}

1. we can see that 6 classes is needed for this JSON
2. Therefore, 6 models are needed

Key Things to note in this workshop

• All variables need to follow the Json file naming

BoardGameController

1. The controller used

@RestController

For Json it is using rest controller not purely controller 2. The request mapping

@RequestMapping(path="/api/boardgame", consumes = MediaType.APPLICATION_JSON_VALUE, produces=MediaType.APPLICATION_JSON_VALUE)

For Json, in the request mapping there is consume and produce 3. This part will fufil GET /api/boardgame/

@GetMapping(path="{msId}")

Models

• all need to have getter and setter for all variables

DecodingBoard

1. DecodingBoard only has total_count var therefore only 1 variable 2.Need to convert it to a Json Object using the following code

public JsonObjectBuilder toJSON(){
        return Json.createObjectBuilder()
                .add("totalCount", this.getTotal_count());
    }

Mastermind

1. Mastermind has 6 variables
2. insertCount and updateCount is needed as stated in the workshop 3.isUpSert is based on task 3

Pegs

1. Pegs has total_count var and types obj
2. total_count needs to be converted to JsOn obj
3. types needs to be converted to Json obj
4. Code

public JsonObjectBuilder toJSON(){
        JsonArrayBuilder arrbld = Json.createArrayBuilder();
        List<JsonObjectBuilder> listOfTypes = this.getTypes()
                            .stream()
                            .map(t -> t.toJSON())
                            .toList();
        for (JsonObjectBuilder x : listOfTypes)
            arrbld.add(x);

        return Json.createObjectBuilder()
                .add("total_count", this.getTotal_count())
                .add("types", arrbld);

Pieces

1. Pieces have 4 obj decoding_board, pegs and rulebook
2. All need to be converted to Json Obj
3. Code

public JsonObjectBuilder toJSON(){
        return Json.createObjectBuilder()
                .add("decoding_board", this.getDecoding_board().toJSON())
                .add("pegs", this.getPegs().toJSON())
                .add("rulebook", this.getRulebook().toJSON());      
    }

Rulebook

1. Rulebook has total_count var and file obj
2. All need to be converted to Json Obj
3. Code

public JsonObjectBuilder toJSON(){
        return Json.createObjectBuilder()
                .add("total_count", this.getTotal_count())
                .add("file", this.getFile());
    } 

Type

1. Types have 2 var type and count
2. Both need to be converted to Json Obj
3. Code

public JsonObjectBuilder toJSON(){
        return Json.createObjectBuilder()
                .add("type", this.getType())
                .add("count", this.getCount());
                
    } 

BoardGameService

1. This is a service hence @Service is needed
2. KIV on what is a service
