Ubuntu下搭建|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：
slice2cppslice2freezeslice2htmlslice2phpslice2rbslice2csslice2freezejslice2javaslice2py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 personList;
dictionary 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,IcePy
Ice.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 = [p1,p2]
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 personDictstatus = 0
ice = None
try:
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 = 1sys.exit(status)使用java来开发client：
首先使用slice2java Test.ice 生成java代码
【Ubuntu下搭建|Ubuntu下搭建 ice 开发环境】 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{
@Override
public Person[] getPersonList(Current current) {
Person p1 = new Person();
p1.name = "mingtao";
p1.age = 2;
return new Person[]{p1};
}
@Override
public Map getPersonMap(Current current) {
Person p1 = new Person();
p1.name = "mingtao";
p1.age = 2;
Person p2 = new Person();
p2.name = "mingfei";
p2.age = 2;
Map map = new HashMap();
map.put("mingtao", p1);
map.put("mingfei", p2);
return map;
}
@Override
public String hello(String name, Current current) {
// TODO Auto-generated method stub
return "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： client.py:
import sys,Ice,traceback
Ice.loadSlice("Test.ice")
import com.demo.mingfei.core.generatedstatus = 0
ice = None
try:
ic = Ice.initialize(sys.argv)
base = ic.stringToProxy("HelloMingFei:default -p 10000")
serviceI = com.demo.mingfei.core.generated.HelloMingFeiPrx.checkedCast(base)
if not serviceI:
raise RuntimeError("Invalid proxy")printserviceI.hello("mingfei")
print "\r\n"
personList =serviceI.getPersonList()
personListSize = len(personList)
for i in range(len(personList)):
print "my name is %s ,and %d years old" %(personList[i].name , personList[i].age)
print "\r\n"
personDict = serviceI.getPersonMap()
print "my name is %s ,and %d years old"%( personDict["mingfei"].name, personDict["mingfei"].age)
print "my name is %s ,and %d years old"% (personDict["mingtao"].name, personDict["mingtao"].age)except:
traceback.print_exc()
status = 1if ic:
# Clean up
try:
ic.destroy()
except:
traceback.print_exc()
status = 1sys.exit(status)
