different configuration springboot

Generally speaking , Project development is divided into development environment (dev) Test environment (test) Preproduction environment (pre) Production environment (prod). There are some differences in configuration between different environments , We switch according to different deployment environment files , Let's talk about how to configure different environments .

Configuration file preparation

Prepare the corresponding application-*.properties file .

  • application.properties: Common configuration
  • application-dev.properties: Development environment configuration
  • application-test.properties: Test environment configuration
  • application-prod.properties: Production environment configuration


pom.xml To configure

<!-- Whether to replace @xx@ It means maven properties Property value -->


# At this point, the configuration is the development environment
# The test environment is configured at this time
# At this point, the configuration is the production environment

The above configuration requires us to modify the corresponding values in different environments , This is very inconvenient , At this point, we can configure it by variables , Now let's make some changes .

pom.xml Add

<!-- development environment -->
<!-- Test environment -->
<!-- Production environment -->

application.properties It is amended as follows

# At this point through env To distinguish between different environments

At this time we are IDEA On the right you see the following :

Here we can choose the corresponding environment


Now we can switch Profiles To switch the environment . But in this case, it can only be started by running the startup class , like this :


Only in this way can it be applied to Profiles Selected value .

spring-boot:run Mode start

It can't be applied to IDEA On the right Profiles Environmental value of .

  • mvn spring-boot:run -P dev

We need to add the specified environment after the command , like this :mvn spring-boot:run -P dev Specified in dev Start up in the environment of , among -P Appoint pom.xml Corresponding profiles Value . here application.properties The configuration file is no longer valid .

springboot1.x start-up

  • mvn spring-boot:run -Drun.profiles=dev

springboot2.x start-up

  • mvn spring-boot:run -Dspring-boot.run.profiles=test

function jar package

java -jar -Dspring.profiles.active=test demo.jar
# perhaps
java -jar --spring.profiles.active=test demo.jar
