spring-boot中如何使用环境变量

Question

I want to load properties from external file present under my home directory. I set a environment variable using the file as follows

export ENV_HOME=/home/usr/environment.properties

I want to use the properties present in environemnt.properties files in spring-boot application. I don't want to include this in packed jar

How to achieve this?

Answer 1

在控制器中使用 @PropertySource("${ENV_HOME}") 将覆盖来自外部文件的属性。
