为什么会这样。如果我使用FileZilla之类的东西将同一文件传输到同一服务器，则一切正常。所以我想问题是我的Java实现。

发生这种情况时，我收到“ Inputstream已关闭”的异常：

main()

这是我的代码：

这是我的Jsch日志

public void upload(StorageCredentials credentials, String uploadFileName, String uploadVolumeName, BufferedInputStream bis, String localFilePath, String localFileSize) throws Exception {
    JSch jsch = new JSch();
    Session session = null;
    try {
        session = jsch.getSession(credentials.getAccessKey(), credentials.getEndPointURL(), 22);
        session.setConfig("StrictHostKeyChecking", "no");
        session.setPassword(credentials.getSecretKey());
        session.connect();

        Channel channel = session.openChannel("sftp");
        channel.connect();
        ChannelSftp sftpChannel = (ChannelSftp) channel;
        sftpChannel.put(localFilePath, "/" + PATH + uploadFileName);
        sftpChannel.exit();
        session.disconnect();
    }
    catch (JSchException e) {
        e.printStackTrace();
    }
    catch (SftpException e) {
        e.printStackTrace();
    }
}

Session的默认超时应为“ 0”（无限），但是有时OS会覆盖它。

尝试通过setTimeout()手动设置超时；

public void upload(StorageCredentials credentials, String uploadFileName, String uploadVolumeName, BufferedInputStream bis, String localFilePath, String localFileSize) throws Exception {
    JSch jsch = new JSch();
    Session session = null;
    try {
        session = jsch.getSession(credentials.getAccessKey(), credentials.getEndPointURL(), 22);
        session.setConfig("StrictHostKeyChecking", "no");
        session.setPassword(credentials.getSecretKey());
        session.connect(300000); // 5 mins

        Channel channel = session.openChannel("sftp");
        channel.connect();
        ChannelSftp sftpChannel = (ChannelSftp) channel;
        sftpChannel.put(localFilePath, "/" + PATH + uploadFileName);
        sftpChannel.exit();
        session.disconnect();
    }
    catch (JSchException e) {
        e.printStackTrace();
    }
    catch (SftpException e) {
        e.printStackTrace();
    }
}

Jsch文件上传被取消
