#C++ class to json
##概述
从idl中生成C++ class，而C++ class支持jsoncpp的tojson与fromjson操作，从而实现自动化json序列化与反序列化C++结构体的目的。
##例子
###idl定义
idl保存到in.h中
#include
#include
#include
#include
#include
#include
//京东库存服务的IDL
namespace jd{
namespace core{
namespace stock{
class CLockInventoryForPaiPaiReq{
//商品id
std::string productId;
};
class CLockInventoryForPaiPaiResp{
//结果
int32_t retCode;
};
}
}
}
###自动生成
./fishjson < in.h > out.h
###生成结果
