Inject a list of maps from application.yml into service - groovy

Question

I am trying to inject a list of maps from my application.yml configuration file into my Spring Boot service. Here is the configuration in application.yml:
devoxx:
cfpApis:
-
url: http://cfp.devoxx.be/api/conferences
youtubeChannelId: UCCBVCTuk6uJrN3iFV_3vurg
-
url: http://cfp.devoxx.fr/api/conferences
-
url: http://cfp.devoxx.ma/api/conferences
youtubeChannelId: UC6vfGtsJr5RoBQBcHg24XQw
-
url: http://cfp.devoxx.co.uk/api/conferences
-
url: http://cfp.devoxx.pl/api/conferences
And here is my property in my service:
#Value("devoxx.cfpApis")
List<Map<String,String>> cfpApis
But there must be something wrong because when I try to run my application, I get the following exception:
java.lang.IllegalStateException: Cannot convert value of type [java.lang.String] to required type [java.util.Map]: no matching editors or conversion strategy found
Any idea of what I'm doing wrong?
FYI, I'm trying to migrate a Grails 3 project into a vanilla Spring Boot project and this configuration works in Grails 3, but Grails has its own YAML processors.

Thanks to #Morfic's comment, here is how i ended up solving that problem.
I tagged my service class with #ConfigurationProperties(prefix="devoxx") annotation. And in my service, I now have a property called cfpApis, with the following declaration:
List<Map<String,String>> cfpApis
And this works great.
