本書後面的SpringPython錯誤：AttributeError：'module'對象沒有屬性'ObjBase'

那麼，我買了本書Spring Python 1.1，我一直面臨着一些我無法解決的問題。我將編寫每個文件的代碼，以確保一切都清晰。如果你們中的一些人知道什麼是問題，請讓我知道，因爲我很絕望。本書後面的SpringPython錯誤：AttributeError：'module'對象沒有屬性'ObjBase'

simple_service.py

class Service(object): 
def happy_birthday(self, name): 
    results = [] 
    for i in range(4): 
     if i <= 2: 
      results.append("Happy birthday dear %s!" % name) 
     else: 
      results.append("Happy birthday to you!") 
      return results

simple_service_server_ctx.py

from springpython.config import * 
from springpython.remoting.pyro import * 

from simple_service import * 

class HappyBirthdayContext(PythonConfig): 
    def __init__(self): 
     PythonConfig.__init__(self) 

    @Object 
    def target_service(self): 
     return Service() 

    @Object 
    def service_exporter(self): 
     exporter = PyroServiceExporter() 
     exporter.service = self.target_service() 
     exporter.service_name = "service" 
     exporter.service_host = "127.0.0.1" 
     exporter.service_port = "7766" 
     exporter.after_properties_set() 
     return exporter

simple_server.py

from springpython.context import * 
from simple_service_server_ctx import * 

if __name__ == "__main__": 
    ctx = ApplicationContext(HappyBirthdayContext()) 
    ctx.get_object("service_exporter")

我在終端上運行：蟒蛇simple_server ，然後我得到了以下錯誤：

（：simple_service_server_ctx.py文件）：

exporter.after_properties_set()

，因爲我讀了，它必須聲明（第19行，link to source code）10

我有我自己的行補充說。

在此先感謝。

我想知道你的Pyro版本是什麼。這裏使用Ubuntu 10.04中的Pyro 3.9.1-1，我沒有運行你的代碼的問題。難道你使用的是Pyro 4.x，如果我記得正確的話在這本書發佈後發佈了嗎？
