java - 如何使用 Google 的 GSON 解析 JSON 无效标识符？

Question

我有一个返回 JSON 的 REST Web 服务。作为示例，我有以下响应:

现在我想使用 GSON 将其转换为 POJO 对象。对于顶部根节点，我创建了以下类:

public class JSONContainer {

    ArrayList<JSONWorkItem> items = new ArrayList<JSONWorkItem>();

    public ArrayList<JSONWorkItem> getItems() {
        return items;
    }

}

这不起作用，因为我认为 ArrayList 应该名为 oslc_cm:results，但我不能，因为这不是有效的 Java 标识符。那我能做什么呢？

Answer 1

答案可以在 Gson User Guide 中找到。 。您可以使用注释 SerializedName 来实现此目的。

所以 POJO 类应该如下所示:

public class JSONContainer {

    @SerializedName("oslc_cm:results")
    ArrayList<JSONWorkItem> items = new ArrayList<JSONWorkItem>();

    public ArrayList<JSONWorkItem> getItems() {
        return items;
    }

}
