Gson字符串类的自定义反序列化程序

import com.google.gson.*;

public class CustomDeserializer implements JsonDeserializer<CustomObject> {
    @Override
    public CustomObject deserialize(JsonElement json, Type typeOfT, JsonDeserializationContext context) throws JsonParseException {
        JsonObject jsonObject = json.getAsJsonObject();
        
        // 解析JSON字段并创建CustomObject对象
        String field1 = jsonObject.get("field1").getAsString();
        int field2 = jsonObject.get("field2").getAsInt();
        boolean field3 = jsonObject.get("field3").getAsBoolean();
        
        CustomObject customObject = new CustomObject(field1, field2, field3);
        
        return customObject;
    }

Gson gson = new GsonBuilder()
        .registerTypeAdapter(CustomObject.class, new CustomDeserializer())
        .create();
        
CustomObject customObject = gson.fromJson(jsonString, CustomObject.class);
