Jackson Generics with variable JsonProperty (usage with generics)

Question

I have class that looks like this:

public class Data {

    @JsonProperty(\"difficulties\")
    private U[] data;

    // ... geter setter construct         


        

Answer 1

You can use @JsonAnyGetter annotation.

public class Data {

    @JsonIgnore
    private U[] data;

    @JsonIgnore
    private String propertyName;

    public Data(String propertyName) {
        this.propertyName = propertyName;
    }

    // ... geter setter

    @JsonAnyGetter
    public Map any() {
        return Collections.singletonMap(propertyName, data);
    }
}

And use it like below:

Data difficulties = new Data<>("difficulties");

write whatever you want instead of "difficulties" string. Set your list to Data generic class instead of Difficulties object if you want
