if(v && !handle) { IceInternal::Ex::throwUOE(::Demo::CallbackSender::ice_staticId(), v); }}第三步：根据业务实现接口
接口CallbackSender的实现,这个接口由服务端使用,同时CallbackReceiver接口在client.cpp中实现，由客户端使用
CallbackI.h
// **********************************************************************//// Copyright (c) 2003-2016 ZeroC, Inc. All rights reserved.//// **********************************************************************#ifndef CALLBACK_I_H#define CALLBACK_I_H#include <IceUtil/IceUtil.h>#include <Callback.h>#include <set>class CallbackSenderI;typedef IceUtil::Handle<CallbackSenderI> CallbackSenderIPtr;class CallbackSenderI : public Demo::CallbackSender, public IceUtil::Thread, public IceUtil::Monitor<IceUtil::Mutex>{public: CallbackSenderI(const Ice::CommunicatorPtr&); void destroy(); virtual void addClient(const Ice::Identity&, const Ice::Current&); virtual void run();private: Ice::CommunicatorPtr _communicator; bool _destroy; std::set<Demo::CallbackReceiverPrx> _clients;};#endifCallbackI.cpp
// **********************************************************************//// Copyright (c) 2003-2016 ZeroC, Inc. All rights reserved.//// **********************************************************************#include <Ice/Ice.h>#include <CallbackI.h>using namespace std;using namespace Ice;using namespace Demo;CallbackSenderI::CallbackSenderI(const Ice::CommunicatorPtr& communicator) : _communicator(communicator), _destroy(false){}voidCallbackSenderI::destroy(){ { IceUtil::Monitor<IceUtil::Mutex>::Lock lck(*this); cout << "destroying callback sender" << endl; _destroy = true; notify(); } getThreadControl().join();}voidCallbackSenderI::addClient(const Identity& ident, const Current& current){ IceUtil::Monitor<IceUtil::Mutex>::Lock lck(*this); cout << "adding client `" << _communicator->identityToString(ident) << "'"<< endl; CallbackReceiverPrx client = CallbackReceiverPrx::uncheckedCast(current.con->createProxy(ident)); _clients.insert(client);}voidCallbackSenderI::run(){ int num = 0; bool destroyed = false; while(!destroyed) { std::set<Demo::CallbackReceiverPrx> clients; { IceUtil::Monitor<IceUtil::Mutex>::Lock lck(*this); timedWait(IceUtil::Time::seconds(2)); if(_destroy) { destroyed = true; continue; } clients = _clients; } if(!clients.empty()) { ++num; for(set<CallbackReceiverPrx>::iterator p = clients.begin(); p != clients.end(); ++p) { try { (*p)->callback(num); } catch(const Exception& ex) { cerr << "removing client `" << _communicator->identityToString((*p)->ice_getIdentity()) << "':\n" << ex << endl; IceUtil::Monitor<IceUtil::Mutex>::Lock lck(*this); _clients.erase(*p); } } } }}第四步：实现客户端与服务器
客户端实际就是实现了CallbackReceiver
说明：
1) 通信器communitor()
2)得到 CallbackSenderPrx server = communicator()->propertyToProxy("CallbackSender.Proxy")
3)为了实现服务器回调，客户端通过 communicator() 生成了一个空的适配器，相当于将客户端变成了一个服务器
Ice::ObjectAdapterPtr adapter = communicator()->createObjectAdapter("");
4)为servant CallbackReceiverI生成id ,并加入适配器
Ice::Identity ident;
ident.name = IceUtil::generateUUID();
ident.category = "";
CallbackReceiverPtr cr = new CallbackReceiverI;
adapter->add(cr, ident);
ident.name = IceUtil::generateUUID();
ident.category = "";
CallbackReceiverPtr cr = new CallbackReceiverI;
adapter->add(cr, ident);
5) 激活适配器
adapter->activate();
6)取客户端的通信器，并将上面的适配器加入这个通信器 server->ice_getConnection()->setAdapter(adapter);
7)将适配器做为server的客户端
server->addClient(ident);
8) 通信器检测事件并等待结束
communicator()->waitForShutdown();
// **********************************************************************//// Copyright (c) 2003-2016 ZeroC, Inc. All rights reserved.//// **********************************************************************#include <IceUtil/IceUtil.h>#include <Ice/Ice.h>#include <Callback.h>using namespace std;using namespace Demo;class CallbackReceiverI : public CallbackReceiver{public: virtual void callback(Ice::Int num, const Ice::Current&) { cout << "received callback #" << num << endl; }};class CallbackClient : public Ice::Application{public: virtual int run(int, char*[]);};intmain(int argc, char* argv[]){ CallbackClient app; return app.main(argc, argv, "config.client");}intCallbackClient::run(int argc, char*[]){ if(argc > 1) { cerr << appName() << ": too many arguments" << endl; return EXIT_FAILURE; } CallbackSenderPrx server = CallbackSenderPrx::checkedCast(communicator()->propertyToProxy("CallbackSender.Proxy")); if(!server) { cerr << appName() << ": invalid proxy" << endl; return EXIT_FAILURE; } Ice::ObjectAdapterPtr adapter = communicator()->createObjectAdapter(""); Ice::Identity ident; ident.name = IceUtil::generateUUID(); ident.category = ""; CallbackReceiverPtr cr = new CallbackReceiverI; adapter->add(cr, ident); adapter->activate(); server->ice_getConnection()->setAdapter(adapter); server->addClient(ident); communicator()->waitForShutdown(); return EXIT_SUCCESS;}server.cpp
说明：
1) 创建适配器时，Callback.Server 对应config.server 文件中的 Callback.Server.Endpoints=tcp -p 10000:ws -p 10002
2) 创建servant CallbackSenderIPtr sender = new CallbackSenderI(communicator());
3）将servant 加入适配器 adapter->add(sender, communicator()->stringToIdentity("sender"));
4) 激活适配器 .
adapter->activate();
5) svervant CallbackSenderI 除了实现Callback.ice中定义的接口外，还继承了IceUtil::Thread IceUtil::Monitor<IceUtil::Mutex>两个类，
使svervant CallbackSenderI 具有线程能力
启动线程 sender->start();
6)IceUtil::Monitor<IceUtil::Mutex> 这个类还不太清楚做什么，后面再回来改吧

config.server
## The server creates one single object adapter with the name# "Callback.Server".
