How to create a Map> property in properties file that can be injectable using Spring's @Value

Question

How do I create a Map<String, List<String>> property in properties file that can be injectable using Spring's @Value?

Example code snippet in Properties java file

@PropertySource({"file:salesforce-service.properties"})
public class Properties {
    @Value("#{${student.hobbies}}")
    private Map<String, List<String>> hobbies;
}

@Mark Rotteveel, my question is different than the associate one. The question being asked is Map while my question is Map>. — Artanis Zeratul, Mar 22 '21 at 04:52
Although I see it as a variation on a theme, I agree that this might not be immediately obvious. — Mark Rotteveel, Mar 22 '21 at 08:16
