使用java程序运行批处理文件

当我运行这段代码时，我只得到了命令promt。bat文件未运行。 如何使用此代码执行批处理文件

提前感谢

让您的“test.bat”如下所示：

try {                               
try {
    String[] command = {"cmd.exe", "/C", "Start", "D:\\test.bat"};
        Runtime r = Runtime.getRuntime();
        Process p = r.exec(command);
        p.waitFor();

    } catch (Exception e) {
        e.printStackTrace();
        JOptionPane.showMessageDialog(this, "Error" +"Execution!","Error",JOptionPane.ERROR_MESSAGE);
        }
    } catch (IOException ex) {
        Logger.getLogger(DBBackUp.class.getName()).log(Level.SEVERE, null, ex);
    }

try
{
 Runtime r = Runtime.getRuntime();
 Process p = r.exec("rundll32 url.dll,FileProtocolHandler " + "D:\\test.bat");
 p.waitFor();
}catch(Exception ex){ex.printStackTrace();}

然后，您可以按如下方式执行此批处理文件：

dir
pause

您可以尝试以下方法：

try {                               
try {
    String[] command = {"cmd.exe", "/C", "Start", "D:\\test.bat"};
        Runtime r = Runtime.getRuntime();
        Process p = r.exec(command);
        p.waitFor();

    } catch (Exception e) {
        e.printStackTrace();
        JOptionPane.showMessageDialog(this, "Error" +"Execution!","Error",JOptionPane.ERROR_MESSAGE);
        }
    } catch (IOException ex) {
        Logger.getLogger(DBBackUp.class.getName()).log(Level.SEVERE, null, ex);
    }

try
{
 Runtime r = Runtime.getRuntime();
 Process p = r.exec("rundll32 url.dll,FileProtocolHandler " + "D:\\test.bat");
 p.waitFor();
}catch(Exception ex){ex.printStackTrace();}

您可以分享您的test.bat和命令提示符响应吗。尝试在批处理文件中添加回显消息作为第一条语句，以查看它是否正在运行。如果bat文件是一个短时间运行的脚本，则可能无法看到该窗口。请共享test.bat和命令提示符响应。尝试将回显消息作为批处理文件中的第一条语句添加，以查看它是否正在运行。如果bat文件是短时间运行的脚本，则可能无法看到该窗口。
