Serializing enums with Jackson

Question

I have an Enum desrcibed below:

public enum OrderType {

  UNKNOWN(0, \"Undefined\"),
  TYPEA(1, \"Type A\"),
  TYPEB(2, \"Type B\"),
  TYPEC(3, \"Type C\");         


        

Answer 1

Finally I found solution myself.

I had to annotate enum with @JsonSerialize(using = OrderTypeSerializer.class) and implement custom serializer:

public class OrderTypeSerializer extends JsonSerializer {

  @Override
  public void serialize(OrderType value, JsonGenerator generator,
            SerializerProvider provider) throws IOException,
            JsonProcessingException {

    generator.writeStartObject();
    generator.writeFieldName("id");
    generator.writeNumber(value.getId());
    generator.writeFieldName("name");
    generator.writeString(value.getName());
    generator.writeEndObject();
  }
}
