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

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 24.4, “Profile-specific properties” for details.
