java如何将JSONObject用什么方法转成BigDecimal并将数据传给priceDataTable

截图中 465到467行之间的代码：

            JSONObject key = JSONObject.parseObject(o.toString());
            BigDecimal bd = new BigDecimal(String.valueOf(key));
            BigDecimal paymentPrice1 = (BigDecimal) key.get("paymentPrice");

修改如下可正确获取 paymentPrice1 的值：

            JSONObject key = ((JSONObject)o).getJSONObject("key");
            BigDecimal paymentPrice1 = key.getBigDecimal("paymentPrice");

JSONObject key = JSONObject.parseObject(o.toString());
// 先看一下 o.toString 是否是一个JSONObject 如果是一个JSON对象那么就课可以用这种方式进行转换。
// 如果不是那就需要看下其他的规则
String result = key.getString("某个属性");
// 获取到是否有某个属性对应的值，以及是否可以进行类型转换
BigDecimal bd = new BigDecimal(result);
BigDecimal paymentPrice1 = (BigDecimal) key.get("paymentPrice");

jsonObject.getBigDecimal()
