如何使用不同的线程读取每个日志文件

Question

基本上，我连接到远程服务器并从日志文件夹中获取所有日志文件名。我在列表中添加了这些文件名，现在我想在该文件上读取或尾部-f，我应该寻找是否有任何文件遇到＆＃34;错误＆＃34;然后我应该能够写出其他文件了。 我想使用多线程，我想创建线程来单独读取每个日志文件。

例如：

public List<String> excuteScript(String fileName) {
    List<String> result = new ArrayList<String>();
    try {
        JSch jSch = new JSch();
        Session session = jSch.getSession(USERNAME, host, port);
        session.setConfig("StrictHostKeyChecking", "no");
        session.setPassword(PASSWORD);
        session.connect();
        //create the excution channel over the session
        ChannelExec channelExec = (ChannelExec)session.openChannel("exec");

        // Gets an InputStream for this channel. All data arriving in as messages from the remote side can be read from this stream.
        InputStream in = channelExec.getInputStream();

        // Set the command that you want to execute
        // In our case its the remote shell script
        channelExec.setCommand("sh " + fileName);

        // Execute the command
        channelExec.connect();
        System.out.println("connected");

        // Read the output from the input stream we set above
        BufferedReader reader = new BufferedReader(new InputStreamReader(in));
        String line;

        //Read each line from the buffered reader and add it to result list
        // You can also simple print the result here 
        while ((line = reader.readLine()) != null) {
            if(line.contains("Error") || line.contains("Exception")) {
                System.out.println(line);
                result.add(line);
            }
        }
        //retrieve the exit status of the remote command corresponding to this channel
        int exitStatus = channelExec.getExitStatus();

        //Safely disconnect channel and disconnect session. If not done then it may cause resource leak
        channelExec.disconnect();
        session.disconnect();

        if(exitStatus < 0) {
            // System.out.println("Done, but exit status not set!");
        }
        else if(exitStatus > 0) {
            // System.out.println("Done, but with error!");
        }
        else {
            // System.out.println("Done!");
        }
    } 
    catch(Exception e) {
        System.err.println("Error: " + e);
    }
    return result;
}
