如何禁用从数字到字符串的Gson反序列化

import com.google.gson.*;

public class NumberToStringDeserializer implements JsonDeserializer<Number> {
    @Override
    public Number deserialize(JsonElement json, Type typeOfT, JsonDeserializationContext context) throws JsonParseException {
        if (json.isJsonPrimitive()) {
            JsonPrimitive jsonPrimitive = json.getAsJsonPrimitive();
            if (jsonPrimitive.isNumber()) {
                throw new JsonParseException("Cannot deserialize number as string");
            }
        }
        return json.getAsNumber();
    }
}

GsonBuilder gsonBuilder = new GsonBuilder();
gsonBuilder.registerTypeAdapter(Number.class, new NumberToStringDeserializer());
Gson gson = gsonBuilder.create();
