我需要使用Java程序获取服务器的hostId。

I need to get the hostId of my server using a Java program. Is there something in the Java API that is built-in which can help me do this?

lab.com$ hostid
f9y7777j -> How can I get this using java

推荐答案

您可以运行控制台命令并存储结果：-

The following would allow you to run a console command and store the result:-

 ProcessBuilder pb = new ProcessBuilder("hostid");
 Process p = pb.start();
 BufferedReader reader = new BufferedReader(new InputStreamReader(p.getInputStream()));
 String line = null;
 while ((line = reader.readLine()) != null)
 {
    // Store returned string here.
 }
 reader.close();
