Ubuntu下搭建 ice 开发环境
Ubuntu上安装Ice 3.3很方便 ，软件源里有，直接apt-get就可以要安装Ice 3.4需要自己下载源码，编译安装，安装之前要安装Ice所依赖的软件包
apt-get install libdb4.6++-dev libbz2-dev bzip2 libssl-dev libreadline5-dev libexpat1-dev mcppI 然后：下载Ice-3.4.1.tar.gz
下载后安装解压，进入cpp目录，运行make ，make install 进行安装，默认安装路径在/opt/Ice-3.4.1
安装完后添加环境变量：
vi~/.bashrc 添加如下内容：
export ICE_HOME=/opt/Ice-3.4.1export PATH=$ICE_HOME/bin:$PATHexport LD_LIBRARY_PATH=$ICE_HOME/lib:$LD_LIBRARY_PATH 然后你就可以使用如下命令去生成代码了：
slice2cpp slice2freeze slice2html slice2php slice2rbslice2cs slice2freezejslice2java slice2py 如果我们使用java开发ice接口需要Ice.jar，进入java目录，运行ant build.xml ,会在lib目录下生成Ice.jar
如果我们使用python开发ice接口需要安装ice-python 使用命令：sudo apt-get install ice-python 安装
下面来做一个小例子：
slice文件：
module com{module demo{module mingfei{module core{module generated{struct Person{string name;int age;};sequence<Person> personList;dictionary<string,Person> personMap;interface HelloMingFei{string hello(string name);personList getPersonList();personMap getPersonMap();};};};};};}; 我们使用python开发server端：
server.py:
import sys,traceback,Ice,IcePyIce.loadSlice("Test.ice")import com.demo.mingfei.core.generatedclassHelloMingFeiI(com.demo.mingfei.core.generated.HelloMingFei ): def hello(slef ,s,current=None): return "hello %s" % s def getPersonList(self,current=None): p1 = com.demo.mingfei.core.generated.Person("mingfei",1) p2 = com.demo.mingfei.core.generated.Person("mingtao",2) personList = return personList def getPersonMap(self,current=None): p1 = com.demo.mingfei.core.generated.Person("mingfei",1) personDict = {"mingfei":p1} p2 = com.demo.mingfei.core.generated.Person("mingtao",2) personDict["mingtao"] = p2 return personDict status = 0ice = Nonetry: ic = Ice.initialize(sys.argv) adapter = ic.createObjectAdapterWithEndpoints("HelloMingFeiAdapter","default -p 10000") objectI = HelloMingFeiI() adapter.add(objectI,ic.stringToIdentity("HelloMingFei")) adapter.activate() ic.waitForShutdown()except: traceback.print_exc() status = 1if ic : #Clean up try: ic.destroy() except: traceback.print_exc() status = 1 sys.exit(status) 使用java来开发client：
首先使用slice2java Test.ice 生成java代码
Client.java:
package com.demo.mingfei.core.generated;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("HelloMingFei:default -p 10000"); HelloMingFeiPrx printer = HelloMingFeiPrxHelper.checkedCast(base) ; if (printer == null) { System.out.println("invalid proxy"); } String out = printer.hello("mingfei"); System.out.println(out); } catch (Ice.LocalException e) { e.printStackTrace(); status = 1; } catch (Exception e) { System.err.print(e.getMessage()); status = 1; } finally { if (ic != null) { ic.destroy(); } } System.exit(status);}}再讲一讲使用java开发server： 首先使用slice2java Test.ice 生成java代码package com.demo.mingfei.core.generated;import java.util.HashMap;import java.util.Map;import Ice.Current;public class Server extends _HelloMingFeiDisp{@Overridepublic Person[] getPersonList(Current current) {Person p1 = new Person();p1.name = "mingtao";p1.age = 2;return new Person[]{p1};}@Overridepublic Map<String, Person> getPersonMap(Current current) {Person p1 = new Person();p1.name = "mingtao";p1.age = 2;Person p2 = new Person();p2.name = "mingfei";p2.age = 2;Map<String,Person> map = new HashMap<String,Person>();map.put("mingtao", p1);map.put("mingfei", p2);return map;}@Overridepublic String hello(String name, Current current) {// TODO Auto-generated method stubreturn "hello " + name;}public static void main(String [] args){int status = 0; Ice.Communicator ic = null; try { ic = Ice.Util.initialize(args);// 初始化参数 Ice.ObjectAdapter adapter = ic.createObjectAdapterWithEndpoints( "HelloMingFeiAdapter", "default -p 10000");// 创造对象适配器 Ice.Object objcet = new Server();// 创建servant对象 adapter.add(objcet, Ice.Util.stringToIdentity("HelloMingFei"));// 适配器添加一个新的servant，给servant对象取个名字 adapter.activate(); System.out.println("connection success"); ic.waitForShutdown(); } catch (Ice.LocalException e) { e.printStackTrace(); status = 1; } catch (Exception e) { System.err.print(e.getMessage()); status = 1; } finally { if (ic != null) { ic.destroy(); } } System.exit(status);}}使用python开发client：
