日志消息没有写入日志文件

我已经使用Log4j配置了一个项目。我使用log4.properties文件配置了log4j。测试运行时会创建myLog.log文件，但没有任何内容写入日志文件。 Appender我们使用RollingFileAppender和log4j.rootLogger=DEBUG。日志消息没有写入日志文件

任何人都可以提出什么可能会导致此问题？

这里是项目的log4j.properties。

log4j.rootLogger= DEBUG, ConsoleAppender, Rolling 
log4j.appender.ConsoleAppender=org.apache.log4j.ConsoleAppender 
log4j.appender.ConsoleAppender.layout=org.apache.log4j.PatternLayout 

log4j.appender.ConsoleAppender.layout.ConversionPattern=%d %-2p %c.%M(): %m%n 
log4j.appender.Rolling=org.apache.log4j.RollingFileAppender 
log4j.appender.Rolling.MaxFileSize=5MB 
log4j.appender.Rolling.MaxBackupIndex=2 
log4j.appender.Rolling.File=D:\Logs\myProj.log 
log4j.appender.Rolling.layout = org.apache.log4j.PatternLayout 
log4j.appender.Rolling.layout.ConversionPattern=%d %-4p %c.%M(): %m%n 
## Following two lines have been removed now. 
log4j.logger.com=WARN 
log4j.logger.org=WARN

显示的全部内容你'log4j.properties' – adarshr

显示你的log4j.properties –

哪里属性文件和你的Java日志记录代码？ – kgiannakakis

或者更详细：没有来自com或org-packages的日志级别为< WARN的日志记录请求将被启用。所以它不会被转发到你的rootLogger。

引用：

与记录器（或者分配或继承，取其适当）电平Q水平p的日志请求时，如果p> = Q启用。

和

对于给定的记录器每个启用日志记录请求将被转发到所有在该记录器以及层次更高的附加目的地的追加程序。

谢谢它的帮助。但是当我看到日志时，没有任何语句来自我的java类。所有的日志语句都与其他软件包相关。我粘贴了一些日志的问题。之后，我添加了log4j.logger.org.apache.http =错误。现在我在日志中没有看到任何东西。我不知道为什么我的java类中没有一行会记录日志文件。 – PriWeb

@PriWeb - 什么是您使用记录器的类的完全限定名？粘贴如何创建记录器以及您在日志语句中使用的日志级别。 – quaylar

另外：您可以在运行配置中添加“-Dlog4j.debug =”true“”，以查看Log4J如何配置自身（在类路径中是否可能存在其他log4j.properties？） – quaylar

首先，确保你的log4j.properties装入类路径。如果它是一个web应用程序，我认为该文件也可以在WEB-INF/classes目录中找到。但是因为你说这个文件正在创建，我认为这不是问题。

那么，试着用这个

log4j.rootLogger= DEBUG, Console, Rolling 
log4j.appender.Console=org.apache.log4j.ConsoleAppender 
log4j.appender.Console.layout=org.apache.log4j.PatternLayout 

log4j.appender.Console.layout.ConversionPattern=%d %-2p %c.%M(): %m%n 
log4j.appender.Rolling=org.apache.log4j.RollingFileAppender 
log4j.appender.Rolling.MaxFileSize=5MB 
log4j.appender.Rolling.MaxBackupIndex=2 
log4j.appender.Rolling.File=D:\Logs\myProj.log 
log4j.appender.Rolling.layout = org.apache.log4j.PatternLayout 
log4j.appender.Rolling.layout.ConversionPattern=%d %-4p %c.%M(): %m%n

请注意，我已经删除了最后两行。

基本上，这些线路设置日志级别WARN到开始com和org所有软件包。因此，除非您有任何WARN消息被记录，否则在日志文件上根本看不到任何东西。

你可以做这样的事情

log4j.logger.com.foo.bar=DEBUG 
log4j.logger.com.foo.bar.MyClass=TRACE

与试验水平上面会打印记录所有com.foo.bar日志中DEBUG，而将在TRACE级打印com.foo.bar.MyClass日志。

谢谢。这很有帮助。但是当我看到日志时，没有任何语句来自我的java类。所有的日志语句都与其他软件包相关。我正在粘贴问题中的一些日志。 – PriWeb

@PriWeb不禁要问，你有没有在你的课堂上记录任何东西？ – adarshr
