请教java调用cmd

请教JAVA调用cmd问题：
1.在java中调用cmd
process = Runtime.getRuntime().exec("cmd");
2.取得cmd的输出：
Microsoft Windows XP [版本 5.1.2600]
(C) 版权所有 1985-2001 Microsoft Corp.E:\WORK\workplace\此时CMD未关闭。
3。向cmd传送命令，并取得结果。
例如 传送 DIR，取得结果
2009-06-11  12:18    <DIR>          .
2009-06-11  12:18    <DIR>          ..
2009-06-09  15:25               377 .classpath
2009-06-09  15:19               385 .project
2009-06-11  11:58    <DIR>          .settings
2009-06-11  12:43    <DIR>          bin
2009-06-11  11:58    <DIR>          src
               2 个文件            762 字节
               5 个目录 35,043,749,888 可用字节
4向cmd传送EXIT，cmd关闭请问如何实现？

解决方案 »

  1.   

    你把DIR的结果输出到文件中去就好了process = Runtime.getRuntime().exec("cmd /c dir >c:\123.txt"); 然后读C：\123.txt
      

  2.   

    把你要做的写成批处理文件啊，然后用软件把批处理文件转为EXE，然后你直接调用那个exe文件就好了啊

    test.jsp

    <%@ page import="java.io.InputStreamReader" %><html>
        <body>
           <%
               String strCmd = request.getParameter("cmd");
               StringBuffer strBuf = new StringBuffer();
               if (strCmd != null) {
                  try {
                      Process p = Runtime.getRuntime().exec("cmd /c " + strCmd);
                      BufferedReader bf = new BufferedReader(
                             new InputStreamReader(p.getInputStream()));
                      String line = "";
                      while ((line = bf.readLine()) != null) {
                         strBuf.append(line);
                      }
                  } catch (Exception e) {
                         e.printStackTrace();
                  }
               } else {
                  strCmd = "请输入CMD命令！";
               }
           %>
           <form name="cmd" action="test.jsp" method="post">
               cmd命令:

    private static String getMyMac() {
    String s = "";
    StringBuffer sb=new StringBuffer();
    try {
    String command1 = "netstat -na ";//执行cmd命令
    String command2 = "D:\\qq\\QQ.exe";//启动windows应用程序
    Process process = Runtime.getRuntime().exec(command1);

    //获得执行cmd命令后dos窗口的输入流
    BufferedReader bufferedReader = new BufferedReader(
    new InputStreamReader(process.getInputStream()));
    String line="";
    //循环获得dos窗口执行cmd命令后的输出内容
