为动态json密钥编写java DTO的最佳方式是什么？

import com.fasterxml.jackson.annotation.JsonAnySetter;
import com.fasterxml.jackson.databind.ObjectMapper;

import java.util.HashMap;
import java.util.Map;

public class DynamicDto {
    private Map<String, Object> properties = new HashMap<>();

    @JsonAnySetter
    public void setProperty(String key, Object value) {
        properties.put(key, value);
    }

    public Map<String, Object> getProperties() {
        return properties;
    }

    public static void main(String[] args) throws Exception {
        String json = "{\"name\": \"John\", \"age\": 30, \"city\": \"New York\"}";

        ObjectMapper objectMapper = new ObjectMapper();
        DynamicDto dto = objectMapper.readValue(json, DynamicDto.class);

        System.out.println(dto.getProperties());
    }
}
