Ice的HelloWorld(Java)

Ice是一种面向对象的中间间平台，入门ice，简单的HelloWorld是必不可少的。

一、写一个ice定义

　　ice用来定义接口、程序骨架的，方便远程调用。首先我们要使用ice专属的slice语言写一个ice定义。如下：

file_name:HelloWorld.ice

module myHelloWorld{
    interface HelloWorld{
        void say(string s);
    };
};

module相当于java中的包，是ice定义中必不可少的。

二、编译这个ice定义　　

　　要编译这个ice定义，首先要安装一个ice服务器，将其中的bin文件夹加入环境变量。跟jdk配置类似。然后使用其中的slice2java命令编译。

　　例如HelloWorld.ice文件放在我F盘的test文件夹，运行aaarticlea/png;base64,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" alt="" />，就可以在test目录出现如下文件：

alt="" />

　　myHelloWorld文件夹名是ice定义中的module名。

三、编写Servant类

　　servant类是ice服务器端提供操作调用的行为制品，它提供的是ice对象的实质内容。说白了，就是ice所定义的接口，在服务器端的实现类。

　　按照管理，servant类名是ice接口名加一个“I”后缀，如下：

package client;
 
import Ice.Current;
import myHelloWorld._HelloWorldDisp;
 
public class HelloWorldI extends _HelloWorldDisp{
 
    private static final long serialVersionUID = 1L;
 
    @Override
    public void say(String s, Current __current) {
        System.out.println("Hello World!"+" the string s is " + s);
    }
}

如上，servant类需要继承_HelloWorldDisp这个slice2java编译生成的抽象类。实现方法参数是原本的形参加一个Ice的Current对象。

四、编写远程的服务器类

package client;
public class Server {
 
    public static void main(String[] args)
    {
        int status = 0;
        // Communicator实例，是ice run time的主句柄
        Ice.Communicator ic = null;
        try
        {
            // 调用Ice.Util.Initialize()初始化Ice run time
            System.out.println("初始化ice run time...");
            ic = Ice.Util.initialize(args);
 
            // 创建一个对象适配器，传入适配器名字和在10000端口处接收来的请求
            System.out.println("创建对象适配器，监听端口10000...");
            Ice.ObjectAdapter adapter = ic.createObjectAdapterWithEndpoints("SimplePrinterAdapter", "default -p 10000");
 
            // 实例化一个PrinterI对象，为Printer接口创建一个servant
            System.out.println("为接口创建servant...");
            Ice.Object object = new HelloWorldI();
 
            // 调用适配器的add,告诉它有一个新的servant,传递的参数是刚才的servant,这里的“SimplePrinter”是Servant的名字
            System.out.println("对象适配器加入servant...");
            adapter.add(object, Ice.Util.stringToIdentity("SimplePrinter"));
 
            //调用适配器的activate()方法，激活适配器。被激活后，服务器开始处理来自客户的请求。
            System.out.println("激活适配器，服务器等待处理请求...");
            adapter.activate();
 
            //这个方法挂起发出调用的线程，直到服务器实现终止为止。或我们自己发出一个调用关闭。
            ic.waitForShutdown();
        } catch (Ice.LocalException e)
        {
            e.printStackTrace();
            status = 1;
        } catch (Exception e)
        {
            e.printStackTrace();
            status = 1;
        } finally
        {
            if (ic != null)
            {
                ic.destroy();
            }
        }
        System.exit(status);
    }
}

这个服务器类其实就寥寥几行代码，注释已经很清楚了。

五、编写客户端类

package client;
import myHelloWorld.HelloWorldPrx;
import myHelloWorld.HelloWorldPrxHelper;
 
public class Client {
 
    public static void main(String[] args)
    {
        int status = 0;
        // Communicator实例
        Ice.Communicator ic = null;
        try
        {
            // 调用Ice.Util.Initialize()初始化Ice run time
            ic = Ice.Util.initialize(args);
 
            // 获取远地打印机的代理
            Ice.ObjectPrx base = ic.stringToProxy("SimplePrinter:default -p 10000");
 
            // 将上面的代理向下转换成一个Printer接口的代理
            HelloWorldPrx helloWorld = HelloWorldPrxHelper.checkedCast(base);
 
            // 如果转换成功
            if (helloWorld == null)
            {
                throw new Error("Invalid proxy");
            }
 
            // 调用这个代理，将字符串传给它
            helloWorld.say("bar");
 
        } catch (Ice.LocalException e)
        {
            e.printStackTrace();
            status = 1;
        } catch (Exception e)
        {
            e.printStackTrace();
            status = 1;
        } finally
        {
            if (ic != null)
            {
                ic.destroy();
            }
        }
        System.exit(status);
    }
}

六、运行

　　先运行服务器，服务器线程一直运行等待，如下：　　

初始化ice run time...
创建对象适配器，监听端口10000...
为接口创建servant...
对象适配器加入servant...
激活适配器，服务器等待处理请求...

　　运行了客户端后，显示如下：

初始化ice run time...
创建对象适配器，监听端口10000...
为接口创建servant...
对象适配器加入servant...
激活适配器，服务器等待处理请求...
Hello World! the string s is bar

　　将客户端改一下 helloWorld.say("foo");，再运行，显示如下：

初始化ice run time...
创建对象适配器，监听端口10000...
为接口创建servant...
对象适配器加入servant...
激活适配器，服务器等待处理请求...
Hello World! the string s is bar
Hello World! the string s is foo
