ssm框架log4j打印sql日志(maven项目)

1.编写log4j.properties配置文件

2.web.xml  配置加载log4j.properties和监听log4j

3.在需要输出日志的类写入配置

log4j.properties

log4j.rootLogger=DEBUG,CONSOLE,A
log4j.addivity.org.apache=false

log4j.appender.CONSOLE=org.apache.log4j.ConsoleAppender
log4j.appender.CONSOLE.Threshold=DEBUG
log4j.appender.CONSOLE.layout.ConversionPattern=%d{yyyy-MM-dd HH\:mm\:ss} -%-4r [%t] %-5p  %x - %m%n
log4j.appender.CONSOLE.Target=System.out
log4j.appender.CONSOLE.Encoding=gbk
log4j.appender.CONSOLE.layout=org.apache.log4j.PatternLayout


log4j.appender.A=org.apache.log4j.DailyRollingFileAppender  
log4j.appender.A.File=${catalina.home}/logs/FH_log/PurePro_
log4j.appender.A.DatePattern=yyyy-MM-dd'.log'
log4j.appender.A.layout=org.apache.log4j.PatternLayout  

log4j.appender.A.layout.ConversionPattern=[FH_sys]  %d{yyyy-MM-dd HH\:mm\:ss} %5p %c{1}\:%L \: %m%n
