java - 从 java 运行 .exe 并继续

Question

如果 .exe 程序尚未运行，我想以编程方式运行它。目前，我使用进程生成器从 java 启动 .bat。批处理文件在检查 .exe 是否正在运行后运行它。问题是，在用户关闭 .exe 程序之前，java 不会继续运行。我该如何解决这个问题？

Java 代码:

try {
        ProcessBuilder builder = new ProcessBuilder("open.bat");
        final Process process = builder.start();
        InputStream is = process.getInputStream();
        InputStreamReader isr = new InputStreamReader(is);
        BufferedReader br = new BufferedReader(isr);
        while ((br.readLine()) != null) {
        }
        System.out.println("command line terminated");
    } catch (Exception err) {
        err.printStackTrace();
        System.out.println("error  ");
    }

批处理代码:(open.bat)

tasklist | find "illustrator.exe"
if errorlevel 1 start "" "C:\Program Files (x86)\Adobe\Adobe Illustrator CS6\Support Files\Contents\Windows\illustrator.exe"

使用...

start "" "C:\Program Files (x86)\Adobe\Adobe Illustrator CS4\Support Files\Contents\Windows\illustrator.exe"

作为open.bat批处理文件并使用...

try {
    ProcessBuilder builder = new ProcessBuilder("open.bat");
    builder.redirectError();
    builder.inheritIO();
    final Process process = builder.start();
    final InputStream is = process.getInputStream();
    InputStreamReader isr = new InputStreamReader(is);
    BufferedReader br = new BufferedReader(isr);
    String text = null;
    while ((text = br.readLine()) != null) {
        System.out.println(text);
    }

    System.out.println("command line terminated");
    System.out.println("Exited with " + process.waitFor());
} catch (Exception err) {
    err.printStackTrace();
    System.out.println("error  ");
}

我可以让批处理文件运行并终止，并且仍然可以加载和运行 Illustrator。

主要的添加是对 ProcessBuilder#inheritIO 的调用，它做了一些我不知道的魔法，但似乎允许批处理文件终止......

This gives behavior equivalent to most operating system command interpreters, or the standard C library function system().
