Spring Profiles provide a way to segregate parts of your application configuration and
make it only available in certain environments. Any @Component or @Configuration can
be marked with @Profile to limit when it is loaded:
@Configuration @Profile("production") public class ProductionConfiguration { // ... }
In the normal Spring way, you can use a spring.profiles.active
Environment property to specify which profiles are active. You can
specify the property in any of the usual ways, for example you could
include it in your application.properties:
spring.profiles.active=dev,hsqldb
or specify on the command line using the switch --spring.profiles.active=dev,hsqldb.
The spring.profiles.active property follows the same ordering rules as other
properties, the highest PropertySource will win. This means that you can specify
active profiles in application.properties then replace them using the command line
switch.
Sometimes it is useful to have profile specific properties that add to the active
profiles rather than replace them. The spring.profiles.include property can be used
to unconditionally add active profiles. The SpringApplication entry point also has
a Java API for setting additional profiles (i.e. on top of those activated by the
spring.profiles.active property): see the setAdditionalProfiles() method.
For example, when an application with following properties is run using the switch
--spring.profiles.active=prod the proddb and prodmq profiles will also be activated:
--- my.property: fromyamlfile --- spring.profiles: prod spring.profiles.include: proddb,prodmq

Remember that the |
You can programmatically set active profiles by calling
SpringApplication.setAdditionalProfiles(…) before your application runs. It is also
possible to activate profiles using Spring’s ConfigurableEnvironment interface.
Profile specific variants of both application.properties (or application.yml) and
files referenced via @ConfigurationProperties are considered as files are loaded.
See Section 22.3, “Profile specific properties” for details.
