Gson反序列化Map& K，V& gt;由WCF Rest服务序列化 [英] Gson deserialize Map<K,V> serialized by WCF Rest service

问题描述

我有WCF休息服务。我想在Android设备上使用它。为此，我选择了gson库。在我想从我的服务包含对象的地图返回之前，一切似乎都工作正常。 Gson将其序列化（并且我假设还会尝试反序列化），例如：

I have a WCF Rest Service. I would like to use it from Android device. To do this I have chosen gson library. Everything seemed to work fine until I wanted to return from my service Object Containing Map. Gson serializes it (and as I am assuming also tries to deserialize from it) as something like:

{"org.Mob.ComplexObject@3dac2f9c":"TAX1","org.Mob.ComplexObject@7369ca65":"TAX2"}

但是我的服务发送的json看起来像：

But the json sent by my service looks like:

{"Key":
    {"DefaultValue":"True",
     "Description":null,
     "DisplayName":"Custom Boolean",
     "FieldType":0,
     "Id":6,
     "IsReadOnly":false,
     "IsRequired":false,
     "MaxLength":null,
     "Name":"BoolVal",
     "ParamType":0},
 "Value":"True"},
{"Key":
    {"DefaultValue":"",
     "Description":null,
     "DisplayName":"Custom Text",
     "FieldType":4,
     "Id":7,
     "IsReadOnly":false,
     "IsRequired":true,
     "MaxLength":16,
     "Name":"TextVal",
     "ParamType":0},
 "Value":"sda"}
}

推荐答案

另一种方法是添加您自己的Map / Dictionary实现，该实现扩展了ArrayList，实际上是一个KVPair列表，其中KVPair如下：

The other way to do it could be adding you own implementation of Map / Dictionary which extends ArrayList, and in fact is a List of KVPair, where KVPair looks like:

class KVPair<K,V>{
    K Key;
    V Value;
}

我不知道它是否优雅，但在我的情况下有效。

I don't know if it's elegant, but it worked in my case.
