2019独角兽企业重金招聘Python工程师标准>>>

#环境

tomcat 7.0.57.0

#log4j日志设置 ###1. 准备jar包： [log4j 1.2](从 http://www.apache.org/dist/logging/log4j/1.2.17/ )下载 log4j-1.2.17.tar.gz tomcat extras下载JULI adapters jar 以及JULI log4j jar 此处应为对应tomcat7.0.57版本 将 log4j-1.2.17.tar.gz 解压。复制log4j-1.2.17.jar、log4j-1.2.17.jar到 tomcat/lib 目录下 将下载得到的tomcat-juli-adapters.jar复制到tomcat/lib目录下 将获取的tomcat-juli.jar替换tomcat/bin/tomcat-juli.jar

2.修改context.xml

修改 Tomcat 的 conf/context.xml 文件，将为 ###3.创建log4j.properties 在tomcat/lib目录下创建log4j.properties log4j.rootLogger = INFO, CATALINA

# Define all the appenders
log4j.appender.CATALINA = org.apache.log4j.DailyRollingFileAppender
log4j.appender.CATALINA.File = ${catalina.base}/logs/catalina

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.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

###4. 重命名 Tomcat 的 conf/logging.properties 文件;

###5.重启tomcat
