是否可以从远程服务器连续获取文件内容 [英] Is that possible to get file content continuously from remote server

问题描述

我知道在本地可以逐行获取文件内容.就像

I know locally it is possible to get file content line by line. just like

Scanner s = new Scanner(new File("D:\\Users\\qding\\Desktop\\spy.log"));
    while (s.hasNextLine()) {
        String line = s.nextLine();
        System.out.println("[Method Server] " + line);
}

是否可以从远程(Windows/Linux)获取文件内容?

Is it possible to get file content from remote (Windows/Linux)?

此外，在远程文件中，该文件是一个日志文件，并且始终会更新.所以第二个问题是是否可以连续归档内容(多线程?)?

Also, on the remote, the file was a log file, and it is updated always. So the second question is if is possible to file content continuously (with multiple thread?)?
