如何使用杰克逊API重命名JsonNode中的字段 [英] how to rename a field in a JsonNode using jackson API

问题描述

我有一个带有此JSON的JsonNode:

I have a JsonNode with this JSON in it :

{"temperature":17,"long":200,"lat":100}

我想将JsonNode更改为这样

I want to change the JsonNode to look like this

{"MyNewFieldName":17,"long":200,"lat":100}

是否可以使用Jackson API?

Is it possible using Jackson API ?

推荐答案

您将无法重命名键值JSON对中的键.您需要做的是创建一个具有相同值但具有不同键的新键值对，并删除旧的键值对.

You won't be able to rename keys in key-value JSON pairs. What you will need to do is create a new key-value pair with the same value but with a different key and remove the old one.

JsonNode node = ...;
ObjectNode object = (ObjectNode) node;
object.set("MyNewFieldName", node.get("temperature"));
object.remove("temperature");
