我得到的是json响应，我必须用Java构造此响应并传递给其他人api，我是json的新手，请帮助我

Answer 1

看看Jackson，这是一个很好的教程供您遵循：https://www.baeldung.com/jackson-object-mapper-tutorial

Answer 2

Java没有用于解析和存储JSON对象的任何内置方法。您可以使用Google的第三方库GSON或JSONParser来以Java处理JSON。

1. 从Google下载并配置SimpleJson。
2. 导入下载的软件包。

3. 然后使用以下代码来解析JSON：

   JSONParser解析器=新的JSONParser（）;

   JSONObject json =（JSONObject）parser.parse（stringToParse）;

json是您的JSON对象。
