如何在没有中间toString的情况下直接将JSONObject转换为byteArray？

import com.fasterxml.jackson.databind.ObjectMapper;
import com.fasterxml.jackson.databind.ObjectWriter;

import java.io.ByteArrayOutputStream;
import java.io.IOException;

public class JSONObjectToByteArrayExample {
    public static void main(String[] args) {
        // 创建JSONObject对象
        JSONObject jsonObject = new JSONObject();
        jsonObject.put("key1", "value1");
        jsonObject.put("key2", "value2");

        // 使用Jackson库将JSONObject转换为byteArray
        ObjectMapper objectMapper = new ObjectMapper();
        ObjectWriter objectWriter = objectMapper.writer().withDefaultPrettyPrinter();
        ByteArrayOutputStream byteArrayOutputStream = new ByteArrayOutputStream();
        try {
            objectWriter.writeValue(byteArrayOutputStream, jsonObject);
        } catch (IOException e) {
            e.printStackTrace();
        }

        // 获取转换后的byteArray
        byte[] byteArray = byteArrayOutputStream.toByteArray();

        // 打印结果
        System.out.println("转换后的byteArray: " + byteArray);
    }
}
