Java 中的进程构建器 [英] ProcessBuilder in Java

问题描述

我正在本页研究这个主题，但找不到解决方案，如何使用 ProcessBuilder 在 cmd 中执行程序?我想使用命令行压缩、打开、删除带有 7zip 的文件.我将此代码作为示例，但不起作用，cmd 启动但不创建压缩文件:

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

问题是Java有点问题(start()缺失)，7za有点问题(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();

此命令仅当 7za 在您的 PATH 中时才有效...

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

如果不是你必须指定它的路径，在Windows下:

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
