如何使用Java获取chromedriver进程PID？

您可以使用pgrep找到PID，然后将其杀死：

    private void killChromedriver() throws IOException, InterruptedException {        String command = "pgrep chromedriver";        Process process = Runtime.getRuntime().exec(command);        BufferedReader br = new BufferedReader(new InputStreamReader(process.getInputStream()));        List<String> processIds = getProcessedIds (process, br);        for (String pid: processIds) {     Process p = Runtime.getRuntime().exec("kill -9 " + pid);     p.waitFor();     p.destroy();        }    }    private List<String> getProcessedIds(Process process, BufferedReader br) throws IOException, InterruptedException {        process.waitFor();        List<String> result = new ArrayList<>();        String processId ;        while (null != (processId = br.readLine())) { result.add(processId);        }        process.destroy();        return result;    }

更新

另一个更简单的解决方案似乎是

    Runtime.getRuntime().exec("pkill chromedriver");
