Using @Value with condition in spring in order to map value to string

Question

I have a application.properites file with the following:

xxx.xxx = sandbox
xxx.sandbox = 123
xxx.production = 456

I would like to map to a string value 123 in case xxx.xxx == sandbox and 456 in case xxx.xxx == production

...
public class temp { 

 @Value("${??????}")
    private String token;
}

is it possible to fill in a condition incited of the ?????? that will map the token to 123 or 456 according to xxx.xxx ?

Use profiles instead, loading the appropriate property files for each. – Bracing

Answer 1

A simple way in case someone will hit this question:

@Value("#{'${xxx.xxx}'=='sandbox' ? '${xxx.sandbox}' : '${xxx.production}'}")

I just think it is much easier that start working with profiles.

Aweswome! I was missing the quotes around the inner '${xxx.xxx}' – Lenardlenci

Answer 2

You can use Spring Profiles, so you can have a property file for each enviroment.

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

after i'm using the above profile technic, how should i map the xxx.sandbox or xxx.production according to the profile from the application.properites file? – Disaccharide

What kind of application are you running ? You can use this property -Dspring.profiles.active=production" at the moment you run the application – Josphinejoss

OK, but these profile can help you to map the beans for spring, how i can use it to map in case of profile x use xxx.production, in case of profile y use xxx.sandbox? – Disaccharide

You can use something like this <beans profile="dev"> <util:properties id="myproperties" location="WEB-INF/dev.properties" /> </beans> <beans profile="qa"> <util:properties id="myproperties" location="WEB-INF/qa.properties" /> </beans> at the end, thats depends on how are you reading the properties – Josphinejoss
