通过java processBuilder运行cmd命令

Question

我正在尝试使用ProcessBuild运行cmd语句。

ProcessBuilder pb = new ProcessBuilder("cmd.exe", "/C", "start");
Process p = pb.start();

但是，我只能打开cmd。exe

那么如何编写此语句通过java运行cmd命令？？我得到了错误，因为语句由"*"组成。如何编辑ProcessBuilder以便我可以运行语句？非常感谢

您可以设置要执行命令的目录

    List<String> cmds = Arrays.asList("cmd.exe", "/C", "start", "java", "-mx4g", "-cp", "*", "edu.stanford.nlp.pipeline.StanfordCoreNLPServer");
    ProcessBuilder builder = new ProcessBuilder(cmds);
    builder.directory(new File("D:/stanford-corenlp-full-2015-12-09"));
    Process proc = builder.start();

根据评论中的要求进行更新

    OutputStream out = proc.getOutputStream();
    new Thread(() -> {
        try (BufferedWriter bw = new BufferedWriter(new OutputStreamWriter(out))) {
            bw.write("[command here]");
            bw.flush();
        } catch (IOException ioe) {
            ioe.printStackTrace();
        }

    }).start();
