Making dotenv variables globally available

See original GitHub issue

I was wondering if there was any way to make the variables in the .env file globally available throughout my entire java application.

It seems as though configuring and loading the variables returns a Map of sorts from which you can retrieve all of the values. However I have to configure and load this variable in every file from which I wish to use it.

Dotenv env = Dotenv.configure().directory("./").load();

Is there any way I can load them once and use them everywhere? Perhaps even through the native System.getenv() static method? Running the configuration and loading once from my public static main method or something.

I build my own little util class if you’re interested. I used this class to normalise the configuration for Dotenv throughout my app too.

import io.github.cdimascio.dotenv.Dotenv;

public class Config {
	private static final Config instance = new Config();
	public static Config getConfig () {
		return instance;
	private Dotenv env;
	public Config () {
		this.env = Dotenv.configure().directory("./").ignoreIfMissing().load();
	public String get (String variable) {
		return env.get(variable);

@jessevdp are you using a framework? If not, your Config class might have to do. But if yes, you might want to find a way to fit dotenv into there in a properly integrated fashion. Here is my example using Spring

Beyond a simple static helper, I’m not sure that java-dotenv should do too much.
