我按照网上配置在tomcat配置了log4j，一部分日志是按我配置那样输出的，但是有一部分日志还是写入catalina.out，不知道为什么，我看了主要是线程调用的类输出的日志。
有谁知道原因吗?
步骤如下：
1. 把log4j-1.2.17.jar，tomcat-juli.jar，tomcat-juli-adapters.jar拷贝到tomcate目录/ lib下
2. 把tomcat-juli.jar拷贝到tomcate目录/ bin下，并覆盖原来的tomcat-juli.jar
3. 在tomcate目录/ lib下（例如/tomcat/apache-tomcat-7.0.59/lib）新建一个文件log4j.properties，并添加如下内容
log4j.rootLogger=INFO, CATALINA
Define all the appenders
log4j.appender.CATALINA=org.apache.log4j.RollingFileAppender
log4j.appender.CATALINA.File=${catalina.base}/logs/catalina.
log4j.appender.CATALINA.MaxFileSize=50MB
log4j.appender.CATALINA.MaxBackupIndex=100
log4j.appender.CATALINA.Append=true
log4j.appender.CATALINA.Encoding=GBK
Roll-over the log once per day
log4j.appender.CATALINA.DatePattern='.'yyyy-MM-dd-HH-mm'.log'
log4j.appender.CATALINA.layout = org.apache.log4j.PatternLayout
log4j.appender.CATALINA.layout.ConversionPattern = %d [%t] %-5p %c- %m%n
log4j.appender.LOCALHOST=org.apache.log4j.DailyRollingFileAppender
log4j.appender.LOCALHOST.File=${catalina.base}/logs/localhost.
log4j.appender.LOCALHOST.Append=true
log4j.appender.LOCALHOST.Encoding=GBK
log4j.appender.LOCALHOST.DatePattern='.'yyyy-MM-dd-HH'.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=${catalina.base}/logs/manager.
log4j.appender.MANAGER.Append=true
log4j.appender.MANAGER.Encoding=GBK
log4j.appender.MANAGER.DatePattern='.'yyyy-MM-dd'.log'
log4j.appender.MANAGER.layout = org.apache.log4j.PatternLayout
log4j.appender.MANAGER.layout.ConversionPattern = %d [%t] %-5p %c- %m%n
log4j.appender.HOST-MANAGER=org.apache.log4j.DailyRollingFileAppender
log4j.appender.HOST-MANAGER.File=${catalina.base}/logs/host-manager.
log4j.appender.HOST-MANAGER.Append=true
log4j.appender.HOST-MANAGER.Encoding=GBK
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=GBK
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
- 在tomcate目录/ conf下（例如/tomcat/apache-tomcat-7.0.59/conf）打开context.xml，把修改为
- 删除 Tomcat 的/tomcat/apache-tomcat-7.0.59/conf/logging.properties 文件（或者重命名-建议）
