Parse GML string to application/GML+XML mediaType using *.http.MediaType

[Ben_java]

Hi,

I am working on a spring+ hibernate + postgres application, In one of the tables I have a column called geom with the Geometry. So I have annotated that entity column with @JsonSerialize(using = JsonGeometrySerializer.class) So my geometrySerializer takes that geometry and creates a wkt string of the geometry and addes it to the json object output. Below that in the json I want to add the GML of the same geometry. I do that again by GMLWriter.write(geom) which will return a gml string in the JSON. But what I want to do is in the place of GML string I want to add the GML mediaType which is not a string, so that when the json is viewed in the browser the GML tags can be expanded/collapsed. I think this can be achieved by using org.springframework.http.MediaType and serialize the geometry? Is this correct. Can any one provide an example please?

@Entity
...
...
@JsonSerialize(using = JsonGeometrySerializer.class)
public Geometry getGeom() {
return geom;
}
...

public class JsonGeometrySerializer extends JsonSerializer<Geometry> {

@Override
public void serialize(Geometry geom, JsonGenerator gen,
SerializerProvider provider) throws IOException,
JsonProcessingException {
...
...

GeometryFactory gf = new GeometryFactory();

if (geom != null) {

geom = geom.getEnvelope();

String wkt = wWriter.write(geom);
String gml = gWriter.write(geom);

gen.writeStartObject();
gen.writeStringField("wkt", wkt);
gen.writeFieldName("gml");
gen.writeStartArray();
gen.writeObject(gml);
gen.writeEndArray();

gen.writeEndObject();

}

Or is there a way GML can be embedded inside JSON without making GML a string?
