geojson coordinate conversion to the format of the data coming from PostgreSQL?

[المشرف العام]

I use hibernate spatial and geotools

this is save to vector code :

if (vectorType.equalsIgnoreCase("Point")) { LineString point =new GeometryJSON().readPoint(item.getData()); lineString.setSRID(3857); theEvent.setGeom1(lineString); theEvent.setVectorType(vectorType); }after I want to read data from the database format geojson but I need to do the shortcut

I did the following code :

if(entity.getVectorType().trim().equalsIgnoreCase("Point")) { JSONObject point = new JSONObject(); point.put("type", "Point"); JSONArray coord = new JSONArray("["+entity.getGeom().getX()+","+entity.getGeom().getY()+"]"); point.put("coordinates", coord); geoJson.setData(point.toString()); }but I must do shortcut . how can I do. I think do with geotools. we can use FeatureJson but how ?

like this : {"coordinates":[31.253906786442,26.859375536442],"type":"Point"}

Do you any ideaa ?
