在跨平台Java中将文件存储在用户目录中 [英] Storing a file in the user's directory in cross-platform Java

问题描述

我有一个可以在Mac和Windows上运行的Java应用程序，无需安装即可直接从CD/DVD中获得.现在，我需要在本地文件系统上的某个位置存储一个包含每个用户数据(例如收藏夹等)的文件，以便可以将其写入.

I have a Java application that runs on Mac and Windows, directly off a CD/DVD with no installation. Now, I need to store a file containing per-user data (think favourites etc.) somewhere on the local file system, so that it can be written to.

那么，您认为该文件在哪里呢?我在想类似的东西:

So, where do you think is a good location for this file? I am thinking something like:

<USER_DOCUMENTS_AND_SETTINGS>/application data/myapp/favourites.db <USER_HOME_DIR>/.myapp/favourites.db for mac/nix

<USER_DOCUMENTS_AND_SETTINGS>/application data/myapp/favourites.db for windows <USER_HOME_DIR>/.myapp/favourites.db for mac/nix

有什么想法吗? 有人知道在Java中确定这些路径的最佳方法吗?

Thoughts? And does anyone know the best way to determine these paths within Java?

推荐答案

System.getProperty("user.home")
