exit the batch file after running using java
提问by hhafez
I know how to start the batch file using java code. When i run the batch file command prompt is opened. To close the command prompt i am using the taskill /im cmd.exe. but the problem is that the command prompt that is used to start the jboss is also closed. i want to kill the cmd with a particular process id. How do i get the process id of a particular cmd promt and kill that using java
我知道如何使用 java 代码启动批处理文件。当我运行批处理文件时，命令提示符被打开。要关闭命令提示符，我正在使用 taskill /im cmd.exe。但是问题是用来启动jboss的命令提示符也关闭了。我想用特定的进程 ID 杀死 cmd。我如何获取特定 cmd promt 的进程 ID 并使用 java 杀死它

Run the batch file with cmd.exe /c job.bat. The /cswitch carries out the command and then terminates the command interpreter.
运行批处理文件cmd.exe /c job.bat。该/c开关执行该命令，然后终止该命令解释程序。

can't you add exitto your batch file to exit it's own command prompt. Uisng taskill seems overkill for just closing one command prompt, don't you think?
您不能添加exit到批处理文件以退出它自己的命令提示符。Uisng taskill 仅仅关闭一个命令提示符似乎有点矫枉过正，你不觉得吗？
PS: I've never worked on batch files just the command prompt so I'm assuming it accepts the same commands.
PS：我从来没有在命令提示符下处理过批处理文件，所以我假设它接受相同的命令。

Here is the solution that works: to close command window after executing the commands from the batch (.bat) file you need to add "exit" (without the quotes) in a new line of your batch file. If you want to delay the execution this is the way and it works:
这是有效的解决方案：在执行批处理 (.bat) 文件中的命令后关闭命令窗口，您需要在批处理文件的新行中添加“exit”（不带引号）。如果你想延迟执行，这就是它的工作方式：
public class TestSleep
{
public static void main ( String [ ] args )
{
System.out.println("Do this stuff");
try
{
Thread.currentThread().sleep(3000);
}
catch ( Exception e ) { }
System.out.println("Now do everything after this");
}
}
Cheers
干杯

If you start the batch file with Runtime.exec(), it returns you a Process object. Calling the destroy() method will kill that process.
如果您使用 Runtime.exec() 启动批处理文件，它会返回一个 Process 对象。调用 destroy() 方法将终止该进程。

I too had the same problem. I first used as
我也有同样的问题。我首先用作
Runtime.getRuntime().exec("cmd.exe start /c test.bat");
Then I tried as below. It works fine.
然后我尝试如下。它工作正常。
Runtime.getRuntime().exec("cmd.exe /c start test.bat");
Try this.
试试这个。

Although this seems to be an old question and probably resolved.. I struggled with the same thing for a long time.. Finally this works
虽然这似乎是一个老问题并且可能已经解决了..我在同样的事情上挣扎了很长时间..最后这有效
String command = "cmd.exe /c build.bat";
Runtime rt = Runtime().getRuntime();
Process pr = rt.exec(command);
