我已经有了一个.NET Web服务休息而以JSON提供响应。我消耗在Java的web服务。我用GSON序列化和从JSON。

I've got a .NET Rest webservice which delivers responses in Json. I consume the webservice in Java. I use Gson to serialize to and from Json.

我有.NET和Java之间序列化，当涉及到多态的问题。

I've got problems serializing between .NET and Java when it comes to polymorphism.

我已经照着为了写一个自定义的串行适配器GSON我的类继承抽象类本指南： http://www.java codegeeks.com / 2012/04 / JSON-与-GSON和 - 抽象classes.html

I've followed this guide in order to write a custom serializer adapter for Gson for my classes that extends an abstract class: http://www.javacodegeeks.com/2012/04/json-with-gson-and-abstract-classes.html

的问题是，GSON然后生成以下内容：

The problem is that Gson then generates the following:

{"type":"Circle","properties":{"color":"red"}}

在.NET中的默认实现不理解新的属性属性。我需要写的适配器如下：

The default implementation in .NET does not understand the new "properties" attribute. What I need the adapter to write is the following:

{"__type":"Circle","color":"red"}

如何更改适配器输出这一序列，而不是和谁反序列化时也？

How do I change the adapter to output this instead when serializing and who to deserialize it too?

推荐答案

中加入以下的抽象基类，所以它会自动通过GSON系列化解决了：

Solved it by adding the following to the abstract base class so it's automatically serialized by Gson:

private String __type = this.getClass().getSimpleName();
