Mutally exclusive bean loading

I am using spring-boot and would like to conditionally load two beans based of what profile is passed. 

@Configuration
@Profile("secure")
public class Secured ... //this should only load when "secure" is supplied

@Configuration
public class NotSecured ... //this should be the default

So basically:

If the user passed --spring.profiles.active=secured I want the Secured bean to load but not the NotSecured bean. By default it should just load the NotSecured bean.

Is this possible?

You may also specify the default profile setting with this annotation explicitly:

  • @Profile("default")
  • or with a value like @Profile({"insecure","default"}

It's worth noting that any bean that does not specify a profile belongs to the default profile.

It surprised me to find that if you have several implementations for a service and one is annotated with @Primary and @Profile(...) the bean with the default profile will get injected if the profile is not configured (example configuration applications.properties: spring.profiles.active=val1,val2,...).

Said differently, when @Profile is used in any implementation, the @Primary annotation doesn't appear to be considered; and if no profile is defined, the default will be used (which could be an implementation without the @Profile annotation since that one becomes the default!).

You can use the '!' not operator, i.e. annotate the Bean/Configuration class with @Profile("!secure") and it will only be used when the 'secure' profile is not active.
