Zeroc ICE的示例

Zeroc ICE中间件号称标准统一，开源，跨平台，跨语言，分布式，安全，服务透明，负载均衡，面向对象，性能优越，防火期穿透，通讯屏蔽。因此相比Corba，DCOM，SOAP，J2EE等的中间件技术，自然是集众多优点于一身，而却没有他们的缺点。

在Windows平台试用了一下Zeroc ICE。运行简单客户端服务器的测试程序，服务器端用C++写的，客户端用C#写的，确实可以互通。使用起来还是非常方便的。

一.ICE文件和生成文件
首先，需要写一个ice文件，如下：

//hello.ice
//zhouhh
//2006.7.21

#ifndef HELLO_ICE
#define HELLO_ICE

module Demo
{

interface Hello
{  
    //nonmutating 表示不会改变数据成员，相当于C++ 的const
    //idempotent 表示执行一次和执行多次没有区别。如x=1.
    nonmutating void sayHello();
    idempotent void shutdown();
 
};

};

#endif

然后在cmd下执行
slice2cpp hello.ice

生成两个文件：
Hello.cpp
Hello.h

// hello.h
// Ice version 3.1.0
// Generated from file `Hello.ice'

#ifndef __Hello_h__
#define __Hello_h__

#include <Ice/LocalObjectF.h>
#include <Ice/ProxyF.h>
#include <Ice/ObjectF.h>
#include <Ice/Exception.h>
#include <Ice/LocalObject.h>

#include <Ice/Outgoing.h>
#include <Ice/Incoming.h>
#include <Ice/Direct.h>
#include <Ice/StreamF.h>
#include <Ice/UndefSysMacros.h>

#ifndef ICE_IGNORE_VERSION
#   if ICE_INT_VERSION / 100 != 301
#       error Ice version mismatch!
#   endif
#   if ICE_INT_VERSION % 100 < 0
#       error Ice patch level mismatch!
#   endif
#endif

//////////////////////////////////////////////
二。新建项目并配置环境
然后在Visual studio 2003中生成一个win32 console的应用程序，名字叫hello
将两个生成的文件hello.h和hello.cpp加入到项目。

visual studio应该配置好ice的相关目录。
在“工具”－>“选项”里面的“项目”->“VC++目录”里配置好“可执行文件”，“库”和“头文件”的ICE路径。

再配置“项目”－“属性”
a.在C/C++项里的“运行时库”为多线程DLL（/MD),否则在编译时会出预编译错误：
fatal error C1189: #error :  "Only multi-threaded DLL libraries can be used with Ice!"

b.在"语言"里的“启用运行时类型信息”，选“是/GR”，否则编译时会出警告
 warning C4541: “dynamic_cast”用在了带 /GR- 的多态类型“IceDelegate::Ice::Object”上；可能导致不可预知的行为

c.预编译头选“不使用”,并将stdafx.h和stdafx.cpp两个文件去掉，为了兼容性。

d.链接器的“输入”项的“附加依赖项”，填上“ice.lib iceutil.lib”，否则会出一堆下面的错误：
error LNK2019: 无法解析的外部符号 "__declspec(dllimport) public: void __thiscall IceUtil::Shared::__incRef(void)"
(__imp_?__incRef@Shared@IceUtil@@QAEXXZ) ，该符号在函数
"void __cdecl IceInternal::incRef(class IceProxy::FlowCtrlService::MediaGateWayCtrl *)"
 (?incRef@IceInternal@@YAXPAVMediaGateWayCtrl@FlowCtrlService@IceProxy@@@Z) 中被引用
 
设置完成后，编译，将所有错误去掉，让编译通过。

 

三。完成服务器端代码
新建一个类HelloI,从Demo::Hello继承，并实现其两个虚函数
    virtual void sayHello(const Ice::Current&) const;
    virtual void shutdown(const Ice::Current&);

代码如下：
//helloi.h
//zhouhh
//2006.7.21
#ifndef HELLO_I_H
#define HELLO_I_H

#include <Hello.h>

class HelloI : public Demo::Hello
{
public:

    virtual void sayHello(const Ice::Current&) const;
    virtual void shutdown(const Ice::Current&);
};

#endif

////////////////////////////
//helloi.cpp
//zhouhh
//2006.7.21
#include <HelloI.h>
#include <Ice/Ice.h>

using namespace std;

void
HelloI::sayHello(const Ice::Current&) const
{
    cout << "Hello World!" << endl;
}

void
HelloI::shutdown(const Ice::Current& c)
{
    cout << "Shutting down..." << endl;
    c.adapter->getCommunicator()->shutdown();
}
////////////////////////////////
至此，接口已经实现完毕。
除了实现接口，还要实现主线程循环。

