Spring boot command line arguments with Maven
Running application with Maven
To run your application with Maven you just run the following command:
mvn spring-boot:runSpecifying profiles
You can specify an active profile for you Spring boot application with the following command for mvn
mvn spring-boot:run -Dspring-boot.run.profiles=local,devWhy using -D with mvn don't do anything
The Spring boot application is executed in a forked process, thus setting the properties with the command-line using -D for example will not affect the application. That is if you're running the application using maven.
How to set system property with maven
Like previously mentioned since the Spring boot application is executed in a forked process, if you set a system property using -D it will not be used in the actual application. To set a system property for the Spring boot application to use you will have to use
mvn spring-boot:run -Dspring-boot.run.jvmArguments="-Dproperty1=overridden"This is also how you set debugging properties for when maven actually executes with Java.
What if you want to run with java
If instead you opt to build the jar using maven and then run the Spring boot application with java command, then you can provide in the -D and it will be used appropriately within the application and not ignored due to forked process.
However, when you are building the jar file you must also provide in the -D system properties. The active profile that you want to build for will need to be provided as well under -Dspring.profiles.active maven CLI argument.
