通过Retrofit和GSON将复杂的JSON映射为Java对象的正确方法 [英] Proper way to map complex JSON as a Java object with Retrofit and GSON

问题描述

如果从REST API获得的JSON对象具有以下结构：

  {
 
IsError：false，
 
结果：{key1：value，key2：value，...} 
 
 } 
  

应该组合两个不同的Java类（IsError和Result） 2016年10月06日更新：

正确使用Retrofit2在新问题中询问

$ b $如果你的所有服务都要用这个结构响应，那么我会实现一个通用类，它包含 IsError c $ c>和结果：

  public class Response< T> {
 private boolean IsError; 
私人T结果; 
 
 // getters 
} 
  

然后对于每项服务将不得不使用相应的类，例如响应< MyClass1> ，响应< MyClass2> 等作为调用<> 。

If the JSON Object I'm getting from the REST API has the following structure:

{

"IsError":false,

"Result":{ "key1":"value", "key2":"value", ... }

}

Should two different Java classes (IsError and Result) be composed or only one including both, as the expected Object in the Call<>?

Proper usage with Retrofit2 asked in a new question

解决方案

If all your services are going to respond with that structure, then I would implement a generic class that includes both IsError and Result:

public class Response<T> {
    private boolean IsError;
    private T Result;

    // getters
}

Then for each service you would have to use the corresponding classes, e.g. Response<MyClass1>, Response<MyClass2>, etc. as the expected object in the Call<>.
