log4j.properties 未读取所有附加程序

Question

我有一个 log4j.properties，里面有多个 appender。设置 -Dlog4j.debug 后，我看到以下输出

log4j: Using URL [jar:file:/opt/local/blah/brian/vfabric-tc-server-developer-2.9.5.SR1/TCInstance-A/lib/Command-service-0.0.10-SNAPSHOT-dev1.jar!/log4j.properties] for automatic log4j configuration.
log4j: Reading configuration from URL jar:file:/opt/local/blah/brian/vfabric-tc-server-developer-2.9.5.SR1/TCInstance-A/lib/Command-service-0.0.10-SNAPSHOT-dev1.jar!/log4j.properties
log4j: Parsing for [root] with value=[INFO].
log4j: Level token is [INFO].

log4j: Parsing for [ItOpsLogger] with value=[INFO, ITOPSLOG].

log4j: Category ItOpsLogger set to INFO
log4j: Parsing appender named "ITOPSLOG".

log4j: Setting property [conversionPattern] to [[%d{yyyy/MM/dd HH:mm:ss.SSS}][%p][][][%h][%m]%n].
log4j: End of parsing for "ITOPSLOG".
log4j: Setting property [file] to [~/tmpAlertFiles].
log4j: Setting property [maxFileSize] to [1MB].
log4j: Setting property [threshold] to [INFO].
log4j: Setting property [maxBackupIndex] to [2].
log4j: setFile called: ~/tmpAlertFiles, true
log4j: setFile ended
log4j: Parsed "ITOPSLOG" options.
log4j: Handling log4j.additivity.ItOpsLogger=[null]
log4j: Finished configuring.
log4j:WARN No appenders could be found for logger (org.springframework.context.support.ClassPathXmlApplicationContext).
log4j:WARN Please initialize the log4j system properly.
log4j:WARN See http://logging.apache.org/log4j/1.2/faq.html#noconfig for more info.

如您所见，尽管我在其中有其他附加程序，但我看到的唯一输出是否为 ITOPSLOG。然后我收到了

log4j:WARN No appenders could be found for logger (org.springframework.context.support.ClassPathXmlApplicationContext).

我已确保 commons-logging 不在我的类路径中，并且我的类路径中有 jcl-over-slf4j、slf4j-api、slf4j 和 log4j。

这是我的 log4j.properties。有什么想法吗？

Answer 1

你有：

# NOTE THAT YOU HAVE SPECIFIED NO APPENDERS!!!!
log4j.rootCategory=INFO

所以默认情况下，您的日志不会使用任何附加程序。 ITOPSLOG 之所以有效，是因为您已经指定了更远的地方

# This means: for category ItOpsLogger (and children), set INFO level by default
# and append to ITOPSLOG
log4j.category.ItOpsLogger=INFO, ITOPSLOG

我猜你可能想使用类似的东西：

# By default, set INFO level and append to FILE and DAILY
log4j.rootCategory=INFO, FILE, DAILY
