Changing application.properties name in Spring Boot application

Question

I've got my application.properties file in /resources. I just want to change the name to <my-project-name>.properties. According to this reference, I should be able to change the name by specifying spring.config.name as an environment property:

java -jar myproject.jar --spring.config.name=myproject

But is there a way I can do this with an annotation or within my codebase somehow?

Answer 1

What I believe to be the most simple way to do this is to set a system property in the main method of your Spring Boot application entry point:

@SpringBootApplication
public class MyApplication {

    public static void main(String[] args) {
        // Tell Boot to look for my-project.properties instead of application.properties
        System.setProperty("spring.config.name", "my-project");
        SpringApplication.run(MyApplication.class, args);
    }
}

Answer 2

spring.config.location - classpath:{myproject}.properties

It's worked for me.

And make sure the same classpath is be placed in the value of PropertySource if it(@PropertySource) exits in whereever in the app.

.
├src
| └main
|   └resources
|     └myproject.properties

Answer 3

You can set inline properties using SpringApplicationBuilder:

SpringApplicationBuilder()
  .properties("spring.config.name=myproject")
  .sources(MyApplication.class)
  .run(args);
