Spring load prod profile

Question

I have a Spring application that I have to deploy in production. Unfortunately I am unable to turn the prod profile on. I have an application-dev.yml and application-prod.yml file as well as application.yml. My application.yml is as follows:

# ===================================================================
# Spring Boot configuration.
#
# This configuration will be overridden by the Spring profile you use,
# for example application-dev.yml if you use the "dev" profile.
#

So you can see I have spring.profiles.default and spring.pofiles.active set to prod. I also tried to build the app with maven and the option -Dspring.profiles.active=prod but despite this each time I run the war generated it says The following profiles are active: swagger,dev.

Anyone has a idea why the prod profile is not loaded ? Thanks in advance.

Answer 1

I've verified on spring-boot 2.1.4 the following configurations:

application.yaml:

spring:
 profiles:
   active: dev

application-dev.yaml:

sample:
  value: development

application-prod.yaml:

sample:
  value: production

And the following (very simple) spring boot application:

package com.example.demo;

import org.springframework.beans.factory.annotation.Value;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.boot.context.event.ApplicationStartedEvent;
import org.springframework.context.event.EventListener;

@SpringBootApplication
public class DemoApplication {

    @Value("${sample.value}")
    private String sampleValue;
    public static void main(String[] args) {
        SpringApplication.run(DemoApplication.class, args);

    }

    @EventListener
    public void onAppStarted(ApplicationStartedEvent evt) {
        System.out.println("Sample Value: " + sampleValue);
    }

}

This configuration works, even if I don't supply any flags: java -jar myapp.jar

So there must be something else here, related to your code.

Its hard to say whats wrong without seeing the application, however I did found one "suspicious" statement:

You say, that no matter what you try:

The following profiles are active: swagger,dev

Now where does the 'swagger' profile come from? I don't see any reference to it. If you run the application with java -jar myapp.jar one possibility I can see is that there is somewhere spring.factories file that defines an EnvironmentPostProcessor - its a hook where you can "fiddle" with profiles and, among other things add active profiles "manually" (in code).

So please check this possibility, but again - what you've done is correct in spring boot (well, technically you don't need spring.profiles.default entry but it doesn't harm)

Answer 2

Spring Boot can load the same properties from many locations , which you can refer its loading order in the docs at here.

The upper part in the list have a higher loading priority than the lower part.That means what you define in the application-xxx.yml can be overridden by the same properties that are also defined in the OS env variable or JVM properties or etc .....

As the command line arguments has a pretty high loading order , which means basically you can try to use it to set the profile by adding --spring.profiles.active=prod to the command that start the application such as :

$ java -jar myproject.jar --spring.profiles.active=prod
