在C++中,序列化庫和動態庫可以很好地集成在一起,以便在運行時動態加載和使用這些庫
首先,確保你已經安裝了Boost庫。如果沒有,請訪問Boost官網下載并安裝。
創建一個名為serialization_dynamic_lib
的文件夾,然后在該文件夾中創建兩個子文件夾:include
和src
。
在include
文件夾中創建一個名為my_class.h
的頭文件,內容如下:
#ifndef MY_CLASS_H
#define MY_CLASS_H
#include <boost/serialization/access.hpp>
#include <boost/serialization/nvp.hpp>
class MyClass {
public:
MyClass() = default;
MyClass(int x, int y) : x_(x), y_(y) {}
int getX() const { return x_; }
int getY() const { return y_; }
private:
friend class boost::serialization::access;
template<class Archive>
void serialize(Archive & ar, const unsigned int version) {
ar & BOOST_SERIALIZATION_NVP(x_);
ar & BOOST_SERIALIZATION_NVP(y_);
}
int x_;
int y_;
};
#endif // MY_CLASS_H
src
文件夾中創建一個名為my_class.cpp
的源文件,內容如下:#include "../include/my_class.h"
src
文件夾中創建一個名為CMakeLists.txt
的文件,內容如下:cmake_minimum_required(VERSION 3.0)
project(MyClassLibrary)
set(CMAKE_CXX_STANDARD 11)
find_package(Boost REQUIRED serialization)
add_library(my_class SHARED my_class.cpp)
target_include_directories(my_class PUBLIC ${CMAKE_CURRENT_SOURCE_DIR}/../include)
target_link_libraries(my_class PRIVATE Boost::serialization)
serialization_dynamic_lib
文件夾中創建一個名為build
的文件夾,然后進入該文件夾并運行以下命令:cmake ..
cmake --build .
這將生成一個名為my_class
的動態庫(在Windows上為my_class.dll
,在Linux上為libmy_class.so
)。
main_project
,并在其中創建一個名為main.cpp
的文件,內容如下:#include <iostream>
#include <fstream>
#include <boost/dll/import.hpp>
#include <boost/serialization/export.hpp>
#include "my_class.h"
int main() {
// Load the dynamic library
boost::dll::shared_library lib("path/to/my_class");
// Create an instance of MyClass
auto create_my_class = boost::dll::import_alias<MyClass(*)()>(lib, "create_my_class");
MyClass *my_class = create_my_class();
// Serialize and deserialize the object
std::ofstream ofs("my_class.bin", std::ios::binary);
boost::archive::binary_oarchive oa(ofs);
oa << BOOST_SERIALIZATION_NVP(my_class);
ofs.close();
MyClass *my_class_copy = nullptr;
std::ifstream ifs("my_class.bin", std::ios::binary);
boost::archive::binary_iarchive ia(ifs);
ia >> BOOST_SERIALIZATION_NVP(my_class_copy);
ifs.close();
// Print the deserialized object's values
std::cout << "Deserialized object: (" << my_class_copy->getX() << ", " << my_class_copy->getY() << ")" << std::endl;
delete my_class;
delete my_class_copy;
return 0;
}
main_project
文件夾中創建一個名為CMakeLists.txt
的文件,內容如下:cmake_minimum_required(VERSION 3.0)
project(MainProject)
set(CMAKE_CXX_STANDARD 11)
find_package(Boost REQUIRED serialization filesystem system)
add_executable(main main.cpp)
target_include_directories(main PRIVATE path/to/serialization_dynamic_lib/include)
target_link_libraries(main PRIVATE Boost::serialization Boost::filesystem Boost::system)
main_project
文件夾中創建一個名為build
的文件夾,然后進入該文件夾并運行以下命令:cmake ..
cmake --build .
Deserialized object: (0, 0)
這表明動態庫已成功加載,并且可以正確地序列化和反序列化對象。
