Java 显示所需的json dto类

创建了一个dto类，通过服务jsonschema2pojo.org/处理json。 结果是一个包含其他类的类，例如：

public  class GeneralExmp{
 private Strig name;
 // GetAndSet
  public class Exmp2{
 private Strig id;
private Map<String, Object> additionalProperties = new HashMap<String, Object>();
// GetAndSet

}
 public class Exmp3{
 private Strig val;
private Map<String, Object> additionalProperties = new HashMap<String, Object>();
// GetAndSet

}
}

json获得的类：

@Service
public class InstrumentGetService {
    RestTemplate restTemlate;
        
        public List<Params> getInfo(String token,
                 String order) {
            final var url = String.format(
                    "https://example.ru/rest/getOrderStatus.do?token=%s&orderId=%s", token, order);
            GeneralExmp dto = restTemlate.getForObject(url, GeneralExmp.class);
            return Collections.singletonList(toModel(dto));
        }

告诉我如何正确实现toModel方法？我无法将get和set从Exmp类获取到Params构造函数中

@Service
public class InstrumentGetService {
    RestTemplate restTemlate;
        
        public List<Params> getInfo(String token,
                 String order) {
            final var url = String.format(
                    "https://example.ru/rest/getOrderStatus.do?token=%s&orderId=%s", token, order);
            GeneralExmp dto = restTemlate.getForObject(url, GeneralExmp.class);
            return Collections.singletonList(toModel(dto));
        }

public Params toModel(GeneralExmp dto) {
            //??
            
            return new Params(//? , //?);
        }
