(转)ICE实例（Eclipse与Slice2Java插件）

link：http://hi.baidu.com/dd_taiyangxue/blog/item/cc7f014442b4a82acffca382.html

一、准备条件

1、Eclipse3.4

2、Slice2Java插件：下载地址及使用说明：http://www.zeroc.com/eclipse.html，具体如下：

ZeroC hosts an Eclipse plug-in site that you can add to your Eclipse configuration. Follow these steps to install the Slice2Java plug-in:

1. From the Help menu, choose Software Updates
2. Select the Available Software tab
3. Click Add Site
4. In the Location field, enter http://www.zeroc.com/download/eclipse
5. Select the Slice2Java plug-in and click Install

The plug-in requires Ice 3.3.1 or later. Users of Ice for Android 0.1 may also use the plug-in but you must upgrade your Ice installation to version 3.3.1 or later.

安装成功后：点击Eclipse的Window——preferences,如下图：

3、Ice-3.3.1-VC80.msi安装，目录为D:\Ice-3.3.1。下载地址：http://www.zeroc.com/download.html

二、操作步骤

1、建立Java工程：MyTestICE

2、建立slice文件夹，在其目录下建立：Printer.ice，内容如下：

module PrinterInterface
{
interface Printer
{
void printString(string s);
};
};

3、使用Slice2Java插件（也可以使用命令行：slice2java Printer.ice）

右键点击工程“MyTestICE”——Slice2Java——Add Slice2Java builder，自动生成generated文件夹下的java文件，如下图所示：

 

 

4、编写servant类的PrinterI

package printer;

import Ice.Current;
import PrinterInterface._PrinterDisp;

@SuppressWarnings("serial")
public class PrinterI extends _PrinterDisp
{
    
    public void shutdown(Current arg0)
    {
        
    }
    
    public void writeMessage(String arg0, int arg1, Current arg2)
    {
        
    }
    
    public void printString(String s, Ice.Current current)
    {
        System.out.println("The string is : "+s);
    }
    
}

5、编写ICE的server

package server;

import printer.PrinterI;

public class Server
{
    public static void main(String[] args)
    {
        int status = 0;
        Ice.Communicator ic = null;
        try
        {
            ic = Ice.Util.initialize(args);
            Ice.ObjectAdapter adapter = ic.createObjectAdapterWithEndpoints(
                "SimplePrinterAdapter", "default -p 2888");
            Ice.Object object = new PrinterI();
            adapter.add(object, Ice.Util.stringToIdentity("SimplePrinter"));
            adapter.activate();
            ic.waitForShutdown();
        }
        catch (Ice.LocalException e)
        {
            e.printStackTrace();
            status = 1;
        }
        catch (Exception e)
        {
            System.err.println(e.getMessage());
            status = 1;
        }
        finally
        {
            if (ic != null)
                ic.destroy();
        }
        System.exit(status);
    }
}

6、编写client客户端

package client;

import PrinterInterface.PrinterPrx;

public class Client
{
    public static void main(String[] args)
    {
        int status = 0;
        Ice.Communicator ic = null;
        try
        {
            ic = Ice.Util.initialize(args);
            Ice.ObjectPrx base = ic
                .stringToProxy("SimplePrinter:default -h 10.130.14.49 -p 2888");
            PrinterPrx printer = PrinterPrxHelper.checkedCast(base);
            if (printer == null)
                throw new Error("Invalid proxy");
            printer.printString("Hello World!");
        }
        catch (Ice.LocalException e)
        {
            e.printStackTrace();
            status = 1;
        }
        catch (Exception e)
        {
            System.err.println(e.getMessage());
            status = 1;
        }
        finally
        {
            if (ic != null)
                ic.destroy();
        }
        System.exit(status);
    }
}

 

7、在另外的机器上允许Server，在本机运行Client，在运行Server的机器上输出：The string is:Hello World!
