tomcat下添加日志的丁点记录

1、%TOMCAT_HOM%\common\lib下添加两个架包：commons-logging-1.0.4.jar和log4j-1.2.15.jar

2、、%TOMCAT_HOM%\common\classes下添加log4j.properties文件，里面的内容可参考以下：

log4j.rootLogger=info, A1 , R   
log4j.appender.A1=org.apache.log4j.ConsoleAppender    
#log4j.appender.A1.layout=org.apache.log4j.HTMLLayout    
#log4j.appender.A1.layout=org.apache.log4j.SimpleLayout   
log4j.appender.A1.layout=org.apache.log4j.PatternLayout    
log4j.appender.A1.layout.ConversionPattern=%-d{yyyy-MM-dd HH:mm:ss} [%c]-[%p] %m%n    
log4j.appender.R=org.apache.log4j.RollingFileAppender   
log4j.appender.R.File=${myappfuse.root}/WEB-INF/classes/log/log4j.log   
log4j.appender.R.MaxFileSize=200KB   
log4j.appender.R.MaxBackupIndex=100  
log4j.appender.R.layout=org.apache.log4j.PatternLayout   
#log4j.appender.R.layout=org.apache.log4j.DailyRollingFileAppender   
#log4j.appender.R.layout.ConversionPattern=%p -thread: %t - %l - %c - %m%n   
log4j.appender.R.layout.ConversionPattern=%p -%-d{yyyy-MM-dd HH:mm:ss} %l - %m%n   
### set log levels - for more verbose logging change 'info' to 'debug' ###   
#log4j.logger.org.hibernate=info   
#log4j.logger.org.hibernate=debug    
  
### log HQL query parser activity   
#log4j.logger.org.hibernate.hql.ast.AST=debug   
  
### log just the SQL#   
log4j.logger.org.hibernate.SQL=INFO
