java基础-典型的log4j配置
log4j.rootLogger=debug,console
log4j.appender.logfile.encoding=UTF-8
log4j.appender.console=org.apache.log4j.ConsoleAppender
log4j.appender.console.layout=org.apache.log4j.PatternLayout
log4j.appender.console.layout.ConversionPattern=%d{yyy-MM-dd HH:mm:ss } %L %-5p %c - %m%n

log4j.logger.com.xxx.framework.hessian=debug,boss_service_logfile

log4j.appender.boss_service_logfile=org.apache.log4j.RollingFileAppender
log4j.appender.boss_service_logfile.File=../logs/xxx_service.log
log4j.appender.boss_service_logfile.MaxFileSize=10000kb
log4j.appender.boss_service_logfile.MaxBackupIndex=10
log4j.appender.boss_service_logfile.layout=org.apache.log4j.PatternLayout
log4j.appender.boss_service_logfile.layout.ConversionPattern=%d{yyy-MM-dd HH:mm:ss} %-5p - %m%n

我们可以依此类推，配置不同package(com.xxx.framework.hessian)下面的打点日志。
