How can i add an object to a Entity class without getting saved to DB.

How can i add an object to a Entity class without getting saved to DB.

Use the following annotations before the embedded object within the entity

@JsonInclude
@Transient
@Embedded

@Entity
public class MillingData {

   public MillingData() {
      super();
   }

   @Id
   @GeneratedValue
   private String id;

   private String name;

   private Float depth;

   @JsonInclude
   @Transient
   @Embedded
   private UnitData unitData;

Also use the annotation within the embedded object class definition

@Embeddable
public class UnitData {

    private String id;

    private Map map;

    public Map getMap() {
        return map;
    }

Hope this helps
