I m not sure I fully understand the question but I ll attempt to answer by providing a few details about profiles in Spring Boot  For your  1 example  according to the docs you can select the profile using the Spring Boot Maven plugin using -Drun profiles  Edit  For Spring Boot 2 0  run has been renamed to spring-boot run and run profiles has been renamed to spring-boot run profiles mvn spring-boot run -Dspring-boot run profiles dev  https   docs spring io spring-boot docs 2 0 1 RELEASE maven-plugin examples run-profiles html From your  2 example  you are defining the active profile after the name of the jar  You need to provide the JVM argument before the name of the jar you are running  java -jar -Dspring profiles active dev XXX jar  General info  You mention that you have both an application yml and a application-dev yml  Running with the dev profile will actually load both config files  Values from application-dev yml will override the same values provided by application yml but values from both yml files will be loaded  There are also multiple ways to define the active profile  You can define them as you did  using -Dspring profiles active when running your jar  You can also set the profile using a SPRING PROFILES ACTIVE environment variable or a spring profiles active system property  More info can be found here  https   docs spring io spring-boot docs current reference html howto html howto-set-active-spring-profiles

Alternatively  the profile can be directly specified in the application properties file by adding the line  spring profiles active prod Profiles work in conjunction with Spring Boot properties files  By default  Spring Boot parses a file called application properties     located in the src main resources directory     to identify configuration information  Our first task will be to add a parameter in that file which will tell Spring to use a different environment-specific property file corresponding to the active profile  i e  the profile that the app is currently being run with   We can do this by adding the following to the application properties file  spring profiles active  activatedProperties  Now we need to create the two new environment-specific property files  in the same path as the existing application properties file   one to be used by the DEV profile and one to be used by the PROD profile  These files need to be named the following  application-dev properties application-prod properties In each case  we specify prod as the active profile  which causes the application-prod properties file to be chosen for configuration purposes

Create specific  yml files in the resources directory for each and every environment Eg  dev qa stg etc   that you need to run the application  image of  yml files in resources directory  If you are using spring-boot-maven-plugin 2 0 5 RELEASE in your pom xml file you can add the profiles within the dependency tag as follows  image of pom xml spring-boot-maven-plugin  you can configure multiple profiles using multiple profile tags   Then you can use the following commands to build and run the project   1  mvn clean install 2  mvn spring-boot run -Dspring-boot run default  qa   Then you will see that the default profile is set as qa while running the project  displaying the default profile when running the application

You don t need three  yml files for this  You can have a single application yml file and write profile specific properties in the same where each profile section is separated by 3 hyphen  ---   Next  for selecting the current active profile  you can specify that as well in your application yml file  like this    spring    profiles      active      - local   However  this configuration will be overriden if you set an Environment variable  eg   SPRING PROFILES ACTIVE   dev    Here is a sample file for you requirement     include common properties for every profile in this section  server port  5000   spring    profiles      active      - local  ---   profile specific properties  spring    profiles  local    datasource      url  jdbc mysql   localhost 3306      username  root     password  root  ---   profile specific properties  spring    profiles  dev    datasource      url  jdbc mysql    lt dev db url gt      username   lt username gt      password   lt password gt

The  Profile annotation allows you to indicate that a component is   eligible for registration when one or more specified profiles are   active  Using our example above  we can rewrite the dataSource   configuration as follows     Configuration  Profile  dev   public class StandaloneDataConfig         Bean     public DataSource dataSource             return new EmbeddedDatabaseBuilder                setType EmbeddedDatabaseType HSQL               addScript  classpath com bank config sql schema sql                addScript  classpath com bank config sql test-data sql                build              And other one    Configuration  Profile  production   public class JndiDataConfig         Bean destroyMethod         public DataSource dataSource   throws Exception           Context ctx   new InitialContext            return  DataSource  ctx lookup  java comp env jdbc datasource
