使用java程序执行cmd命令

Question

我想使用java程序执行以下命令。 ＆＃34; java -jar Demo.jar readExcelDemo.Hvd＆＃34;

public class ExcelDriver {
    public static void main(String[] args) throws IOException {
        Runtime runTime = Runtime.getRuntime();
        Process process = runTime.exec("cmd","/c", "cmd.exe","java -jar Demo readExcelDemo.Hvd");

            }
}

Answer 1

创建包含内容的.bat或.cmd文件 java -jar演示readExcelDemo.Hvd

将您的代码更改为

public class ExcelDriver {
public static void main(String[] args) throws IOException {
    Runtime runTime = Runtime.getRuntime();
    Process process = runTime.exec("cmd","/c", "myfile.cmd");

        }

}

Answer 2

试试这个：

Runtime runTime = Runtime.getRuntime();
Process process = runTime.exec("java -jar Demo.jar readExcelDemo.Hvd");

如果以上代码不合适，请尝试以下操作：

Runtime runTime = Runtime.getRuntime();
Process process = runTime.exec("cmd.exe /c start java -jar Demo.jar readExcelDemo.Hvd");

如果您想观看cmd，可以使用以下代码。 由于/ c标志，它会立即关闭。

 Process p = runTime.exec("cmd.exe /c start cmd /k java -jar Demo.jar readExcelDemo.Hvd");

Answer 3

您可以致电：

Runtime.getRuntime().exec(command);
