用Java Ping多台服务器

用Java Ping多台服务器

如果没有

ProcessBuilder

别人的建议，怎么办呢？

我有三个类-

PingParallel

是我的主类，

PingTask

是每个线程执行的任务，并且

PingResult

有结果代码（我们还可以添加一些其他信息，状态消息等）。

平平行

package com.test.thread;import java.util.ArrayList;import java.util.Date;import java.util.List;import java.util.concurrent.Callable;import java.util.concurrent.ExecutorService;import java.util.concurrent.Executors;import java.util.concurrent.Future;public class PingParallel {    public static void main(String[] args) {        int totalIps = 89;        ExecutorService executor = Executors.newFixedThreadPool(totalIps);        List<Future<PingResult>> list = new ArrayList<Future<PingResult>>();        Callable<PingResult> callable = null;        for(int i=0; i< totalIps; i++){ callable = new PingTask("127.0.0"+i); // Get the ipAddres buttons[i].getText()); Future<PingResult> future = executor.submit(callable); list.add(future);        }        for(Future<PingResult> fut : list){ try {     System.out.println(new Date()+ "::"+fut.get()); } catch (Exception e) {     e.printStackTrace(); }        }        executor.shutdown();    }}

PingTask

package com.test.thread;import java.net.InetAddress;import java.util.concurrent.Callable;public class PingTask implements Callable<PingResult> {  private String ipAddress;  public PingTask(String ipAddress) {    this.ipAddress = ipAddress;  }  @Override  public PingResult call() {    InetAddress inet = null;    try {      inet = InetAddress.getByName(ipAddress);      int resultCode = inet.isReachable(5000) ? 0 : -1;      return new PingResult(ipAddress, resultCode);    } catch (Exception e) {      e.printStackTrace();      return new PingResult(ipAddress, -1);    }  }}

PingResult

package com.test.thread;public class PingResult {  private String ipAddress;  private int resultCode;  public PingResult(String ipAddress, int resultCode) {    this.ipAddress = ipAddress;    this.resultCode = resultCode;  }  public String getIpAddress() {    return ipAddress;  }  public int getResultCode() {    return resultCode;  }  public String toString() {    return "IpAddress :: "+ ipAddress + " Result Code : "+ resultCode;  }}
