Java中的ProcessBuilder [英] ProcessBuilder in Java

问题描述

我正在此页面上研究此主题，但找不到解决方案，如何使用ProcessBuilder在cmd中执行程序？我想使用命令行使用7zip压缩，打开，删除文件。
我有以下代码作为示例，但是不起作用，cmd启动但未创建压缩文件：

I´m studing about this subject in this page, but I can´t find the solution, how can I execute programs in cmd using ProcessBuilder? I want to compress, open, delete a file with 7zip using the command line. I have this code as example, but doesn´t work, cmd starts but doesn´t create the compress file:

String[] commands=
   {"cmd.exe", "7za", "a", "-t7z", "test.7z", "Test.txt", "/C", "start"};
ProcessBuilder pb = new ProcessBuilder(commands); 

推荐答案

问题在Java中有点（启动（ ）缺少），在7za中有点（命令行乱码）

The problem is a little bit in Java (start() missing), a little bit in 7za (command line garbled)

new ProcessBuilder("7za", "a", "-t7z", "test.7z", "Test.txt").start();

仅当7za位于您的路径中时，此命令才有效...

This command works only if 7za is in your PATH...

如果没有，则必须在Windows下指定其路径：

If not you have to specify its path, under Windows:

new ProcessBuilder(
   "C:/Program Files/7-Zip/7za.exe", "a", "-t7z", "test.7z", "Test.txt").start();

七个zip帮助：

7-Zip (A) 9.20  Copyright (c) 1999-2010 Igor Pavlov  2010-11-18
