如何使用从文件加载的环境变量运行java应用程序？

Question

I'm building java ( jdk 8 ) application.

I want to run the application (run/debug mode) from my IDE ( Intellij IDEA ).

My application use some environment variables.

I know I can add the environment variables one by one in the Run/Debug configurations -> environment variables.

• Is it possible to load all those environment variables from file (ie env.list file) ?
• How can I tell the IDE to load the environment variables from file when running the application in Run/Debug mode ?

Answer 1

Right now there is no choice like that in IDEs. We have to manually feed all those stuffs in the Run/Debug configuration. If you want you can add it as part of your gradle / maven from there you can do all those expected functionalitites and configure that task in the Run/Debug configuration. That only will solve your problem.

Answer 2

There is no direct way to do this.

The only things that comes to my mind is:

• I don't know the version of your IDEA but there are plugins for that like this one, EnvFile . But the format of these files are limited.

If you don't want to use it from directly from IDE you can code:

• Use can tinker with your build tool, like this one with Maven.
• Use can use properties . There is an example .
