(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:

From the Help menu, choose Software Updates
Select the Available Software tab
Click Add Site
In the Location field, enter http://www.zeroc.com/download/eclipse
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

View Code

 1 package printer;
 2 
 3 import Ice.Current;
 4 import PrinterInterface._PrinterDisp;
 5 
 6 @SuppressWarnings("serial")
 7 public class PrinterI extends _PrinterDisp
 8 {
 9     
10     public void shutdown(Current arg0)
11     {
12         
13     }
14     
15     public void writeMessage(String arg0, int arg1, Current arg2)
16     {
17         
18     }
19     
20     public void printString(String s, Ice.Current current)
21     {
22         System.out.println("The string is : "+s);
23     }
24     
25 }

5、编写ICE的server

View Code

 1 package server;
 2 
 3 import printer.PrinterI;
 4 
 5 public class Server
 6 {
 7     public static void main(String[] args)
 8     {
 9         int status = 0;
10         Ice.Communicator ic = null;
11         try
12         {
13             ic = Ice.Util.initialize(args);
14             Ice.ObjectAdapter adapter = ic.createObjectAdapterWithEndpoints(
15                 "SimplePrinterAdapter", "default -p 2888");
16             Ice.Object object = new PrinterI();
17             adapter.add(object, Ice.Util.stringToIdentity("SimplePrinter"));
18             adapter.activate();
19             ic.waitForShutdown();
20         }
21         catch (Ice.LocalException e)
22         {
23             e.printStackTrace();
24             status = 1;
25         }
26         catch (Exception e)
27         {
28             System.err.println(e.getMessage());
29             status = 1;
30         }
31         finally
32         {
33             if (ic != null)
34                 ic.destroy();
35         }
36         System.exit(status);
37     }
38 }

6、编写client客户端

View Code

 1 package client;
 2 
 3 import PrinterInterface.PrinterPrx;
 4 
 5 public class Client
 6 {
 7     public static void main(String[] args)
 8     {
 9         int status = 0;
10         Ice.Communicator ic = null;
11         try
12         {
13             ic = Ice.Util.initialize(args);
14             Ice.ObjectPrx base = ic
15                 .stringToProxy("SimplePrinter:default -h 10.130.14.49 -p 2888");
16             PrinterPrx printer = PrinterPrxHelper.checkedCast(base);
17             if (printer == null)
18                 throw new Error("Invalid proxy");
19             printer.printString("Hello World!");
20         }
21         catch (Ice.LocalException e)
22         {
23             e.printStackTrace();
24             status = 1;
25         }
26         catch (Exception e)
27         {
28             System.err.println(e.getMessage());
29             status = 1;
30         }
31         finally
32         {
33             if (ic != null)
34                 ic.destroy();
35         }
36         System.exit(status);
37     }
38 }

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!
