在Spring Boot中使用dotenv文件

问题描述：

我想使用dotenv文件配置我的Spring Boot应用程序.

I'd like to use dotenv files to configure my Spring Boot application.

做到这一点的最佳方法是什么?

What is the best way to do this?

在 Ruby 或节点世界，我只是创建了 .env 文件，它将所有内容从那里加载到应用程序环境中.

In Ruby or Node world, I just creating .env file and it loads all stuff from there to application environment.

我不喜欢为应用程序等创建单独的配置文件.我只想将文件中指定的所有环境变量加载到应用程序中.

I don't like to create separate profiles for my app etc. I just want to load any environment variables I specified in file into my app.

我已经在Spring和

I have built a proper integration between Spring and dotenv.

按照此线程理解动机.然后查看库:

Follow this thread to understand the motivation. And then review the library:

在此处查看spring-dotenv库:

该库包含一个示例应用程序，向您展示如何使用它，并且在那里您看到与Spring的集成非常自然:

The library includes a sample application to show you how to use it, and there you see that the integration with Spring is very natural:

在设计该库时，我坚持两个原则:

I stuck to two principles in designing this library:

允许您的代码完全不了解dotenv，以便您继续使用常规的Spring技术来引用application.yml/application.properties文件.没有可笑的事.
