通过UAC提升ProcessBuilder流程？

我正在尝试运行一个外部可执行文件，但显然它需要提升。代码是从使用ProcessBuilder的示例（因此带有一个参数的数组）的示例修改而来的：

    public static void main(String[] args) throws IOException {        File demo = new File("C:\\xyzwsdemo");        if(!demo.exists()) demo.mkdirs();        String[] command = {"C:\\fakepath\\bsdiff4.3-win32\\bspatch.exe"};        ProcessBuilder pb = new ProcessBuilder( command );        Process process = pb.start();        InputStream is = process.getInputStream();        InputStreamReader isr = new InputStreamReader(is);        BufferedReader br = new BufferedReader(isr);        String line;        System.out.printf("Output of running %s is:\n", Arrays.toString(command));        while ((line = br.readLine()) != null) {            System.out.println(line);        }        try {            int exitValue = process.waitFor();            System.out.println("\n\nExit Value is " + exitValue);        } catch (InterruptedException e) {            e.printStackTrace();        }    }

运行时返回：

Exception in thread "main" java.io.IOException: Cannot run program "C:\Users\Gilliane\Downloads\bsdiff4.3-win32\bspatch.exe": CreateProcess error=740, The requested operation requires elevation

我已经进行了一些浏览，并且知道在C＃中，您可以通过执行以下操作来请求提升（如从该线程中看到的）：

startInfo.Verb = "runas";

但是，我在ProcessBuilder中看不到任何类似的东西。另一种方法是将Elevation
Tools安装在目标系统上，并使用ProcessBuilder调用“
elevate”提示。但是，我不想强​​迫使用我的程序的人也安装这些提升工具。

还有另一种方法吗？

使用ProcessBuilder无法做到这一点，您需要调用Windows API。

我使用JNA通过类似于以下代码的代码来实现此目的：

Shell32X.java：

Elevator.java：
