IceBox java 入门例子

IceBox的基本概念作用就不用说了。

Hello.ice  文件内容

#ifndef HELLO_ICE
#define HELLO_ICE
[["java:package:icebox.demo"]]
module slice2java
{
	interface Hello{
		void sayHello(string xx);
	};

};
#endif

生成java代码结构图如下：

业务实现类icebox.servant.HelloI.java  代码如下：

package icebox.servant;

 
import Ice.Current;
import icebox.demo.slice2java._HelloDisp;

public class HelloI extends _HelloDisp   {

	@Override
	public void sayHello(String xx, Current __current) {
		// TODO Auto-generated method stub
		System.out.println("Hello "+xx);
	}

 
}

IceBox服务类icebox.service.HelloServiceI.java

package icebox.service;

import icebox.servant.HelloI;
import Ice.Communicator;

public class HelloServiceI   implements IceBox.Service{
	private Ice.ObjectAdapter _adapter;
	@Override
	public void start(String arg0, Ice.Communicator communicator, String[] arg2) {
		// TODO Auto-generated method stub
        _adapter = communicator.createObjectAdapter(arg0);
        _adapter.add(new HelloI(), communicator.stringToIdentity("hello"));
        _adapter.activate();
	}

	@Override
	public void stop() {
		// TODO Auto-generated method stub
		_adapter.destroy();
	}
	
	
}

客户端实现类 icebox.client.HelloClient.java

package icebox.client;

        {
            try
            {
                communicator().destroy();
            }
            catch(Ice.LocalException ex)
            {
                ex.printStackTrace();
            }
        }
    }

    private void   menu()
    {
        System.out.println(
            "usage:\n" +

            "O: send greeting as batch oneway\n" +
            "d: send greeting as datagram\n" +
            "D: send greeting as batch datagram\n" +
            "f: flush all batch requests\n" +
            "x: exit\n" +
            "?: help\n");
    }

    @Override
    public int run(String[] args)
    {
        if(args.length > 0)
        {
            System.err.println(appName() + ": too many arguments");
            return 1;
        }

        //
        // Since this is an interactive demo we want to clear the
        // Application installed interrupt callback and install our
        // own shutdown hook.
        //
        setInterruptHook(new ShutdownHook());

        HelloPrx twoway = HelloPrxHelper.checkedCast(
            communicator().propertyToProxy("Hello.Proxy").ice_twoway().ice_timeout(-1).ice_secure(false));

config.client 配置文件内空

#
# The client reads this property to create the reference to the
# "hello" object in the server.

Hello.Proxy=hello:tcp -h localhost -p 20000:udp -h localhost -p 20000

#
# Warn about connection exceptions
#
Ice.Warn.Connections=1

#
# Network Tracing
#
# 0 = no network tracing
# 1 = trace connection establishment and closure
# 2 = like 1, but more detailed
# 3 = like 2, but also trace data transfer
#
#Ice.Trace.Network=1

#
# Protocol Tracing
#
# 0 = no protocol tracing
# 1 = trace protocol messages
#
#Ice.Trace.Protocol=1

config.icebox 配置文件

 
Ice.Admin.Endpoints=tcp -p 9996 -h localhost
Ice.Admin.InstanceName=DemoIceBox

#
# The hello service
#
IceBox.Service.Hello=C:\\tydic-wk-myeclipse\\NX_Pay\\bin\\hello.jar:icebox.service.HelloServiceI --Ice.Config=config.service
#IceBox.Service.Hello=classpath:icebox.service.HelloServiceI  --Ice.Config=config.service
#
# Warn about connection exceptions
#
  

config.service 配置文件内容：

#
# The server creates one single object adapter with the name of
# the service. The following line sets the endpoints for this
# adapter.
#
Hello.Endpoints=tcp -h localhost -p 20000:udp -h localhost -p 20000

#
# Warn about connection exceptions
#
Ice.Warn.Connections=1

#
# Network Tracing
#
# 0 = no network tracing
# 1 = trace connection establishment and closure
# 2 = like 1, but more detailed
# 3 = like 2, but also trace data transfer
#
#Ice.Trace.Network=1

#
# Protocol Tracing
#
# 0 = no protocol tracing
# 1 = trace protocol messages
#
#Ice.Trace.Protocol=1

至此所有代码和配置完成，把项目打包生成hello.jar 文件，放在C:\\tydic-wk-myeclipse\\NX_Pay\\bin 目录中。

在cmd下，cd   C:\tydic-wk-myeclipse\NX_Pay\\bin

执行

java   -Djava.ext.dirs=D:\ZeroC\Ice-3.6.1\lib\  -cp D:\ZeroC\Ice-3.6.1\lib\icebox-3.6.1.jar IceBox.Server --Ice.Config=config.icebox

-Djava.ext.dirs  设置依赖ice  jar包目录

-cp   因jar里没有 manifest 没设置main-class

icebox运行是执行icebox-3.6.1.jar 的  IceBox.Server类，该类会根据  --Ice.Config= config.icebox  配置文件，部署相关服务。

运行结果：
