如何使用JSON-B反序列化未知属性？

public class MyData {
    private String knownProperty;

    // Getter and Setter for knownProperty

    // Handle unknown properties
    @JsonbProperty(nillable = true)
    private Map<String, JsonValue> unknownProperties;

    // Getter and Setter for unknownProperties
}

import javax.json.bind.Jsonb;
import javax.json.bind.JsonbBuilder;

public class Main {
    public static void main(String[] args) {
        String json = "{\"knownProperty\":\"value\",\"unknownProperty\":\"value\"}";

        Jsonb jsonb = JsonbBuilder.create();
        MyData myData = jsonb.fromJson(json, MyData.class);

        System.out.println(myData.getKnownProperty()); // Output: value
        System.out.println(myData.getUnknownProperties()); // Output: {unknownProperty=value}
    }
}
