本文是基本上一篇博文进行改进而成，上一篇请见：

此处就不多说了，直接上代码。

1. 序列化基类

 

#pragma once#include 
    
     #include 
     
      #include "json/json.h"using std::string;using std::vector;struct CJsonObejectBase{protected:	enum CEnumJsonTypeMap	{		asArray = 1,	//是数组		asJsonObj,		//是复杂对象		asBool,		asInt,		asUInt,		asString,		asInt64,		asUInt64,	};public:	CJsonObejectBase(void){}public:	virtual ~CJsonObejectBase(void){}		string Serialize()	{		Json::Value new_item = DoSerialize();				Json::FastWriter writer;  		std::string out2 = writer.write(new_item); 		return out2;	}		bool DeSerialize(const char* str)	{		Json::Reader reader;  		Json::Value root;		if (reader.parse(str, root))		{  			return DoDeSerialize(root);		}		return false;	}protected:	bool DoDeSerialize(Json::Value& root)	{		int nSize = m_listName.size();		for (int i=0; i < nSize; ++i )		{			void* pAddr = m_listPropertyAddr[i];			switch(m_listType[i])			{			case asJsonObj:				{					if (!root[ m_listName[i] ].isNull()) 						((CJsonObejectBase*)pAddr)->DoDeSerialize(root[m_listName[i]]);				}								break;			case asBool:				(*(bool*)pAddr) = root.get(m_listName[i], 0).asBool();				break;			case asInt:				(*(INT*)pAddr) = root.get(m_listName[i], 0).asInt();				break;			case asUInt:				(*(UINT*)pAddr) = root.get(m_listName[i], 0).asUInt();				break;			case asInt64:				(*(LONGLONG*)pAddr) = root.get(m_listName[i], 0).asInt64();				break;			case asUInt64:				(*(ULONGLONG*)pAddr) = root.get(m_listName[i], 0).asUInt64();				break;			case asString:				(*(string*)pAddr) = root.get(m_listName[i], "").asString();			default:				//我暂时只支持这几种类型，需要的可以自行添加 				break;			}					}		return true;	}	Json::Value DoSerialize()	{		Json::Value new_item;		int nSize = m_listName.size();		for (int i=0; i < nSize; ++i )		{			void* pAddr = m_listPropertyAddr[i];			switch(m_listType[i])			{			case asArray:				break;			case asJsonObj:				new_item[m_listName[i]] = ((CJsonObejectBase*)pAddr)->DoSerialize();				break;			case asBool:				new_item[m_listName[i]] = (*(bool*)pAddr);			case asInt:				new_item[m_listName[i]] = (*(INT*)pAddr);				break;			case asUInt:				new_item[m_listName[i]] = (*(UINT*)pAddr);				break;			case asInt64:				new_item[m_listName[i]] = (*(LONGLONG*)pAddr);				break;			case asUInt64:				new_item[m_listName[i]] = (*(ULONGLONG*)pAddr);				break;			case asString:				new_item[m_listName[i]] = (*(string*)pAddr);			default:				//我暂时只支持这几种类型，需要的可以自行添加 				break;			}				}		return new_item;	}	void SetProperty(string name, CEnumJsonTypeMap type, void* addr)	{		m_listName.push_back(name);		m_listPropertyAddr.push_back(addr);		m_listType.push_back(type);	}	virtual void SetPropertys() = 0;private:	vector
      
        m_listName;	vector
       
          m_listPropertyAddr;	vector
        
         	   m_listType;};
        
       
      
     
    

2.测试的派生类

 

 

struct CSubTestStruct : public CJsonObejectBase{	CSubTestStruct()	{		SubMsgID = 0;		SetPropertys();	}	ULONGLONG SubMsgID;	string SubMsgTitle;protected:	//子类需要实现此函数，并且将相应的映射关系进行设置 	virtual void SetPropertys()	{		SetProperty("SubMsgID", asUInt64, &SubMsgID);		SetProperty("SubMsgTitle", asString, &SubMsgTitle);	}};struct CTestStruct : public CJsonObejectBase{	CTestStruct()	{		SetPropertys();	}	ULONGLONG MsgID;	string MsgTitle;	string MsgContent;	CSubTestStruct subObj;protected:	//子类需要实现此函数，并且将相应的映射关系进行设置 	virtual void SetPropertys()	{		SetProperty("MsgID", asUInt64, &MsgID);		SetProperty("MsgTitle", asString, &MsgTitle);		SetProperty("MsgContent", asString, &MsgContent);		SetProperty("subObj", asJsonObj, &subObj);	}};

注意，此处CSubTestStruct类型的对象是CTestStruct的一个成员.

3.测试代码及效果图

 

1). 序列化

 

void CJasonSerializeDlg::OnBnClickedOk(){	CTestStruct stru;	stru.MsgID = 11223344;	stru.MsgTitle = "黑黑";	stru.MsgContent = "哈哈";	CString strTest = stru.Serialize().c_str();	AfxMessageBox(strTest);}

效果

 

2). 反序列化

 

void CJasonSerializeDlg::OnBnClickedOk2(){	const char* pstr = "{\"MsgContent\":\"哈哈22\",\"MsgID\":11111,\"MsgTitle\":\"黑黑22\",\"subObj\":{\"SubMsgID\":3333,\"SubMsgTitle\":\"子内容\"}}";	CTestStruct stru;	stru.DeSerialize(pstr);	CString strShow = "";	strShow.Format("MsgID:%I64u\r\nMsgTile:%s\r\nMsgContent:%s\r\nSubMsgTitle:%s", stru.MsgID, stru.MsgTitle.c_str(), stru.MsgContent.c_str(), stru.subObj.SubMsgTitle.c_str());	AfxMessageBox(strShow);}

效果

 

4. 接下来要解决的问题

当对象中存在数组或者列表时，我暂时还没想到好的办法处理，如果哪位有思路，还请赐教；如果对于此类序列化与反序列化有好的方法，也请指教！
