java 执行 exe 文件

 https://blog.csdn.net/u013256816/article/details/54603910

主要点:

1. Runtime.getRuntime().exec(cmd); 这个方法最终调用的是 ProcessBuilder 的方法执行的命令, 所以 ProcessBuilder 比 Process 提供了更多的方法用于对进程的控制

2. cmd 命令执行 .exe 如何传递参数

3. 执行.exe 文件, 但是cmd 窗口隐藏,不显示

4. 如何监听cmd命令执行 .exe 文件结束

封装java调用命令行, 多命令

    public static List<String> executeNewFlow(List<String> commands) {
        List<String> rspList = new ArrayList<String>();
        Runtime run = Runtime.getRuntime();
        try {
            Process proc = run.exec("/bin/bash", null, null);
            BufferedReader in = new BufferedReader(new InputStreamReader(proc.getInputStream()));
            PrintWriter out = new PrintWriter(new BufferedWriter(new OutputStreamWriter(proc.getOutputStream())), true);
            for (String line : commands) {
                out.println(line);
            }
            out.println("exit");// 这个命令必须执行，否则in流不结束。
            String rspLine = "";
            while ((rspLine = in.readLine()) != null) {
                System.out.println(rspLine);
                rspList.add(rspLine);
            }
            proc.waitFor();
            in.close();
            out.close();
            proc.destroy();
        } catch (IOException e1) {
            e1.printStackTrace();
        } catch (InterruptedException e) {
            e.printStackTrace();
        }
        return rspList;
    }
