Question

我已将Tomcat配置为使用log4j记录器，如下所述： https://tomcat.apache.org/tomcat-7.0-doc/logging.html

除了webbapp类的日志记录机制外，一切正常。由于某种原因，它没有记录任何东西......

我遇到以下警告：

 log4j:WARN No appenders could be found for logger (WEBAPP).
 log4j:WARN Please initialize the log4j system properly.

我的log4j.properies（位于$CATALINA_BASE/lib）看起来像这样：

 log4j.rootLogger = INFO,CATALINA,LOCALHOST,CONSOLE,WEBAPP

 # Define all the appenders
 log4j.appender.CATALINA = org.apache.log4j.DailyRollingFileAppender
 log4j.appender.CATALINA.File = ${catalina.base}/logs/catalina
 log4j.appender.CATALINA.Append = true
 log4j.appender.CATALINA.Encoding = UTF-8

 log4j.appender.WEBAPP=org.apache.log4j.RollingFileAppender
 log4j.appender.WEBAPP.File=${catalina.base}/logs/actions
 log4j.appender.WEBAPP.MaxFileSize=4MB
 log4j.appender.WEBAPP.MaxBackupIndex=9
 log4j.appender.WEBAPP.Append = true
 log4j.appender.WEBAPP.Encoding=UTF-8
 log4j.appender.WEBAPP.layout=org.apache.log4j.PatternLayout
 log4j.appender.WEBAPP.layout.ConversionPattern=%d{dd.MM.yyyy - HH:mm:ss} [[%5p] %c [%t]] %m%n
 log4j.category.WEBAPP=INFO
 log4j.additivity.WEBAPP=false

 # Roll-over the log once per day
 log4j.appender.CATALINA.DatePattern = '.'yyyy-MM-dd'.log'
 log4j.appender.CATALINA.layout = org.apache.log4j.PatternLayout
 log4j.appender.CATALINA.layout.ConversionPattern = %d [%t] %-5p %c- %m%n

 log4j.appender.LOCALHOST = org.apache.log4j.DailyRollingFileAppender
 log4j.appender.LOCALHOST.File = ${catalina.base}/logs/localhost
 log4j.appender.LOCALHOST.Append = true
 log4j.appender.LOCALHOST.Encoding = UTF-8
 log4j.appender.LOCALHOST.DatePattern = '.'yyyy-MM-dd'.log'
 log4j.appender.LOCALHOST.layout = org.apache.log4j.PatternLayout
 log4j.appender.LOCALHOST.layout.ConversionPattern = %d [%t] %-5p %c- %m%n

 log4j.appender.MANAGER = org.apache.log4j.DailyRollingFileAppender
 log4j.appender.MANAGER.File = ${catalina.base}/logs/manager
 log4j.appender.MANAGER.Append = true
 log4j.appender.MANAGER.Encoding = UTF-8
 log4j.appender.MANAGER.DatePattern = '.'yyyy-MM-dd'.log'
 log4j.appender.MANAGER.layout = org.apache.log4j.PatternLayout
 log4j.appender.MANAGER.layout.ConversionPattern = %d [%t] %-5p %c- %m%n

 log4j.appender.HOST-MANAGER = org.apache.log4j.DailyRollingFileAppender
 log4j.appender.HOST-MANAGER.File = ${catalina.base}/logs/host-manager
 log4j.appender.HOST-MANAGER.Append = true
 log4j.appender.HOST-MANAGER.Encoding = UTF-8
 log4j.appender.HOST-MANAGER.DatePattern = '.'yyyy-MM-dd'.log'
 log4j.appender.HOST-MANAGER.layout = org.apache.log4j.PatternLayout
 log4j.appender.HOST-MANAGER.layout.ConversionPattern = %d [%t] %-5p %c- %m%n

 log4j.appender.CONSOLE = org.apache.log4j.ConsoleAppender
 log4j.appender.CONSOLE.Encoding = UTF-8
 log4j.appender.CONSOLE.layout = org.apache.log4j.PatternLayout
 log4j.appender.CONSOLE.layout.ConversionPattern = %d [%t] %-5p %c- %m%n

 # Configure which loggers log to which appenders
 log4j.logger.org.apache.catalina.core.ContainerBase.[Catalina].[localhost] = INFO, LOCALHOST
 log4j.logger.org.apache.catalina.core.ContainerBase.[Catalina].[localhost].[/manager] =\INFO, MANAGER
 log4j.logger.org.apache.catalina.core.ContainerBase.[Catalina].[localhost].[/host-manager] =\INFO, HOST-MANAGER

我想在一个名为＆＃39; actions ＆＃39;的特殊日志文件中编写webapp中发生的操作，但是日志文件甚至都没有创建。 webapp在tomcat上运行，除了日志记录之外它工作得很好。在应该登录到日志文件的webapp类中，有一些初始化的记录器：

 private static final Logger LOGGER = LoggerFactory.getLogger("WEBAPP");

我认为这已经足够了但是它还没有工作......

任何建议都会很好，并提前感谢！： - ）

解决了！我刚刚将WEBAPP添加到log4j.category.WEBAPP=INFO。与昏迷分开，现在它终于工作了....

所以，这样做 log4j.category.WEBAPP=INFO, WEBAPP 而不是这个 log4j.category.WEBAPP=INFO 它终于有效了。： - ）

在Tomcat中使用log4j和不同的Appender
