icebox相等於tomcat

1.新建IceBox的UserServiceServer

package com.yinzhen.demo.ice.userservice;

import Ice.Communicator;
import Ice.ObjectAdapter;
import IceBox.Service;

public class UserServiceServerIceBox implements Service{
	
	private ObjectAdapter adapter;
	
	@Override
	public void start(String paramString, Communicator communicator, String[] paramArgs) {
		
		//adapter = communicator.createObjectAdapterWithEndpoints("UserServiceAdapter","default -p 10006");
		adapter = communicator.createObjectAdapter(paramString);
		// 創建服務端代碼實現servant
		UserServiceImpl servant = new UserServiceImpl();
		// 將servant與ice對象標識符建立映射關係，並添加到ice對象適配器中
		adapter.add(servant, Ice.Util.stringToIdentity(paramString));
		// 激活對象適配器
		adapter.activate();
		System.out.println("UserService adapter activate");
		
		
	}

	@Override
	public void stop() {
		adapter.destroy();
		System.out.println("adapter has been destory");
	}

}

2.打包上傳到服務器 /opt/ice_project/app/userservice/lib

3.新建配置文件目錄/opt/ice_project/app/userservice/config

mkdir -p /opt/ice_project/app/userservice/config

4.新建icebox配置文件config.properties

IceBox.Service.UserServiceServer=com.yinzhen.demo.ice.userservice.UserServiceServerIceBox 
UserServiceServer.Endpoints=tcp -p 10006 -h 192.168.1.25
IceBox.InheritProperties=1

5.啓動腳本修改

echo "$JAVA_HOME/bin/java -Xms512M -Xmx512M -XX:PermSize=128m -XX:MaxPermSize=256m -cp  $CLASSPATH IceBox.Server --Ice.Config=$SERVER_HOME/config/config.properties"
$JAVA_HOME/bin/java -Xms512M -Xmx512M -XX:PermSize=128m -XX:MaxPermSize=256m -cp  $CLASSPATH IceBox.Server --Ice.Config=$SERVER_HOME/config/config.properties

6.啓動服務

./startIceServer.sh &

7.調用

package com.yinzhen.demo.ice.userservice;

import com.yinzhen.demo.ice.user.UserInfo;
import com.yinzhen.demo.ice.user.UserServicePrx;
import com.yinzhen.demo.ice.user.UserServicePrxHelper;

public class UserServiceClient {
	
	public static void main(String[] args) {
		Ice.Communicator communicator = null;
		try {
			//初始化ice通信器communicator,可以使用args傳入一下ice初始化的參數如超時時間，線程池大小等
			communicator = Ice.Util.initialize(args);
			// 傳入遠程服務單元的 ice對象標識符  協議默認tcp 主機 已經服務監聽端口 -h 172.16.20.220
			Ice.ObjectPrx op = communicator.stringToProxy("UserServiceServer:default -h 192.168.1.25  -p 10006");
			// 檢查通用客戶端代理op 是不是queryServer對象標識符所關聯的ice對象的代理
			UserServicePrx userServicePrx = UserServicePrxHelper.checkedCast(op);
			if(userServicePrx == null){
				throw new Exception("qp == null");
			}
			UserInfo userInfo = userServicePrx.getUserInfoById("id");
			if(userInfo == null){
				throw new Exception("userInfo == null");
			}
			// 輸出服務端返回結果
			System.out.println(userInfo.remark);
		} catch (Exception e) {
			// TODO: handle exception
			System.out.println(e);
		}

	}
