@JsonIgnore on interface takes precedence over @JsonIgnore(false) on subclass #306
Description
I found that a getter annotated with @JsonIgnore(false) in the subclass does not override @JsonIgnore in the implemented interface, even though @JsonIgnore(false) in the subclass should logically take precedence over the interface-level ignore.
Minimal reproduction:
public class Person extends BasicPerson implements PersonInterface{
public Person(String name) {
super(name);
}
public static void main(String[] args) throws JsonProcessingException {
ObjectMapper objectMapper = new ObjectMapper();
Person demoObject = new Person("Maksym");
objectMapper.disable(SerializationFeature.FAIL_ON_EMPTY_BEANS);
String json = objectMapper.writeValueAsString(demoObject);
System.out.println(json);
}
}
abstract class BasicPerson {
protected String name;
public BasicPerson(String name) {
this.name = name;
}
@JsonIgnore(false)
public String getName() {
return name;
}
}
interface PersonInterface {
@JsonIgnore
String getName();
}Expected output:
{"name":"Maksym"}Current result:
{}Jackson version 2.19.2
Correct me if this behavior is apparent to others, but I believe that since a Java class can have only one superclass and can implement multiple interfaces, it makes sense that configuration from the subclass should take precedence over the interface.
