您要做的是对所有记录器应用一个筛选器，这样您就可以控制发出的内容。我能找到的将filter应用于所有记录器的唯一方法是，用从logging.Logger派生的东西初始化logging Logger类，并在那里应用filter。如是：

class MyFilter(logging.Filter):
    def filter(self, record):
        if record.name != 'BBProposalGenerator':
            return False
        return True

class MyLogger(logging.Logger):
    def __init__(self, name):
        logging.Logger.__init__(self, name)
        self.addFilter(MyFilter())

然后您所要做的就是，在实例化任何记录器之前，将默认记录器类设置为派生类，如下所示：

logging.setLoggerClass(MyLogger)
logging.basicConfig(level=logging.INFO)

希望这能有所帮助！
