Spring Boot: read list from yaml using @Value or @ConfigurationProperties

Question

I want to read a list of hosts from a yaml file (application.yml), the file looks like this:

cors:
    hosts:
        allow: 
            - http://foo1/
             


        

Answer 1

use comma separated values in application.yml

corsHostsAllow: http://foo1/, http://foo2/, http://foo3/

java code for access

@Value("${corsHostsAllow}")    
String[] corsHostsAllow

I tried and succeeded ;)
