How to structure Multiple object and array of JSON in java in beanshell and review the output

问题

This is JSON file. I want make java can produce like this json. Just ignore the value, What i want is the structure of the json. I am creating it in the beanshell sampler

This i have tried in the beanshell sampler

"itemLines": {
    "itemLine": [
        {
            "bundleParentId": "",
            "id": "1",
            "itemType": "ART",
            "itemNo": "00258882",
            "requiredQty": "1",
            "unitOfMeasure": "Piece"
        },{
            "bundleParentId": "",
            "id": "2",
            "itemType": "ART",
            "itemNo": "20215877",
            "requiredQty": "1",
            "unitOfMeasure": "Piece"
        },
        {
            "bundleParentId": "",
            "id": "2",
            "itemType": "ART",
            "itemNo": "20215877",
            "requiredQty": "1",
            "unitOfMeasure": "Piece"
        }
    ]
}

The tried code is :

public void createJsonStructure() {

try
{
    JSONObject rootObject = new JSONObject();
    JSONArray articleArr = new JSONArray();
    String[] article_list = {"00258882", "70234185", "00258882"};
    log.info(article_list.length);  
    for (i=0;i<=article_list.length;i++)
    {
    JSONObject article_list= new JSONObject();
    article_list.put("id", "i+1");
    article_list.put("itemNo",article_list[i]);
    article_list.put("requiredQty", "1");
    articleArr.put(article_list);
    }
   log.info(articleArr);        
    rootObject.put("itemLines", articleArr);
    log.info("rootObject is"+rootObject.toString(4));
    props.put("JsonObjectoutput", rootObject.toString(4));        
   }
catch (Exception ex)
{
    ex.printStackTrace();
    log.info("notes");
}

}

The output is not pasted in the beanshell sampler

You can create object structure to look like your json and than use Gson to serialize you objects int json.

Example (i used lombok to remove bulk code):

import lombok.AllArgsConstructor;
import lombok.Data;

@Data
@AllArgsConstructor
public class Item {

    private String bundleParentId;
    private int id;
    private String itemType;
    private String itemNo;
    private int requiredQty;
    private String unitOfMeasure;

}

import lombok.AllArgsConstructor;
import lombok.Data;

import java.util.List;

@Data
@AllArgsConstructor
public class ItemLine {

    private List<Item> itemLine;

}

import lombok.AllArgsConstructor;
import lombok.Data;

@Data
@AllArgsConstructor
public class ItemLines {

    private ItemLine itemLines;

}

import com.google.gson.Gson;
import com.google.gson.GsonBuilder;

import java.util.ArrayList;
import java.util.List;

public class JsonTest {

    public static void main(String[] args) {
        Item item1 = new Item("", 1,"ART", "00258882", 1, "Piece");
        Item item2 = new Item("", 2,"ART", "20215877", 1, "Piece");
        Item item3 = new Item("", 2,"ART", "20215877", 1, "Piece");

        List<Item> items = new ArrayList<>();
        items.add(item1);
        items.add(item2);
        items.add(item3);

        ItemLine itemLine = new ItemLine(items);
        ItemLines itemLines = new ItemLines(itemLine);

        Gson gson = new GsonBuilder().setPrettyPrinting().create();

        System.out.println(gson.toJson(itemLines));
    }

}
