如何从系统变量设置Spring配置文件？ [英] How to set Spring profile from system variable?

问题描述

我有一个使用另一个项目的Spring项目。每个项目都有自己的spring配置文件，使用 applicationContext.xml 和 *。properties 为每个配置文件初始化java代码。我从 args [] 注入配置文件。 问题是第二个项目使用 applicationContext.xml中的env的默认配置
我无法从<\\ n注入env code> args [] 到第二个项目，我试着找一篇文章来解释Spring profile的工作原理。

I have a Spring project which uses another project. Each project has its own spring profile initialize from java code using applicationContext.xml and *.properties for each profile. I inject the profile from args[]. The problem is that second project uses the default configuration for the env from the applicationContext.xml I can not inject the env from args[] to the second project and I tried looking for an article which will explain how Spring profile works.

1. 当在 applicationContext.xml 中配置默认​​值时，是否存在一个层次结构，它将在该层次结构中查看配置文件？


2. System var是否强于 applicationContext.xml 配置？


3. 您认为我的挑战的最佳解决方案是什么？

1. Is there a hierarchy on which it will look the profile when default is not configured at applicationContext.xml ?
2. Is System var stronger than applicationContext.xml configuration?
3. What you think is the best solution to my challenge?

关于该主题甚至示例的文章将非常感谢!!
提前致谢。

Articles on that subject or even examples would be most appreciated!! Thanks in advance.

推荐答案

SPRING_PROFILES_ACTIVE是覆盖/选择Spring配置文件的环境变量

SPRING_PROFILES_ACTIVE is the environment variable to override/pick Spring profile
