使用asio库的Active Object模式来管理共享数据，以避免对互斥锁的需求。

示例代码：

#include #include #include #include

using namespace boost::asio;

class ActiveObject { public: ActiveObject() : service_(), work_(service_) { thread_ = std::thread(boost::bind(&io_service::run, &service_)); }

~ActiveObject() {
    service_.stop();
    thread_.join();
}

template
void post(Handler handler) {
    service_.post(handler);
}

private: io_service service_; work work_; std::thread thread_; };

class SharedData { public: SharedData() : value_(0) {}

void increment() {
    value_++;
}

int get() const {
    return value_;
}

private: int value_; };

class DataHandler { public: DataHandler(ActiveObject& active_object, SharedData& data) : active_object_(active_object), data_(data) {}

void increment() {
    active_object_.post(boost::bind(&DataHandler::handleIncrement, this));
}

private: void handleIncrement() { data_.increment(); }

ActiveObject& active_object_;
SharedData& data_;

};

int main() { ActiveObject active_object;

SharedData data;
DataHandler handler(active_object, data);

for (int i = 0; i < 1000; ++i) {
    handler.increment();
}

boost::this_thread::sleep_for(boost::chrono::milliseconds(10));

std::cout << "Shared data value: " << data.get() << std::endl;

return 0;

}
