System.getProperty(" user.dir")不起作用 [英] System.getProperty("user.dir") does not work
问题描述
我需要从我的项目获取上传照片的相对路径,但是当我在我的测试中运行 System.getProperty(user.dir);
时,它返回 / home / user / workspace / Myproject
,
但是如果我从我的spring控制器运行它,它只返回 / home / user
。
I need to get relative path from my project to upload photos, however when I run System.getProperty("user.dir");
in my test, it returns /home/user/workspace/Myproject
,
but if I run it from my spring controller, it just returns /home/user
.
任何人都可以提供可能正在发生的见解吗?
Can anyone provide a insight that probably is happening?
推荐答案
user.dir
属性是运行Java的当前工作目录。当你运行项目时,你在 / home / user / workspace / Myproject
中启动java,但是当Spring运行它时,它不能保证是相同的工作目录。您是在寻找 user.home
(应该总是 / home / user
)?
The user.dir
property is the current working directory where you are running Java. You're starting java in /home/user/workspace/Myproject
when you run your project but when Spring runs it, it's not guaranteed to be the same working directory. Are you looking for user.home
(which should always be /home/user
) instead?
