I am working on a JavaSE application in which I would like to connect to a Spring-MVC based server to get List of objects, Objects itself. I looked up on net, and came upon JSON. While I agree that it is working, but it is very inefficient as I have to go through the 2 while loops and seems not so sophisticated. For this reason I researched and found out I can use Spring remoting to achieve the task.
One thing I would like to do is to send over objects directly, instead of converting them by JSON, and sending.
I am pasting my code below for what I have with JSON, I would appreciate if I know this seems more better or is Spring remoting more sophisticated in long term too. A replacement code for the client side would be nice. Thanks.
Client code :
public void getCanvas(){
JsonFactory jsonFactory = new JsonFactory();
String canvas = "";
try {
JsonParser jsonParser = jsonFactory.createJsonParser(new URL(canvasURL));
JsonToken token = jsonParser.nextToken();
while (token!=JsonToken.START_ARRAY && token!=null){
token = jsonParser.nextToken();
if(token==null){break;}
System.out.println("Token is "+jsonParser.getText());
}
while (token!=JsonToken.END_ARRAY){
token = jsonParser.nextToken();
if(token == JsonToken.START_OBJECT){
canvas = jsonParser.toString();
System.out.println("Canvas is "+canvas);
}
}
} catch (IOException e) {
e.printStackTrace();
}
System.out.println("Canvas is "+canvas);
}
Server code :
@RequestMapping(value = "/getcanvas",method = RequestMethod.GET)
public @ResponseBody String getCanvasforFX(){
System.out.println("Canvas was requested");
Canvas canvas = this.canvasService.getCanvasById(10650);
canvas.setCanvasimage(null);
ObjectMapper objectMapper = new ObjectMapper();
try {
System.out.println("Canvas value is "+objectMapper.writeValueAsString(canvas));
return objectMapper.writeValueAsString(canvas);
} catch (IOException e) {
e.printStackTrace();
return null;
}
}
In the client-code I am getting the information, but again I have to read the fields, set them in object and update the UI, even though I am programming the server also, I want to directly receive an object, and cut out the middle-man(JSON). Thanks.
