从各种 JSON 路径创建 JSON 对象

我们需要从提供的各种 JSONPaths 创建 JSON 对象。例如，下面是要创建的新 JSON 对象中的两个路径以及该路径的值。

$.student.firstName = "Abc"
$.student.subject['physics'].mark=100

是否有任何java开源库可以帮助仅从该路径创建结果对象？

{
 "student":{
 "firstName":"Abc",
 "physics":{
   "mark":100
  }
 }
}

我们探索了某些库，例如JSONPath https://github.com/json-path/JsonPath。它可以选择解析 JSON 文件，但不能选择从路径递归创建 JSON 文件。

总部设在这把叉子 https://github.com/KumarJayanti/JsonPath from JsonPath https://github.com/json-path/JsonPath添加从 json 路径创建新 json 节点的功能，您可以执行以下操作：

//    columnsMap = key: jsonPath node, value: value to be added to node

String json = "{ }";
for (Entry<String, String> entry : columnsMap.entrySet()) {
  JsonPath compiledPath = JsonPath.compile(entry.getKey());
  Object parsedJsonPath =
      compiledPath.set(configuration.jsonProvider().parse(json), entry.getValue(), configuration);
  json = JsonPath.parse(parsedJsonPath).jsonString();
}
return json;

输入（列映射）：

{vendor_account_ids=1234567,4567123,789785,
 charges[0].vendor_charge_id=CHARGE-01,
 charges[1].vendor_charge_id=CHARGE-02,
 charges[0].type=LOAN_DEDUCTION,
 charges[0].conditions.alternative_delivery_date=false,
 charges[0].conditions.depends_on_vendor_charge_ids[0]=ID01,
 charges[0].conditions.depends_on_vendor_charge_ids[1]=ID02,
 charges[0].conditions.order_total.maximum_value=123.45,
 charges[0].conditions.payment_method=BANK_SLIP,
 charges[0].conditions.scaled_from=ORDER_TOTAL,
 charges[0].conditions.product_attributes.is_alcoholic=false,
 charges[0].conditions.payment_terms[0]=1,
 charges[0].conditions.payment_terms[1]=30,
 charges[0].output.scope=LINE_ITEM,
 charges[0].output.apply_to=DISCOUNT_AMOUNT,
 charges[0].output.type=PERCENT,
 charges[0].output.ratio=FIXED,
 charges[0].output.ranges[0].from=1,
 charges[0].output.ranges[0].value=10,
 charges[0].output.vendor_item_ids[0]=SKU001,
 charges[0].output.vendor_item_ids[1]=SKU002
}
