如何在Java类中执行cmd命令？

问题描述：

我想用Java代码调用cmd命令。我说：

I want to call cmd command in java code. I say:

String str ="C:/uploaded_files/111.txt";
Process process = Runtime.getRuntime().exec(new String[]{"cmd.exe", "/c",str});
System.out.println(str);

也不要得到 111.txt 。奇怪的是，当这段代码在 jsp 中时，一切正常。可能是什么问题？

And dont get 111.txt. Its strange because when this code was in jsp all works fine. What can be wrong?

答

此代码有什么问题。一切正常。打开并显示文件111.txt

what's the problem with this code. It's perfectly working. opens and shows content of the file 111.txt

try {
    String str ="C:/uploaded_files/111.txt";
    Process process = Runtime.getRuntime().exec(new String[]{"cmd.exe", "/c",str});
    System.out.println(str);
    } catch (Exception ex) {}

请检查路径是否正确以及是否正确目录和文件不会丢失或拼写

please check whether the path is correct and whether the directories and files are not missed or spelled
