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    application-development yml application-staging yml application-production yml   My application yml resides inside src main resources  I have set the active profile in application yml as    spring    profiles active  development   The other 3 profile specific config files are present in C  config folder    I am using gradle plugin for eclipse  When I try to do a  bootRun   I am setting the command line arguments in my gradle configuration in eclipse as    -Dspring profiles active staging -Dspring config location C  Config   However  the command line property is not getting reflected and my active profile is always getting set as development which is the one that I have mentioned in the applications yml file   Also C  Config folder is not searched for profile specific config files   I think I am missing something here  I have been trying to figure it out for the  past 2 days  But no luck  I would really appreciate any help

There are two different ways you can add override spring properties on the command line  Option 1  Java System Properties  VM Arguments  It s important that the -D parameters are before your application jar otherwise they are not recognized  java -jar -Dspring profiles active prod application jar  Option 2  Program arguments java -jar application jar --spring profiles active prod --spring config location c  config

I had to add this   bootRun       String activeProfile    System properties  spring profiles active       String confLoc   System properties  spring config location       systemProperty  spring profiles active   activeProfile     systemProperty  spring config location    file  confLoc      And now bootRun picks up the profile and config locations   Thanks a lot  jst for the pointer

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

-Dspring profiles active staging -Dspring config location C  Config   is not correct   should be   --spring profiles active staging --spring config location C  Config

My best practice is to define this as a VM  quot -D quot  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

I think your problem is likely related to your spring config location not ending the path with       Quote the docs     If spring config location contains directories  as opposed to files  they should end in    and will be appended with the names generated from spring config name before being loaded     http   docs spring io spring-boot docs current reference htmlsingle  boot-features-external-config-application-property-files

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
