@Value annotation should be able to inject List<String> from YAML properties [SPR-11759]

Adam Berlin opened SPR-11759 and commented

Yaml file —

 
foobar:  
  ignoredUserIds:
    - 57016311
    - 22588218

Class —

 
    
public class Foobar {
    @Value("${foobar.ignoredUserIds}")
    List<String> ignoredUserIds;
}
 

Error —

 
Caused by: org.springframework.beans.factory.BeanCreationException: Could not autowire field: java.util.List foobar.Foobar.ignoredUserIds; nested exception is java.lang.IllegalArgumentException: Could not resolve placeholder 'foobar.ignoredUserIds' in string value "${foobar.ignoredUserIds}"

2021 and it’s still needed 😉

2019 and I need this feature. @Value >>>>> @ConfigurationProperties when there is only one field : private List<String> someList;

Why I need a Class when I only have one field?
