Profiles

JHipster comes with two Spring "profiles":

dev for development: it focuses on ease of development and productivity
prod for production: it focuses on performance and scalability

Those profiles come in two different configurations:

The Maven/Gradle profiles are used at build time. For example ./mvnw -Pprod package or ./gradlew bootRepackage -Pprod will package a production application.
The Spring profiles work at run time. Some Spring beans will behave differently, depending on the profile.

Spring profiles are set by Maven/Gradle, so we have a consistency between the two methods: you will have a "prod" profile on Maven/Gradle and Spring at the same time.

In default mode, JHipster will use the "dev" profile

If you run the application without Maven/Gradle, launch the "Application" class (you can probably run it easily from your IDE by right-clicking on it).

If you run the application with Maven, run ./mvnw to use our Maven Wrapper, or mvn to use your own Maven installation.

If you run the application with Gradle, run ./gradlew to use our Gradle Wrapper, or gradle to use your own Gradle installation.

In production, JHipster has to run with the "prod" profile

You can run JHipster in production directly using Maven or Gradle:

With Maven, run ./mvnw -Pprod (or mvn -Pprod)
With Gradle, run ./gradlew -Pprod (or gradle -Pprod)

If you want to package your application, in order to have an executable WAR file, you should also run Maven or Gradle with the "prod" profile:

With Maven, run ./mvnw -Pprod package (or mvn -Pprod package)
With Gradle, run ./gradlew -Pprod bootRepackage (or gradle -Pprod bootRepackage)

When you run your production application, don't forget to add the "prod" profile, by adding --spring.profiles.active=prod to your program arguments:

./java -jar jhipster-0.0.1-SNAPSHOT.war --spring.profiles.active=prod

Spring profiles switches

JHipster comes with two additionnal Spring "profiles" used as switches:

no-swagger to disable swagger
no-liquibase to disable liquibase

These can be used along with both dev and prod profiles. Please note that no-swagger doesn't have any effect on prod profile as swagger is disabled by default on that profile.

The are only used at run time:

In your IDE, run your main applcation class with spring.profiles.active=dev,no-swagger,no-liquibase (please note you need to activate the "dev" or "prod" profile explicitly)
With a packaged application: ./java -jar jhipster-0.0.1-SNAPSHOT.war --spring.profiles.active=prod,no-liquibase

With Maven, you can also use those profiles directly:

./mvnw -Pprod "-Drun.profiles=no-liquibase"
./mvnw "-Drun.profiles=no-liquibase,no-swagger"

With Gradle, you can also use those profiles directly:

./gradlew -Pprod -Pno-liquibase
./gradlew -Pno-liquibase -Pno-swagger
