django框架（一） 基于logging的sigton实现

import loggingimport logging.configimport osfrom RescSystemMng.settings import BASE_DIR__all__=['GetInstance' ,'debug']class LogHandle(object):    __sigton=None    def __init__(self):        self.path=os.path.join( BASE_DIR , "../conf/logger.conf" )          print( self.path  )        logging.config.fileConfig( self.path )         self.logger = logging.getLogger("example01")    def GetInstance(self):        if LogHandle.__sigton is None:            LogHandle.__sigton=LogHandle()        return LogHandle.__sigton     def debug(self , msg):        self.logger.debug(msg)    def info(self , msg):        self.logger.info(msg)    def warn(self , msg):        self.logger.warn(msg)

logger.conf内容如下
