django框架（一） 基於logging的sigton實現

import logging
import logging.config
import os
from 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內容如下
