System.getProperty("user.dir") does not work
提问by Danilo M.
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.
我需要从我的项目中获取相对路径来上传照片，但是当我System.getProperty("user.dir");在我的测试中运行时，它返回/home/user/workspace/Myproject，但如果我从我的弹簧控制器运行它，它只会返回/home/user.
Can anyone provide a insight that probably is happening?
任何人都可以提供可能正在发生的见解吗？

The user.dirproperty is the current working directory where you are running Java. You're starting java in /home/user/workspace/Myprojectwhen 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?
该user.dir属性是您运行 Java 的当前工作目录。/home/user/workspace/Myproject当你运行你的项目时，你正在启动 java，但是当 Spring 运行它时，它不能保证是相同的工作目录。你在寻找user.home（应该总是/home/user）吗？