新建一个类叫HelloServer,从Ice::Application继承，实现其虚函数run().
//helloserver.cpp
//zhouhh
//2006.7.21
#include <HelloI.h>
#include <Ice/Application.h>

using namespace std;

class HelloServer : public Ice::Application
{
public:

    virtual int run(int, char*[]);
};

int
main(int argc, char* argv[])
{
    HelloServer app;
   
    //app.main会实现一系列自动处理。Ice::Application是一个单件。
    return app.main(argc, argv, "config.server");
}

int
HelloServer::run(int argc, char* argv[])
{
  //创建对象适配器。对象适配器是servant的容器。一个容器内每个servant的名字都要不一样。
    Ice::ObjectAdapterPtr adapter = communicator()->createObjectAdapter("Hello");
   
    //将服务程序HelloI new出来，用智能指针存放。注意这是抽象基类的智能指针。
    //如果要该类智能指针，可以用typedef IceUtil::Handle<HelloI> HelloIPtr来定义。
    ::Demo::HelloPtr hello = new HelloI;
   
    //生成服务程序在对象适配器的ID
    //可以用 = communicator()->stringToIdentity("hello");
    //也可以这样写：
    Ice::Identity id ;
    id.name = "hello";
   
    //将服务程序加到对象适配器中，让Ice的runtime知道服务程序的存在。
    adapter->add(hello, id);//此处会导致智能指针的引用计数加1，所以服务程序实例不会丢失。
    adapter->activate();
    communicator()->waitForShutdown();
    return EXIT_SUCCESS;
}

/////////////////////////////////////////

四：客户端创建.
//helloClient.cpp
//zhouhh
//2006.7.21
#include <Ice/Application.h>
#include <Hello.h>

using namespace std;
using namespace Demo;

class HelloClient : public Ice::Application
{
public:

    virtual int run(int, char*[]);

};

int
main(int argc, char* argv[])
{
    HelloClient app;
    return app.main(argc, argv, "config.client");
}

int
HelloClient::run(int argc, char* argv[])
{
  //获取property 智能指针，用于处理config信息
    Ice::PropertiesPtr properties = communicator()->getProperties();
   
    //读取property“Hello.Proxy”
    const char* proxyProperty = "Hello.Proxy";
    string proxy = properties->getProperty(proxyProperty);
    if(proxy.empty())
    {
   cerr << argv[0] << ": property `" << proxyProperty << "' not set" << endl;
   return EXIT_FAILURE;
  }

    //根据配置生成一个代理的智能指针
    HelloPrx helloProxy = HelloPrx::checkedCast(
   communicator()->stringToProxy(proxy)->ice_twoway()->ice_timeout(-1)->ice_secure(false));
   
    if(!helloProxy)
    {
   cerr << argv[0] << ": invalid proxy" << endl;
   return EXIT_FAILURE;
    }

  try
  {
   helloProxy->sayHello();
  }
  catch(const Ice::Exception& ex)
  {
     cerr << ex << endl;
  }

    return EXIT_SUCCESS;
}

五.配置文件：
#config.client
#-h 10.130.205.182是远程测试时的配置，本机可以不用。10.130.205.182是服务器运行的地址
Hello.Proxy=hello:tcp -h 10.130.205.182 -p 10000:udp -h 10.130.205.182 -p 10000:ssl -h 10.130.205.182 -p 10001
#
# SSL Configuration
#
#将ice系统目录certs目录下的证书拷到当前目录下。
Ice.Plugin.IceSSL=IceSSL:createIceSSL
IceSSL.DefaultDir=certs
IceSSL.CertAuthFile=cacert.pem
IceSSL.CertFile=c_rsa1024_pub.pem
IceSSL.KeyFile=c_rsa1024_priv.pem

////////////////////////////
#config.server
Hello.Endpoints=tcp -p 10000:udp -p 10000:ssl -p 10001
#
# SSL Configuration
#
#将ice系统目录certs目录下的证书拷到当前目录下。
Ice.Plugin.IceSSL=IceSSL:createIceSSL
IceSSL.DefaultDir=certs
IceSSL.CertAuthFile=cacert.pem
IceSSL.CertFile=c_rsa1024_pub.pem
IceSSL.KeyFile=c_rsa1024_priv.pem

至此，一个基于Ice的测试程序就可以运行了！
