Pyro简单使用(二)

上文讲到SpringPython对Pyro进行了封装，方便用户调用。看看代码：

from springpython.config import PythonConfig
from springpython.config import Object
from springpython.remoting.pyro import PyroServiceExporter
from springpython.remoting.pyro import PyroProxyFactory
from Demo import Echo
class WebServiceContainer(PythonConfig):
    def __init__(self):
        super(WebServiceContainer,self).__init__()
        
    @Object(lazy_init=True)
    def my_web_service(self):
        service=PyroServiceExporter(
            service=Echo(),service_name="echo",service_port=9000
        )
        return service
    
    @Object(lazy_init=True)
    def my_web_client(self):
        factory=PyroProxyFactory()
        factory.service_url='PYROLOC://localhost:9000/echo'
        return factory

WebServiceContainer类继承了SpringPython的PythonConfig，这样WebServiceContainer就拥有了类似Spring的功能，比如可以获得bean。

@Object表示注解，表明其下的方法是一个bean。lazy_init表示延时加载，类似spring。

现在，我们来发布Pyro服务：

#coding=utf-8
from springpython.context import ApplicationContext
from WebServiceContainer import WebServiceContainer
if __name__=='__main__':
    context=ApplicationContext(WebServiceContainer())
    #获得bean
    server=context.get_object("my_web_service")
    #启动服务
    server.after_properties_set()
    

客户端连接：

#coding=utf-8
from springpython.context import ApplicationContext
from WebServiceContainer import WebServiceContainer
context=ApplicationContext(WebServiceContainer())
client=context.get_object("my_web_client")
print client.say_hello("zhaolei")
print client.say_hello("石头")

一切都很简单，有机会可以看看SpringPython，还是有点意思的。:-)
