log4j配置问题，求教

Question

log4j能配置成按java中不同的package输出日志么？比如com.a和com.b两个package，想让com.a下面的日志输出到一个文件，com.b下面的日子输出到另外一个文件中，请问能不能做到，该怎么配置？求高手解答，小弟感激不尽Log4jJava

配置两个appender，appenderA,appenderB
然后配置你的com.a日志输出为appenderA
com.b日志输出为appenderB
可以参考如下配置文件log4j.rootLogger=debug, console, runtimelog4j.logger.java.sql=debug
