Having a lot of trouble figuring out what I'm doing wrong. Sadly I had it working at one point, but can't determine what I changed that broke it.
From what I understand this should be fully supported now.
Object in question:
@Document
public class Place {
public final static String URI = "/place";
@Id private String id;
private String name;
private String caption;
private GeoJsonPoint location;
public Place() {}
public Place(GeoJsonPoint geoJsonPoint) {
this.location = geoJsonPoint;
}
// Proper getters & setters clipped.
}
The call (My version of Spring Boot includes the extra x/y coords for some reason.)
{
"id": null,
"name": null,
"caption": null,
"location": {
"x": 41.988161,
"y": -87.6911499,
"type": "Point",
"coordinates": [
41.988161,
-87.6911499
]
}
}
The Pom (Maybe I have the wrong/clashing dependencies?)

FINALLY got this working.
Created a custom JsonDeserializer
public class GeoJsonDeserializer extends JsonDeserializer<GeoJsonPoint> {
private final static String GEOJSON_TYPE_POINT = "Point";
private final static String JSON_KEY_GEOJSON_TYPE = "type";
private final static String JSON_KEY_GEOJSON_COORDS = "coordinates";
@Override
public GeoJsonPoint deserialize(JsonParser jp, DeserializationContext ctxt) throws IOException {
final JsonNode tree = jp.getCodec().readTree(jp);
final String type = tree.get(JSON_KEY_GEOJSON_TYPE).asText();
final JsonNode coordsNode = tree.get(JSON_KEY_GEOJSON_COORDS);
double x = 0;
double y = 0;
if(GEOJSON_TYPE_POINT.equalsIgnoreCase(type)) {
x = coordsNode.get(0).asDouble();
y = coordsNode.get(1).asDouble();
}
else {
System.out.println(String.format("No logic present to deserialize %s ", tree.asText()));
}
final GeoJsonPoint point = new GeoJsonPoint(x, y);
return point;
}
}
Then I just specified the a converter on the property itself.
@JsonDeserialize(using = GeoJsonDeserializer.class)
private GeoJsonPoint location;
