Я получаю следующую ошибку при попытке получить доступ к API REST и получить ответ JSON, используя RestTemplate.
Ошибка:
Can not construct instance of io.sample.clover.client.domain.BusinessOrder$Customer: no suitable constructor found, can not deserialize from Object value.
(through reference chain: io.sample.clover.client.domain.BusinessOrder["customers"]->io.sample.clover.client.domain.BusinessOrder$Customers["elements"]->java.util.ArrayList[0])
Фрагмент кода:
public BusinessOrder getOrderById(String businessId,String orderId) {
RestTemplate restTemplate = new RestTemplate();
HttpHeaders requestHeaders = new HttpHeaders();
requestHeaders.add("Content-Type", "application/json");
requestHeaders.add("Authorization", "xxxxxxx");
HttpEntity entity = new HttpEntity(requestHeaders);
ResponseEntity<BusinessOrder> response = restTemplate.exchange(cloverApiBaseUrl + "merchants/"+businessId+"/orders/"+orderId+"?expand=lineItems&expand=payments&expand=customers", HttpMethod.GET, entity, BusinessOrder.class);
return response.getBody();
}
Класс модели BusinessOrder:
public class BusinessOrder {
private String id;
private String currency;
private Customers customers;
private Employee employee;
private int total;
private String title;
private String note;
private boolean taxRemoved;
private boolean isVat;
private String state;
private boolean manualTransaction;
private boolean groupLineItems;
private boolean testMode;
private String payType;
private String createdTime;
private String modifiedTime;
private LineItems lineItems;
private Payments payments;
@JsonIgnoreProperties(ignoreUnknown = true)
public BusinessOrder() {
}
public class Customers {
private List<Customer> elements;
@JsonGetter("elements")
public List<Customer> getElements() {
return elements;
}
}
public class LineItems {
private List<LineItem> elements;
@JsonGetter("elements")
public List<LineItem> getElements() {
return elements;
}
}
public class Payments {
private List<Payment> elements;
@JsonGetter("elements")
public List<Payment> getElements() {
return elements;
}

public class Employee {

public class LineItem {

private int tipAmount;
private int taxAmount;

private int createdTime;
private int modifiedTime;
private boolean offline;
private String result;
public class Order {
private String id;
}
public class Device {

public class Tender {

public class Customer {
private String id;
private OrderRef orderRef;
private String firstName;

public class OrderRef {

}
}
}
Внутри этого класса модели BusinessOrder существуют другие классы модели.включены как внутренние классы.Каждый идентификатор класса имеет конструктор по умолчанию и соответствующие методы getter и setter.
Ответ json, который нужно отобразить с помощью схемы pojo, может быть показан следующим образом:
{
"id": "xxxxx",
"currency": "USD",
