GSON。将整数反序列化为整数而不是双精度 [英] Gson. Deserialize integers as integers and not as doubles

问题描述

我在里面有任意的json对象。我想在一个Map中反序列化它。除了将整数转换为双打之外，一切都可以。请参阅示例：

pre $ {code> {id：1，inner_obj：{key：value，num ：666，map：{key：value}}}

对此进行反序列化（map.toString（））：

  {id = 1.0，inner_obj = {key = value，num = 666.0，map = {key = value}}} 
  

是否有反序列化id和num作为整数而不是双精度？

解决方案

JSON中没有整数类型。 1和1.0是一样的。你需要在代码中解析1.0到1。或者您需要将JSON映射到某个VO类，并明确定义类的字段类型，以便GSON可以理解您要查找的内容。

I have json object with arbitary values inside. And I want to deserialize it in a Map. Everything is ok except converting integers to a doubles. See example:

{"id":1, "inner_obj":{"key":"value","num":666,"map":{"key":"value"}}}

deserializes to this(map.toString()):

{id=1.0, inner_obj={key=value, num=666.0, map={key=value}}}

Is there some easy way to deserialize "id" and "num" as Integers and not as Doubles?

解决方案

There are no integer type in JSON. 1 and 1.0 are the same. You need to parse that 1.0 to 1 in your code. Or you need to map the JSON to some VO class and define the type of fields of the class explicitly , so that GSON can understand what you are looking for.
