tomcat使用log4j管理日誌

一、JDK+tomcat環境  參考：http://www.cnblogs.com/zzzhfo/p/6444029.html

二、下載相關軟件

log4j下載地址

http://www.apache.org/dist/logging/log4j/

http://www.apache.org/dist/logging/log4j/1.2.17/

http://www.apache.org/dist/logging/log4j/1.2.17/log4j-1.2.17.tar.gz  

三、中止服務

shutdown.sh

•  將log4j.properties和log4j-1.2.17.jar放到tomcat/lib目錄下

配置log4j.properties

這裏方便測試

'.'yyyy-MM-dd-HH-mm'.log'設置爲每分鐘

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.CATALINA.Append = true
log4j.appender.CATALINA.Encoding = UTF-8
# Roll-over the log once per day
log4j.appender.CATALINA.DatePattern = '.'yyyy-MM-dd-HH-mm'.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-HH-mm'.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-HH-mm'.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-HH-mm'.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

 

到官網下載 tomcat-juli.jar和tomcat-juli-adapters.jar包。

https://tomcat.apache.org/

https://tomcat.apache.org/download-70.cgi

http://mirrors.hust.edu.cn/apache/tomcat/tomcat-7/v7.0.77/bin/extras/tomcat-juli-adapters.jar

http://mirrors.hust.edu.cn/apache/tomcat/tomcat-7/v7.0.77/bin/extras/tomcat-juli.jar

 

• 將tomcat-juli-adapters.jar包放到tomcat/lib目錄下
• 將tomcat-juli.jar包放到tomcat/bin目錄下（替換原有的）
• 刪除或重命名tomcat/conf目錄下的logging.properties文件
• 修改tomcat/conf/目錄下context.xml

將<Context>改成<Context swallowOutput="true">

[root@localhost conf]# cat context.xml 
<?xml version='1.0' encoding='utf-8'?>

• 啓動服務

[root@localhost tomcat]# bin/startup.sh 
Using CATALINA_BASE:   /usr/local/tomcat
Using CATALINA_HOME:   /usr/local/tomcat
Using CATALINA_TMPDIR: /usr/local/tomcat/temp
Using JRE_HOME:        /usr/local/jdk1.7.0_79
Using CLASSPATH:       /usr/local/tomcat/bin/bootstrap.jar:/usr/local/tomcat/bin/tomcat-juli.jar
Tomcat started.

 

查看日誌

 首先要訪問本身的工程，讓其產生日誌。

[root@localhost logs]# ls
