如何在不同目录中运行bat文件 [英] How to run bat file in different directory

问题描述

我有一个 bat 文件，它运行一个名为 Systemm.java 的 java 程序，位于一个名为 tp3

的包中

我的文件组织如下

<预><代码>.├── src├── tp3│ ├── Systemm.java│ ├── Communication.java│ └── exec_server.bat└── teste.bat

所以，我的主要问题是，我使用 teste.bat 来运行我的类 Systemm.java.这个蝙蝠很好用.

我还想做的是在 java 中调用 exec_server.bat.

依次:

• teste.bat 运行 Systemm.java
• Systemm.java 有一个类 Communication.java 的实例
• 这个实例运行一个应该运行 exec_server.bat 的方法

通信executeServer()方法

public void executeServer() {尝试 {//小路Process p = Runtime.getRuntime().exec("cmd/c start \"\" tp3\exec_server.bat");p.waitFor();System.out.println(我完成了你的服务器运行");} catch (IOException | InterruptedException e) {e.printStackTrace();}}

但是，当我运行我的程序时，此方法在 cmd 上显示此消息

我几乎是探索 cmd 和 bat 文件的新手，所以我真的很困惑我做错了什么.

非常感谢您提前提供帮助！

P.S:我在 src 目录上调用 cmd，exec_server.bat 只回显消息你好！"；在 cmd 上

解决方案

请提供完整路径试试:

 进程 p = null;尝试 {p = Runtime.getRuntime().exec("cmd/c start D:\\practice\\P1\\samp.bat ");} catch (IOException e) {//TODO 自动生成的 catch 块e.printStackTrace();}

I have a bat file which runs a java programm called Systemm.java, located within a package called tp3

My file organization is as follows

.
├── src
    ├── tp3
    │   ├── Systemm.java
    │   ├── Communication.java
    │   └── exec_server.bat
    └── teste.bat

So, my main problem is, I'm using teste.bat to run my class Systemm.java. And this bat works fine.

What I am also trying to do is call exec_server.bat in java.

Sequentially:

• teste.bat runs Systemm.java
• Systemm.java has an instance of class Communication.java
• This instance runs a method that should run exec_server.bat

Communication executeServer() method

public void executeServer() {
        try {
            // Path 
            Process p = Runtime.getRuntime().exec("cmd /c start \"\" tp3\exec_server.bat");
            p.waitFor();
            System.out.println("I finished running your server");
        } catch (IOException | InterruptedException e) {e.printStackTrace();}
    }

However when I run my programm, this method displays this message on cmd

I am pretty much the newbie exploring cmd and bat files, so I am really confused as to what am I doing wrong.

Thank you so much for any help in advance!

P.S: I' calling cmd on the src directory, and exec_server.bat only echos the message "Hi there!" on cmd

解决方案

Please try with by giving full path:

  Process p = null;
    try {
        p = Runtime.getRuntime().exec("cmd /c start D:\\practice\\P1\\samp.bat ");
    } catch (IOException e) {
        // TODO Auto-generated catch block
        e.printStackTrace();
    }
