java - java中的CMD.exe命令没有终止

Question

我正在尝试使用 cmd.exe 在特定目录中搜​​索文件，然后在 java 程序中显示路径并将其写入文件。问题是进程永远不会终止。

这是我的代码:

String[] str = new String[] { "cmd.exe ", "cd c:\\",
                        " dir /b /s documents", "2>&1" };

            Runtime rt = Runtime.getRuntime();
            try{

                Process p = rt.exec(str);
                InputStream is =p.getInputStream();
                InputStreamReader in = new InputStreamReader(is);


                StringBuffer sb = new StringBuffer();
                BufferedReader buff = new BufferedReader(in);
                String line = buff.readLine();
                while( line != null )
                {
                    sb.append(line + "\n");
                    line = buff.readLine();
                }
                System.out.println( sb );
                File f = new File("test.txt");
                FileOutputStream fos = new FileOutputStream(f);
                fos.write(sb.toString().getBytes());
                fos.close();

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

请试试

cmd /c

而不是简单地

cmd
