使用:log4j-1.2.16.jar时在Tomcat启动时控制台有如下错误:

log4j:WARN No appenders could be found for logger (org.springframework.web.context.ContextLoader).
log4j:WARN Please initialize the log4j system properly.
log4j:WARN See http://logging.apache.org/log4j/1.2/faq.html#noconfig for more info.

在Tomcat停止时也没有在报如下错误:

log4j:ERROR LogMananger.repositorySelector was null likely due to error in class reloading, using NOPLoggerRepository

使用log4j-1.2.14.jar时和log4j-1.2.16.jar效果一样,但在Tomcat启动时只报了二句错误:

log4j:WARN No appenders could be found for logger (org.springframework.web.context.ContextLoader).
log4j:WARN Please initialize the log4j system properly.

之后还是不能去掉在Tomcat启动时控制台出现的错误:

log4j:WARN No appenders could be found for logger (org.springframework.web.context.ContextLoader).
log4j:WARN Please initialize the log4j system properly.

最后还是决定使用log4j-1.2.14.jar
