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:

files, profile-specific properties can also be defined using the naming convention
application-{profile}.properties. You are advised to only use lower case filenames and lower case profile names because Spring profile names are case sensitive. The Environment has a set of default profiles (by default [
default]) which are used if no active profiles are set (i.e. if no profiles are explicitly activated then properties from
application-default.properties are loaded).
Profile-specific properties are loaded from the same locations as standard

, with profile-specific files always overriding the non-specific ones irrespective of whether the profile-specific files are inside or outside your packaged jar.

Spring profiles can be activated via JVM argument spring.profiles.active. When a

in the config location directory. The

An example bootstrap.properties file

When it runs it will pick up the external configuration from the default local config server on port 8888 if it is running. To modify the startup behavior you can change the location of the config server using bootstrap.properties
