java - json中多个不同的嵌套对象进行改造

Answer 1

可以解析同一级别的对象的不同命名。在一种方式中，可以定义@SerializedName(value="name1", alternate={"name2", "name3"}) String b;含义，定义对象的替代名称。但要小心这个对象需要有相同的数据。在您的情况下，它将在所有情况下解析"id"，"name"，因为 json 在所有情况下都包含这两个字段。

另一方面，当您想要解析所有字段时，最好使用自定义JsonDeserializer。您可以在此处找到如何为 GSON 库编写自己的反序列化器的示例：反序列化器

Answer 2

好吧，我做到了，这是我的解决方案。它有效。
