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");    private Integer id;   private String name;    private WorkOrderType(Integer id, String name) {     this.id = id;     this.name = name;   }    //Setters, getters.... } 

I return enum array with my controller ( new OrderType[] {UNKNOWN,TYPEA,TYPEB,TYPEC};), and Spring serializes it into the following json string:

["UNKNOWN", "TYPEA", "TYPEB", "TYPEC"]  

What is the best approach to force Jackson to serialize enums just like POJOs? E.g.:

[   {"id": 1, "name": "Undefined"},   {"id": 2, "name": "Type A"},   {"id": 3, "name": "Type B"},   {"id": 4, "name": "Type C"} ] 

I played with different annotations but couldn't manage to get such result.

Finally I found solution myself.

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

public class OrderTypeSerializer extends JsonSerializer<OrderType> {    @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();   } }
