使用java执行批处理文件后无法关闭命令提示符

发布于 2024-10-10 19:00:29 字数 192 浏览 5 评论 0原文

我正在使用此行调用 build.bat 文件

rt.exec(new String[]{"cmd.exe","/C","start", "/MIN","build.bat"});

此行打开命令提示符。构建成功，但窗口保持打开状态。我该如何关闭它？尝试破坏进程和其他 System.ext 方法。没用

原文

I am invoking the build.bat file using this

rt.exec(new String[]{"cmd.exe","/C","start", "/MIN","build.bat"});

This line opens a command prompt. The build is successful but the window remains open.
How do I close it?
Tried destroying the process and other System.ext methods. no use

您不需要在参数中使用 start /MIN 。你试过这个吗？

rt.exec(new String[]{"cmd.exe","/C","build.bat"});

You shouldn't need to use start /MIN in your arguments. Have you tried this?

rt.exec(new String[]{"cmd.exe","/C","build.bat"});

在bat文件末尾添加exit，也无需在前面添加cmd即可直接执行bat

writer.write("expdp greenbuds/greenbuds directory=backup dumpfile="+dd+".dump logfile="+dd+".log");
writer.newLine();
writer.write("Exit");

writer.write("expdp greenbuds/greenbuds directory=backup dumpfile="+dd+".dump logfile="+dd+".log");
writer.newLine();
writer.write("Exit");

我刚刚开始，所以不能投票支持@Franci Penov 的答案是正确的：

rt.exec(new String[]{"cmd.exe","/C","build.bat"});

或者简单地说，

rt.exec("cmd.exe /C build.bat");

不应该弹出命令提示符。 build.bat 将无头执行。

假设您确实想在 build.bat 运行时调出命令提示符（这样您就可以直接从命令提示符看到输出，而不是稍后再处理），并且希望命令提示符消失build.bat 完成执行后，您可以使用以下命令：

rt.exec("cmd.exe /C start cmd.exe /C batch.bat");

start 启动一个（可见的）命令提示符窗口来处理和显示 cmd 的输出。 exe /C 批处理.bat。如果您在 batch.bat 末尾有一个 pause，那么您所需要做的就是按一个键，命令提示符就会消失，无需键入在提示窗口中exit将其关闭。

这可能不是您所需要的，但我一直在搜索，但后来自己找到了解决方案。只是为了分享。

I am just starting out here in SO, so couldn't upvote @Franci Penov's answer as correct:

rt.exec(new String[]{"cmd.exe","/C","build.bat"});

or simply,

rt.exec("cmd.exe /C build.bat");

should not bring up a command prompt. build.bat will be executed headlessly.

Suppose you do want to bring up a command prompt while build.bat is running (so you can see the output right from the command prompt instead of processing it later), and want the command prompt to go away after build.bat has finished execution, you may use the following:

rt.exec("cmd.exe /C start cmd.exe /C batch.bat");

the start starts a (visible) command prompt window to process and display the output of cmd.exe /C batch.bat. If you have a pause at the end of your batch.bat then all you need to do is hitting a key, and the command prompt will go away without the need to type exit at the prompt window to close it.

This may not be what you need, but I have been searching on SO but then found out the solution myself. Just to share it.
