Question

我正在运行这样的流程：

builder = new ProcessBuilder("/bin/bash", "-c", "./MessageGenerator | ./SimpleEchoServer");
process = builder.start();

然后process.destroy（）或forciblyDestroy（）不起作用。是因为我正在使用烟斗吗？我怎样才能杀死这些进程？

你还应该拆分管道命令。我写了一个小例子：

package com.company;

import java.io.*;

public class Main {

    public static void main(String[] args) throws IOException, InterruptedException {
        ProcessBuilder processBuilder;
        String line;
        processBuilder = new ProcessBuilder("/bin/bash", "-c", "ls -l", "|", "grep java");
        Process process = processBuilder.start();
        BufferedReader reader = new BufferedReader(new InputStreamReader(process.getInputStream()));
        while ((line = reader.readLine()) != null) {
            System.out.println ("Stdout: " + line);
        }
        Thread.sleep(10000);
        process.destroy();
    }
}

Java Kill进程以ProcessBuilder开始
