Sample of JSON String would look like this.
String
jsonText="{\"cartId\":\"31028\",\"userId\":\"106784\",\"attributes\":{\"count\":\"1\",\"amount\":\"10\",\"email\":\"N\",\"Test\":\"No\",\"phone\":\"N\"}}";
The JSON maps to a Cart class, which holds these attributes as a Map.
public class Cart {
private String cartId;
private String userId;
private Map<Attributes,String> attributes;
}
Attributes map to the Enum, as given below.
public enum Attributes {
Count(0),
Amount(1),
Email(2),
Phone(3);
private final int value;
private Attributes(int value) {
this.value = value;
}
public int getValue() {
return value;
}
public static Attributes findByValue(int value) {
switch (value) {
case 0:
return Count;
case 1:
return Amount;
case 2:
return Email;
case 3:
return Phone;
default:
return null;
}
}
}
Thanks!
