libevent for qt网络模块,直接替换qt的select模型,支持epoll,select,pool.使用非常简单,无需修改以前的代码结构

最近在开发im服务器，需要大并发链接。QT默认的是使用select模型的，这种轮询方式非常慢。在高并发连接,我们需要epoll才能发挥linux服务器的性能.而且使用简单,整个服务端代码架构无需修改,设置QT的分发事件就可以使用了,只要在main里面添加 :

int main(int argc, char *argv[])  
{  
  #ifdef Q_OS_LINUX  
    QCoreApplication::setEventDispatcher(new EventDispatcherLibEvent);  
   // qInstallMessageHandler(customMessageHandler);  
  #endif  
  
  QCoreApplication a(argc, argv);  
    
  auto *ser=new ConfigServer;  
  ser->startServer();
 
  return a.exec();  
}


在.pro文件添加

}

可以直接跨平台了使用了
