@JsonProperty support for an array of property names

[tbeech]

Often times when developing against a data model that may change (whether third party API or your own application models) where backwards compatibility is needed it would be nice to use the builder pattern to support multiple properties that map to the same internal field.

@JsonDeserialize( builder = MyClass.MyClassBuilder.class )
public class MyClass {
      private final String propertyA;

      MyClass( String propertyA ) {
        this.propertyA = propertyA;
        this.propertyB = propertyB;
      }

      // The updated class and eventStatus represents the most current version of the
      // data model
      @JsonProperty( "eventStatus" )
      public getPropertyA() {
        return this.propertyA;
      }

      @JsonPojoBuilder
      public static class MyClassBuilder {
        String eventStatus = "Success";

        @JsonProperty( { "eventCode", "eventStatus" } )
        public MyClassBuilder withEventStatus( String eventStatus ) {
          this.eventStatus = eventStatus;
          return this;
        }
      }
}

Would @JsonAlias from 2.9 work?

FasterXML/jackson-annotations#116

Let me RTFM the docs for that annotation, but I would guess that it would do exactly what I’m looking for. Thank you!

@tbeech Np, hope it works out -- brief overview of 2.9 at:

and @JsonAlias is definitely something that was high on most-wanted list.
Alternative would have been to extend @JsonProperty just like you suggested.
