Setting active profile and config location from command line in spring boot

Question

I have a spring boot application.

I have three profiles in my application-> development, staging and production. So I have 3 files

1. ap

Answer 1

When setting the profile via the Maven plugin you must do it via run.jvmArguments

mvn spring-boot:run -Drun.jvmArguments="-Dspring.profiles.active=production"

With debug option:

mvn spring-boot:run -Drun.jvmArguments="-Xdebug -Xrunjdwp:transport=dt_socket,server=y,suspend=n,address=5005 -Dspring.profiles.active=jpa"

I've seen this trip a lot of people up..hope it helps

Answer 2

Michael Yin's answer is correct but a better explanation seems to be required!

A lot of you mentioned that -D is the correct way to specify JVM parameters and you are absolutely right. But Michael is also right as mentioned in Spring Boot Profiles documentation.

What is not clear in the documentation, is what kind of parameter it is: --spring.profiles.active is a not a standard JVM parameter so if you want to use it in your IDE fill the correct fields (i.e. program arguments)

Answer 3

My best practice is to define this as a VM "-D" argument. Please note the differences between spring boot 1.x and 2.x.

The profiles to enable can be specified on the command line:

Spring-Boot 2.x (works only with maven)

-Dspring-boot.run.profiles=local

Spring-Boot 1.x

-Dspring.profiles.active=local

example usage with maven:

Spring-Boot 2.x

mvn spring-boot:run -Dspring-boot.run.profiles=local

Spring-Boot 1.x and 2.x

mvn spring-boot:run -Dspring.profiles.active=local

Make sure to separate them with a comma for multiple profiles:

mvn spring-boot:run -Dspring.profiles.active=local,foo,bar

mvn spring-boot:run -Dspring-boot.run.profiles=local,foo,bar

Answer 4

There's another way by setting the OS variable, SPRING_PROFILES_ACTIVE.

for eg :

SPRING_PROFILES_ACTIVE=dev gradle clean bootRun

Answer 5

We want to automatically pick property file based upon mentioned the profile name in spring.profiles.active and the path in -Dspring.config.location

application-dev.properties

If we are running jar in Unix OS then we have to use / at the end of -Dspring.config.location otherwise it will give below error.

Error :: java.lang.IllegalStateException: File extension of config file location 'file:/home/xyz/projectName/cfg' is not known to any PropertySourceLoader. If the location is meant to reference a directory, it must end in '/'

Example

java -Dspring.profiles.active=dev -Dspring.config.location=/home/xyz/projectName/cfg/ -jar /home/xyz/project/abc.jar

or

java -jar /home/xyz/project/abc.jar --spring.profiles.active=dev --spring.config.location=/home/xyz/projectName/cfg/
