在javaWEB项目中使用Log4j2详细方法(不是maven项目)

我需要web.xml配置详解，还有使用的资源jar包，以及log4j2.xml的常用配置

direct log messages to stdout

log4j.appender.stdout=org.apache.log4j.ConsoleAppender
log4j.appender.stdout.Target=System.out
log4j.appender.stdout.layout=org.apache.log4j.PatternLayout
log4j.appender.stdout.layout.ConversionPattern=%d{ABSOLUTE} %5p %c{1}:%L - %m%n

direct messages to file mylog.log

log4j.appender.file=org.apache.log4j.FileAppender
log4j.appender.file.File=c:/mylog.log
log4j.appender.file.layout=org.apache.log4j.PatternLayout
log4j.appender.file.layout.ConversionPattern=%d{ABSOLUTE} %5p %c{1}:%L - %m%n

set log levels - for more verbose logging change 'info' to 'debug'

log4j.rootLogger=info, stdout
