In my project I have seperate application.yml files for each environments, inside each folder for an environment.

NOTE: Below red color yml file made temporarily, to make the code work. But should remove this after fixing. So what I want is to use separate application.yml file according to environment. Specially I need to use local/application.yml for local development

Below has an example of getting env variables in my project

@Component
@Configuration
public class ApplicationProperties {
    @Value("${ex.my.url}")
    private String myServiceUrl;
   // getters setters and nedded stuff
}

But it doesn't work, since could not find a way to mention the needed environment. Because it is in a seperate folder. All the other examples mention the way to get the yml file inside resource folder, without seperate folders.

Any fix for the issue?

in my projects, I specify a profile with the VM option : -Dspring.profiles.active=local

Then I have a file named application-local.yml

in production : -Dspring.profiles.active=prod , will use the file application-prod.yml

Spring Boot Environment, Environment is an interface representing the environment in which the current application is running. It can be use to get profiles and properties of� When Spring Boot initializes its environment, it uses properties files, YAML files, environment variables, and command-line arguments to externalize the configuration. In this post, we will see how to read the system environment variable. 1. Spring’s Environment Interface

In the resources folder

Do make file of application.yml, application-local.yml, application-dev.yml etc.. what ever you want

and then in application.yml

 spring.profile.active = ${ENV}

now during the run specify the ENV variables from run/debug configuration under Intellij or mention the profile for which you want to build the jar in application.yml.

Alternative, you can use the -D spring.profile.active=dev

Using environment variables with Spring Boot, This post will cover how you can use OS environment variables to pass configuration values to a Spring Boot application. you can provide a default value which will be used if the environment variable is not found. As with the @Value annotation, you can provide a default value which will be used if the environment variable is not found. api.key=${API_KEY:123abc} SPRING_APPLICATION_JSON. At application startup, Spring Boot will look for an environment variable called SPRING_APPLICATION_JSON. It can be used to provide a set of application properties using

24. Externalized Configuration, You can use properties files, YAML files, environment variables and command- line Files specified in spring.config.location are used as-is, with no support for� Spring attempts to unify all name/value property pairs access into org.springframework.core.env.Environment. The properties source can be java.util.Properties, loaded from a file or Java system/env properties or java.util.Map.

The classic solution is to setup one config file (I prefer properties because I'm sane) and allow for an overrides file to be placed on each installed host.

Spring supports this out-of-the-box.

Here is an example:

public static void main(final String[] argumentArray)
{
  final StringApplicationBuilder springApplicationBuilder;

  springApplicationBuilder = new SpringApplicationBuilder(YourSpringBootApplication.class)

  springApplicationBuilder.properties(
    "spring.config.location=classpath:/yourConfig.properties,/some/path/to/overrides/directory/yourConfig.properties");

  springApplicationBuilder.build().run(argumentArray);
}

59. Properties & configuration, A SpringApplication has bean properties (mainly setters) so you can use its Java API and then the Spring Boot banner will not be printed on startup, and the You can also provide System properties (or environment variables) to change the � Spring 3.1 also introduces the new @PropertySource annotation, as a convenient mechanism for adding property sources to the environment.This annotation is to be used in conjunction with Java-based configuration and the @Configuration annotation:

It was about the recommended format for environment variables (uppercase separate by _) not working for spring.config.additional-location. If you were referring to my comment, that was just a workaround till the fix was available.

Environment Variables (The Java™ Tutorials > Essential Classes , Many operating systems use environment variables to pass configuration information to applications. Like properties in the Java platform, environment variables are key/value pairs, where If the variable is not defined, getenv returns null . Environment variables declared inside a shell command run step, for example FOO=bar make install, will override environment variables declared with the environment and contexts keys. Environment variables added on the Contexts page will take precedence over variables added on the Project Settings page.

  • Thats what i found from internet also. But in this case the file name is not something like, "application-dev.yml". It is like application.yml which inside dev/ folder. That is the issue.
  • Is there a reason you cannot rename the files ?
  • Yeah. Also renaming won't work without putting all those files just inside resources folder. Isn't it?
  • Well, in my project application-*.yml files are in resources/config, so I think it should work. edit : nvm it seems config is a special case
  • I didn't get. Can you explain how you access yml s' inside config folder.
  • What I want is to maintain this folder structure. Instead of putting all applications.yml files together inside resources directory.
