Immutable JSON Data Transfer Objects

Create Jackson annotated classes with @JsonData and @JsonDataField. For example, replace the boilerplate heavy:

public class Message {
  
  private final long time;
  private final String text;

  @JsonConstructor
  public Message(@JsonProperty("time") long time, @JsonProperty("text")  String text){
    this.time = time;
    this.text = text;
  }
  
  
  @JsonProperty("time")
  public long getTime(){
    return time;
  }
  
  @JsonProperty("text")
  public String getText(){
    return text;
  }
}

with:

@JsonData class Message {

 @JsonDataField("time") long time
 @JsonDataField("text") String text

}

which also handles toString, hashCode and equals, if not implemented.
