Gson和抽象超类：反序列化问题

遵循Axxiss链接，此处遵循答案。必须提供自定义的序列化器/解串器。

public class AClassAdapter  implements JsonSerializer<A>, JsonDeserializer<A> {  @Override  public JsonElement serialize(A src, Type typeOfSrc, JsonSerializationContext context) {      JsonObject result = new JsonObject();      result.add("type", new JsonPrimitive(src.getClass().getSimpleName()));      result.add("properties", context.serialize(src, src.getClass()));       return result;  }  @Override  public A deserialize(JsonElement json, Type typeOfT, JsonDeserializationContext context)        throws JsonParseException {    JsonObject jsonObject = json.getAsJsonObject();    String type = jsonObject.get("type").getAsString();    JsonElement element = jsonObject.get("properties");    try {         String fullName = typeOfT.getTypeName();        String packageText = fullName.substring(0, fullName.lastIndexOf(".") + 1);        return context.deserialize(element, Class.forName(packageText + type));    } catch (ClassNotFoundException cnfe) {        throw new JsonParseException("Unknown element type: " + type, cnfe);    }  }}

然后进行序列化，如下所示：

GsonBuilder gson = new GsonBuilder();gson.registerTypeAdapter(A.class, new ATypeAdapter());String json = gson.create().toJson(list);

并给出json字符串，反序列化为：

GsonBuilder gson = new GsonBuilder();gson.registerTypeAdapter(A.class, new ATypeAdapter());return gson.create().fromJson(json, A[].class);
