Question

这里我有以管理员身份保存启动命令行命令的String并停止Windows服务。它在控制台中说：输入管理员的密码：

String administratorCommandLine = "runas /profile /user:Administrator \"cmd.exe /c sc stop AcPrfMgrSvc\"";
Process runtimeProcess = Runtime.getRuntime().exec(administratorCommandLine);
runtimeProcess.waitFor();

BufferedReader stdInput = new BufferedReader(new InputStreamReader (runtimeProcess.getInputStream());

BufferedWriter stdOutput = new BufferedWriter(new OutputStreamWriter(
runtimeProcess.getOutputStream()));

当我想根据需要向命令行添加密码来告诉异常时：例外：java.io.IOException：管道正在关闭

System.out.println("Here is the standard output of the command:\n");
String s = null;
while ((s = stdInput.readLine()) != null) {
System.out.println(s);
if(s.startsWith("Enter the password for Administrator:") || s.startsWith("Zadejte heslo pro administrator:")) { 
stdOutput.append("password123").flush(); 
} 
}

有没有办法将密码放入该流中？

试试这段代码：

    String loggedInUser = System.getProperty("user.name");
    String pass="";

    String psexec = "C:\\Utils\\psexec.exe"; //location of psexec
    //Build the command line
    List<String> command = new LinkedList<String>();
    command.add(psexec);
    command.add("-u");
    command.add("Administrator");

    //request password if the user is not Administrator
    if(! loggedInUser.equalsIgnoreCase("Administrator")) {
        Scanner s = new Scanner(System.in);
        System.out.print("Password: ");
        pass = s.nextLine();
        if(! pass.trim().isEmpty()) {
            command.add("-p");
            command.add(pass);
        }
    }       

    command.add("cmd.exe");
    String[] cmdArgs = {"/c", "sc", "stop", "AcPrfMgrSvc"};
    command.addAll(Arrays.asList(cmdArgs));

    ProcessBuilder builder = new ProcessBuilder(command);
    Process process = builder.start();

    int returnCode;

    try {
        returnCode = process.waitFor();
    } catch (InterruptedException e) {
        returnCode = 1;
    }

PS：我知道将密码读作字符串使用Scanner是不安全的，不是一个好主意。我上面的代码主要是为了演示如何使用PsExec以管理员身份停止Windows服务。您应该使用更好的版本替换密码阅读代码，如http://docs.oracle.com/javase/tutorial/essential/io/cl.html
