我有这个pydev项目,我学习了如何正确使用记录器

class SpeakingClass(object):
def __init__(self):
self.logger = logging.getLogger("%s.%s" % (__name__, "SpeakingClass"))
def speakingMethod(self):
self.logger.info("I'm a method from a SpeakingClass instance")
scripts.py
#!env python
# --*-- encoding: iso-8859-1 --*--
import logging
logger = logging.getLogger("%s.%s" % (__name__, "scripts"))
def anotherRandomMethod():
logger.info("Now I'm talking from core.scripts.anotherRandomMethod")
entrypoint.py
#!/usr/bin/env python
# --*-- encoding: iso-8859-1 --*--
import logging
from core.classHangar import SpeakingClass
from core.scripts import anotherRandomMethod
logger = logging.getLogger("%s.%s" % (__name__, "entrypoint"))
def randomMethod():
logger.info("Now I'm in the entrypoint.randomMethod")
def methodCalledByCli():
logger.info("Now I'm in the entrypoint.methodCalledByCli")
randomMethod()
anotherRandomMethod()
speaking_object = SpeakingClass()
speaking_object.speakingMethod()
cliloggertest.py
#!env python
# --*-- encoding: iso-8859-1 --*--
import sys
sys.path.insert(0, '../src/')
import os
import logging.config
import util
from entrypoint import methodCalledByCli
def main():
logging.config.fileConfig(os.path.join(util.getProjectPath(), "config/logger.conf"))
logger = logging.getLogger("%s.%s" % (__name__, "cli"))
logger.info("I'm talking from the CLI script")
return methodCalledByCli()
if __name__ == "__main__":
sys.exit(main())
和logger.conf
[loggers]
keys=root
[handlers]
keys=syserr
[formatters]
keys=basicformatter
[logger_root]
level=DEBUG
handlers=syserr
[handler_syserr]
class=StreamHandler
formatter=basicformatter
args=(sys.stderr,)
[formatter_basicformatter]
format=%(asctime)s %(levelname)-9s%(name)-35s: %(message)s
datefmt=
我通常应该得到:
"I'm talking from the CLI script"
"Now I'm in the entrypoint.methodCalledByCli"
"Now I'm in the entrypoint.randomMethod"
"Now I'm talking from core.scripts.anotherRandomMethod"
"I'm a method from a SpeakingClass instance"
但我得到的只是:
"I'm talking from the CLI script"
"I'm a method from a SpeakingClass instance"
我不明白为什么,我要求记录器在cliloggertest.py和其他脚本中以完全相同的方式记录
ps:我正在发表cliloggertest.py
正如Mikko Ohtamaa所述,由于导入顺序,cli导入入口点,入口点导入脚本,因此在CLI中设置配置之前创建了脚本的记录器和入口点记录器
以这种方式更改cliloggertest解决了这个问题(在任何非内部python导入之前设置配置:
#!env python
# --*-- encoding: iso-8859-1 --*--
import sys
sys.path.insert(0, '../src/')
import os
import util
import logging.config
logging.config.fileConfig(os.path.join(util.getProjectPath(), "config/logger.conf"))
from entrypoint import methodCalledByCli
def main():
logger = logging.getLogger("cliloggertest")
logger.info("I'm talking from the CLI script")
return methodCalledByCli()
if __name__ == "__main__":
sys.exit(main())
答案 0 :(得分:1)
可能猜测这是导入问题的顺序以及您的应用程序如何设置自己。
有些记录器在logging.config.fileConfig()
呼叫之前创建,其他记录器在呼叫之后创建。
