标题: c++ boost库 序列化与反序列化
1、定义类/结构体序列化函数：
template <typename Archive>
void serialize(Archive& ar, TOrder & obj, const unsigned int version = SERIALIZATION_VERSION)
{
        ar & BOOST_SERIALIZATION_NVP(obj.Param)
                & BOOST_SERIALIZATION_NVP(obj.OrderRef)
                & BOOST_SERIALIZATION_NVP(obj.UserID);
}
BOOST_SERIALIZATION_SHARED_PTR(TStopProfitOrder);

2、save、load函数：

1. #ifndef STRUCT_SAVE_LOAD_H_
   
2. #define STRUCT_SAVE_LOAD_H_
   
3. //
   
4. #include <string>
   
5. #include <fstream>
   
6. //
   
7. #include "boost/archive/text_iarchive.hpp"
   
8. #include "boost/archive/text_oarchive.hpp"
   
9. #include "boost/archive/xml_iarchive.hpp"
   
10. #include "boost/archive/xml_oarchive.hpp"
    
11. #include "boost/serialization/base_object.hpp"
    
12. #include "boost/serialization/list.hpp"
    
13. #include "boost/serialization/map.hpp"
    
14. #include "boost/serialization/vector.hpp"
    
15. #include "boost/serialization/set.hpp"
    
16. #include "boost/serialization/string.hpp"
    
17. #include "boost/serialization/shared_ptr.hpp"
    
18. //
    
19. const unsigned int SERIALIZATION_VERSION = 1;
    
20. //保存结构体数据
    
21. template<typename TemplateStruct> int save(const TemplateStruct & templateStruct,const std::string &strFileName,const unsigned int version = SERIALIZATION_VERSION)
    
22. {
    
23.         try
    
24.         {
    
25.                 std::ofstream ofs(strFileName.c_str());
    
26.                 boost::archive::xml_oarchive oa(ofs);
    
27.                 oa << BOOST_SERIALIZATION_NVP(templateStruct);
    
28.         }
    
29.         catch (...)
    
30.         {
    
31.                 return -1;
    
32.         }
    
33.         return 0;
    
34. }
    
35. //从文件加载结构体数据
    
36. template<typename TemplateStruct> int load(TemplateStruct & templateStruct,const std::string &strFileName,const unsigned int version = SERIALIZATION_VERSION)
    
37. {
    
38.         try
    
39.         {
    
40.                 std::ifstream ifs(strFileName.c_str());
    
41.                 boost::archive::xml_iarchive ia(ifs);
    
42.                 ia >> BOOST_SERIALIZATION_NVP(templateStruct);
    
43.         }
    
44.         catch (...)
    
45.         {
    
46.                 return -1;
    
47.         }
    
48.         return 0;
    
49. }
    
50. //
    
51. #endif

复制代码

3、直接调用save(xxxxSet, szFileName) 即可序列化数据列表，load反之。
