IceDemos：Ice registry

为Registry写配置文件：registry.cfg

#registry config for icegrid#客户端通过Endpoints访问注册表IceGrid.Registry.Client.Endpoints=tcp -p 4061IceGrid.Registry.Server.Endpoints=tcpIceGrid.Registry.Internal.Endpoints=tcpIceGrid.Registry.AdminPermissionsVerifier=IceGrid/NullPermissionsVerifier#Registry的持久化文件存放目录，需要手工创建目录IceGrid.Registry.Data=./registry#是否允许动态注册，一般在开发阶段允许，而生产部署则关闭IceGrid.Registry.DynamicRegistration=1

在实验目录E:\var\iceDemos下创建registry的工作目录：

E:\Var\icegrid>mkdir registry

通过命令行工具icegridregistry启动registry服务：

E:\Var\icegrid>icegridregistry --Ice.Config=registry.cfg

在IceBox的配置文件中增加registry服务，将OnlineBook和HelloIce添加到registry上去，修改后的IceBox配置文件：config.properties

#server propertiesIceBox.InstanceName=MyAppIceBox 1IceBox.InheritProperties=1IceBox.PrintServicesReady=MyAppIceBox 1IceBox.ServiceManager.Endpoints=tcp -p 9999 -h localhost#performance propertiesIce.ThreadPool.Server.Size=4Ice.ThreadPool.Server.SizeMax=100Ice.ThreadPool.Server.SizeWarn=40Ice.ThreadPool.Client.Size=4Ice.ThreadPool.Client.SizeMax=100Ice.ThreadPool.Client.SizeWarn=40#for system strongerIce.ACM.Client=300Ice.ACM.Server=300#log and trace#Ice.LogFile=iceserv.logIce.PrintStackTraces=1Ice.Trace.Retry=2Ice.Trace.Network=2Ice.Trace.ThreadPool=1Ice.Trace.Locator=2Ice.Warn.Connections=1Ice.Warn.Dispatch=1Ice.Warn.Endpoints=1#service define beginIceBox.Service.HelloIce=com.myjava.ice.demo.impl.HelloIceImpl prop1=1 prop2=2 prop3=3HelloIce.Endpoints=tcp -p 10000 -h localhostIceBox.Service.OnlineBook=com.myjava.ice.demo.impl.OnlineBookImpl prop1=1 prop2=2 prop3=3OnlineBook.Endpoints=tcp -p 10001 -h localhost#使用ice registry增加以下配置###########Ice.Default.Locator=IceGrid/Locator:tcp -h localhost -p 4061HelloIce.AdapterId=HelloIceAdapterOnlineBook.AdapterId=OnlineBookAdapter################################service define end#service load orderIceBox.LoadOrder=HelloIce,OnlineBook#service share communicatorIceBox.UseSharedCommunicator.HelloIce=1IceBox.UseSharedCommunicator.OnlineBook=1

修改客户端的代码，现在可以不用在客户端内指定服务的端口和地址了。
OnlineBookClient.java

package com.myjava.ice.demo.impl;import com.myjava.ice.demo.Message;import com.myjava.ice.demo.OnlineBookPrx;import com.myjava.ice.demo.OnlineBookPrxHelper;public class OnlineBookClient {    public static void main(String[] args){        Ice.Communicator ic = null;        //初始化参数指定registry的地址        String[] initParams = new String[] {"--Ice.Default.Locator=IceGrid/Locator:tcp -h localhost -p 4061"};        ic = Ice.Util.initialize(initParams);        //获取OnlineBook服务时不需要指定端口和地址        Ice.ObjectPrx base = ic.stringToProxy("OnlineBook@OnlineBookAdapter");        OnlineBookPrx proxy = OnlineBookPrxHelper.checkedCast(base);        if(proxy == null)            throw new Error("Invalid proxy.");        Message msg = new Message();        msg.name = "Mr. wang";        msg.type = 3;        msg.price = 99.9;        msg.valid =true;        msg.content = "OnlineBook Ice.";        Message ret = proxy.bookTick(msg);        System.out.println(ret.content);        if(ic != null)            ic.destroy();    }}
