All rights reserved.//// **********************************************************************#include <IceUtil/IceUtil.h>#include <Ice/Ice.h>#include <HelloI.h>using namespace std;voidHelloI::sayHello(int delay, const Ice::Current&){ if(delay != 0) { IceUtil::ThreadControl::sleep(IceUtil::Time::milliSeconds(delay)); } cout << "Hello World!" << endl;}voidHelloI::shutdown(const Ice::Current& c){ cout << "Shutting down..." << endl; c.adapter->getCommunicator()->shutdown();}第四步：实现客户端与服务器
client.cpp
说明：
1) communicator() 得到 通信器(Ice::Communicator),这个例子中没有说明怎样自己构造一个通信器，后面学习时再看
2) 由通信器去得到Proxy对象，现在不清楚有多少种方法可以得到代理对象，例子是通过字符串得到的，"Hello.proxy"对应
config.client 中的 Hello.Proxy=hello:tcp -p 10000:udp -p 10000:ssl -p 10001
3)通信方式由Proxy对象控制，例子中是通过下面方法调用
双向: HelloPrx twoway = propertyToProxy("Hello.Proxy")->ice_twoway()
单向: HelloPrx oneway = twoway->ice_oneway();
批量单向: HelloPrx batchOneway = twoway->ice_batchOneway();
数据报: HelloPrx datagram = twoway->ice_datagram();
批量数据报: HelloPrx batchDatagram = twoway->ice_batchDatagram();
4)对量通信发送数据后，通过调用下面的方法刷新(真正将数据发送出去)
batchOneway->ice_flushBatchRequests();
batchDatagram->ice_flushBatchRequests();
5)设置发送超时时间间隔,单位ms
twoway = twoway->ice_invocationTimeout(timeout);
oneway = oneway->ice_invocationTimeout(timeout);
batchOneway = batchOneway->ice_invocationTimeout(timeout);
6)设置是否走安全通道 是(true) 否(false),安全通道时，证书路径在配置文件中
twoway = twoway->ice_secure(secure);
oneway = oneway->ice_secure(secure);
batchOneway = batchOneway->ice_secure(secure);
datagram = datagram->ice_secure(secure);
batchDatagram = batchDatagram->ice_secure(secure);
7) 调用是客户端传递参数，服务端执行后返回结果(有结果返回时，应该是twoway)

说明：
1)例子通过communitor()得到通信器
2)通过通信器得到对象适配器,例子是适配Hello接口,实际可能会有多个接口 Ice::ObjectAdapterPtr adapter = communicator()->createObjectAdapter("Hello");
“Hello" 对应config.server文件中的 Hello.Endpoints=tcp -p 10000:udp -p 10000:ssl -p 10001:ws -p 10002:wss -p 10003
3) 创建servant ,并将其加入适配器
Demo::HelloPtr hello = new HelloI;
adapter->add(hello, communicator()->stringToIdentity("hello"));
4)激活适配器
adapter->activate();
5)通信器 wait for exit
communicator()->waitForShutdown();
问题：
1) HelloServer从App继承，线程方法是通过communicator()等待结束事件的，如果多线程时应该怎样处理比较好呢?
