@ConfigMapping @WithConverter and application.yaml

[flicus]

Hello, i am trying to have this configuration in my application.yaml:

app:
  birthdays:
    - name: John
      date: 12/12/1980
    - name: Jack
      date: 19/08/1980

For this i have such a POJO:

public class Person {
    private String name;
    private String date;
}

this config mapping class:

@ConfigMapping(prefix = "app")
public interface BirthdayConfig {
    @WithConverter(PersonConverter.class)
    List<Person> birthdays();
}

And a PersonConverter class which is now just printing the incoming string.
The problem is the string coming as:

{"birthdays": [{"name": "John"

Is this a bug or i doing something wrong?

Sorry for the late reply. I've missed this.

You don't need a Converter for this. A Converter is only suited to convert single-element values, not composed elements.

Composed elements are handled automatically, so you need to define your mapping as follows:

@ConfigMapping(prefix = "app")
public interface BirthdayConfig {
    List<Person> birthdays();

    interface Person {
        String name();
        String date();
    }
}

And it will work out of the box.
