看一下RoutingAppender。也许这可以帮助您入门：
<?xml version="1.0" encoding="UTF-8"?><configuration status="DEBUG" name="MyApp" packages=""> <appenders> <Routing name="Routing"> <Routes pattern="$${ctx:USERNAME}"> <Route> <RollingFile name="user.log" append="true" fileName="users/${ctx:USERNAME}.txt" filePattern="users/archive/${ctx:USERNAME}-%d{MM-dd-yyyy}-%i.txt.gz"> <PatternLayout> <pattern>%d{ISO8601} [%t] %p %c %L - %m%n</pattern> </PatternLayout> <Policies> <TimebasedTriggeringPolicy/> <SizebasedTriggeringPolicy size="50 MB"/> </Policies> </RollingFile> </Route> </Routes> </Routing> </appenders> <loggers> <root level="TRACE"> <appender-ref ref="Routing" level="DEBUG" /> </root> </loggers></configuration>
