CORAB命名服务实现的简单日程管理软件

1. CORBA准备：http://blog.csdn.net/javacmm2012/article/details/9005429

2 . 编写IDL文件，作为静态库供客户端和服务端调用，代码如下：

#ifndef IUserCfgServant_IDL_#define IUserCfgServant_IDL_struct  sDataTime{/*日期时间类型*/short iYear;short iMonth;short iDay;short iHour;short iMinute;short iSeconds;};struct sItem{/*用户Item数据结构*/short iItemId;/*对每一个用户来说的唯一Id*/sDataTime sStartTime;sDataTime sEndTime;string strLabel;};typedef sequence<sItem> seqItem;struct sUser{short iUserId;/*用户唯一Id*/string strUserName;/*用户名*/string strPassword;/*密码*/seqItem seqItems;/*用户的item集合*/};interface IUserCfgServant{//返回字符串string echoString(in string mesg);//加法运算long add(in long p1,in long p2);/// 用户注册boolean addUser( in string username, in string password );/// 查询用户是否存在，可用作客户端登陆与查询用户信息boolean queryUser( in string username, in string password, out sUser user );/// 更新用户信息，可用作删除Item，或者增加Item来用boolean updateUserInfo( in sUser user );};#endif ///<IUserCfgServant_IDL_

然后使用自定义工具tao_idl编译该文件，在VS2012配置如下：

注意：如果没有tao_idl.exe， 则转向CORBA工程编译工程名为TAO_IDL_EXE的工程，会在\ACE_wrappers\bin下生成tao_idl.exe

此后，将生成的*S.h*C.h*S.cpp*C.cpp添加到IDL工程，然后编译生成静态库IDL.lib

3. 编写服务端工程

新建个新工程，命名为Server， 新建个类CIUserCfgServant_i用于实现接口文件IDL中定义的所有方法，代码如下：

#ifndef ECHO_I_H_#define ECHO_I_H_#include <iostream>#include <iomanip>#include <fstream>#include <sstream>#include <vector>#include "../IDL/IUserCfgServantS.h"//命名服务类#include "orbsvcs/CosNamingC.h"class CIUserCfgServant_i:public POA_IUserCfgServant,public PortableServer::RefCountServantBase{public:CIUserCfgServant_i();virtual ~CIUserCfgServant_i();virtual char* echoString(const char* mesg);//实现加法运算virtual CORBA::Long add(::CORBA::Long p1, ::CORBA::Long p2);//增加用户virtual CORBA::Boolean addUser (const char * username,const char * password);//查询用户virtual CORBA::Boolean queryUser (const char * username,const char * password,sUser_out user);//更新用户信息virtual CORBA::Boolean updateUserInfo (const sUser & user);private:bool writeToFile();//将对象信息存入文件bool readFromFile();//读取用户信息private:std::vector<sUser> m_vecUser;//所有用户信息fstream m_filedata;//文件读取用};#endif  ///<ECHO_I_H_

编写注册命名服务（IUserCfgServant）的代码，如下：

#include <iostream>#include "IUserCfgServant_i.h"using namespace std;int main(int argc, char * argv[]){try {//初始化CORBACORBA::ORB_var orb = CORBA::ORB_init(argc, argv);CORBA::Object_var poa_object =orb->resolve_initial_references ("RootPOA");PortableServer::POA_var poa =PortableServer::POA::_narrow (poa_object.in ());PortableServer::POAManager_var poa_manager =poa->the_POAManager ();poa_manager->activate ();CORBA::Object_var naming_context_object  = orb->resolve_initial_references("NameService");CosNaming::NamingContext_var naming_context = CosNaming::NamingContext::_narrow (naming_context_object.in ());CosNaming::Name name (1);name.length (1); name[0].id = CORBA::string_dup ("IUserCfgServant"); CIUserCfgServant_i* myecho = new CIUserCfgServant_i(); IUserCfgServant_var echo_var = myecho->_this(); try { naming_context->bind(name, echo_var.in ()); } catch(CosNaming::NamingContext::AlreadyBound& ex) { cerr<< ex._info() << endl; naming_context->rebind(name, echo_var.in ()); } cout<<"server start success..."<<endl; orb->run(); poa->destroy(1,1); orb->destroy();}catch(CORBA::SystemException& e) {cerr << e._info() <<endl;cerr << "Caught CORBA::SystemException." << endl;}catch(CORBA::Exception& e) {cout<< e._info() << endl;cerr << "Caught CORBA::Exception." << endl;}catch(...) {cerr << "Caught unknown exception." << endl;}return 0;}

