java - 如何在 Java 中执行字符串中的代码

Question

我正在尝试开发一个需要远程调试的安全系统。所以我正在寻找一种执行字符串中代码的方法，如下面的示例，但使用 java。

 try {

   String Code = "rundll32 powrprof.dll, SetSuspendState";// the code we need to excecute

   Runtime.getRuntime().exec(Code);


} catch (IOException e) {
}

Answer 1

    String Code = "rundll32 powrprof.dll, SetSuspendState";

    StringBuffer output = new StringBuffer();

    Process p;
    try {
        p = Runtime.getRuntime().exec(Code);
        p.waitFor();
        BufferedReader reader = 
                        new BufferedReader(new InputStreamReader(p.getInputStream()));

                    String line = "";           
        while ((line = reader.readLine())!= null) {
            output.append(line + "\n");
        }

    } catch (Exception e) {
        e.printStackTrace();
    }

    System.out.println(output.toString());
