JSON属性的简单的自定义映射对象属性与改造 [英] Simple custom mapping of JSON property to object property with Retrofit

问题描述

什么是定义在改造特定对象属性JSON属性的自定义映射关系最简单的方法？

What is the simplest way to define a custom mapping of a JSON property to a particular object property in RetroFit?

一组奖励的例子JSON响应：

Example JSON response for a set of "rewards":

[
  {
    "name" : "$5 Voucher",
    "description" : "Get $5 off your next purchase",
    "assets" : {
      "icon" : "icon.png"
    }
  }
]

在我的Andr​​oid项目奖励类：

Reward class in my Android project:

public class Reward {
  @SerializedName("name")
  private String name;

  @SerializedName("description")
  private String description;

  @SerializedName("icon")
  private String icon;
}

由于名称和说明图1：1的服务器响应，改造具有执行映射没有问题，但偶像为null，因为我没有映射 assets.icon的自定义路径方式到图标。

Because name and description map 1:1 with the server response, RetroFit has no issues performing the mapping, but "icon" is null because I have no way of mapping the custom path of assets.icon to icon.

在 RestKit 库的iOS，一个基本特点是定义的自定义对象映射，它可以让您轻松与一些键/值对定义这些映射。是否任何类似的改造存在吗？每一个解决方案，我看似乎涉及了很多额外的code制作定制的转换器。有没有更简单的方法？

In the RestKit library for iOS, a fundamental feature is defining custom object mapping, which allows you to easily define these mappings with some key/value pairs. Does anything similar exist in RetroFit? Every solution I see seems to involve a lot of extra code for making custom converters. Is there no easier way?

推荐答案

试试这个：

class Reward {
    String name;
    String description;
    Asset assets;

    class Asset {
        String icon;
    }
}