工程配置，包含CORBA所需要的库，加上指定的静态接口库IDL.lib，配置如图：

4.编写客户端工程：

新建个工程Client， 代码如下：

#include <iostream>#include <iomanip>#include <sstream>// TAO头文件#include "tao/AnyTypeCode/AnyTypeCode_methods.h"#include "tao/AnyTypeCode/Any.h"#include "tao/ORB.h"#include "tao/SystemException.h"#include "tao/Basic_Types.h"#include "tao/ORB_Constants.h"#include "tao/Object.h"#include "tao/String_Manager_T.h"#include "tao/Objref_VarOut_T.h"#include "tao/VarOut_T.h"#include "tao/Versioned_Namespace.h"#include "tao/PortableServer/PortableServer.h"#include "tao/PortableServer/Servant_Base.h"#include "tao/orbsvcs/Naming_Service/Naming_Service.h"// TAO头文件#include "../IDL/IUserCfgServantC.h"IUserCfgServant_var _varEchoMgr;CORBA::ORB_var _varORB;sUser _userInfo;bool _bIsLogin = false;void printHelp();//打印帮助菜单using namespace std;int main(int argc, char* argv[]) {try {// initialize orb_varORB = CORBA::ORB_init(argc, argv);// Obtain reference from servant IORCORBA::Object_var naming_context_object = _varORB->resolve_initial_references( "NameService" );if ( CORBA::is_nil(naming_context_object.in()) )return false;CosNaming::NamingContext_var naming_context = CosNaming::NamingContext::_narrow( naming_context_object.in() );/*CosNaming::Name name(1);name.length(1);name[0].id = CORBA::string_dup( "IControlUnitDeviceServant" );*/CosNaming::Name name(1);name.length(1);name[0].id = CORBA::string_dup( "IUserCfgServant" );CORBA::Object_var project_object = naming_context->resolve( name );if ( CORBA::is_nil(project_object.in()) )return false;// Now downcast the object reference to the appropriate type_varEchoMgr = IUserCfgServant::_narrow( project_object.in() );while( true ){// std::string temp;// cout<<"input a string:";// cin>>temp;// temp = _varEchoMgr->echoString( temp.c_str() );// cout<<"from server:"<<temp<<endl;// int a,b;// cout<<"input two integer:";// cin>>a>>b;// int result = _varEchoMgr->add(a,b);// cout<<a<<"+"<<b<<"="<<result<<endl;string command;cin>>command;if( "help" == command ){printHelp();}else if( "register" == command ){string username;string password;cin>>username;//用户名cin>>password;//密码if( !_varEchoMgr->addUser(username.c_str(),password.c_str())){cerr<<"username has been registered"<<endl;}else{cout<<"register success"<<endl;}}else if( "login" == command ){string username;string password;cin>>username;//用户名cin>>password;//密码sUser_var uservar;if( !_varEchoMgr->queryUser(username.c_str(),password.c_str(),uservar) ){cerr<<"invalid login"<<endl;}else{system("cls");cout<<"welcome "<<username<<endl;_userInfo = *uservar;_bIsLogin = true;}}else if( "add" == command ){if( _bIsLogin ){sItem item;//先读取开始时间char ch;cin>>item.sStartTime.iYear;cin>>ch;//跳过/cin>>item.sStartTime.iMonth;cin>>ch;//跳过/cin>>item.sStartTime.iDay;cin>>item.sStartTime.iHour;cin>>ch;//跳过:cin>>item.sStartTime.iMinute;cin>>ch;//跳过:cin>>item.sStartTime.iSeconds;//再读结束时间cin>>item.sEndTime.iYear;cin>>ch;//跳过/cin>>item.sEndTime.iMonth;cin>>ch;//跳过/cin>>item.sEndTime.iDay;cin>>item.sEndTime.iHour;cin>>ch;//跳过:cin>>item.sEndTime.iMinute;cin>>ch;//跳过:cin>>item.sEndTime.iSeconds;//再读Labelstring strTmp;cin>>strTmp;item.strLabel = CORBA::string_dup( strTmp.c_str() );int iLength = _userInfo.seqItems.length();if( 0==iLength ){item.iItemId = 1;}else{item.iItemId = _userInfo.seqItems[iLength-1].iItemId+1;}_userInfo.seqItems.length(iLength+1);_userInfo.seqItems[iLength] = item;if( _varEchoMgr->updateUserInfo(_userInfo) ){cout<<"add success"<<endl;}else{cout<<"add failed"<<endl;}}else {cerr<<"please login first"<<endl;}}else if( "querya" == command ){if( _bIsLogin ){//查询所有的Itemint iLength = _userInfo.seqItems.length();stringstream stream;for( int j = 0 ;j<iLength;

客户端的配置参见服务端的配置。

注意：对于在IDL中定义out参数的结构体或对象，需要在服务端或者客户端初始化，否则空指针会出现运行错误。

5. 启动命名服务

cd %TAO_ROOT%/orbsvcs/Naming_Service/
tao_cosnaming -m 0 -ORBEndpoint iiop://127.0.0.1:10000

注意：如果tao_cosnaming不存在，请编译Naming_Service工程，然后会生成该可执行文件，其中127.0.0.1:10000是目的主机的IP和端口号，这里设为本地

6. 启动服务端

Server.exe -ORBInitRef NameService=iioploc://127.0.0.1:10000/NameService

7.启动客户端

Client.exe -ORBInitRef NameService=iioploc://127.0.0.1:10000/NameService
