# Log4j configuration file.
log4j.rootCategory=DEBUG, Default, X //設置log的等級debug，這樣的話所有級別的log信息都被輸出。
假如爲info的話那>=info級別得都被輸出（info,warn,error,fatal）(debug被忽略)。後面的default，X是使用那幾個appender，這裏用了兩個，象Y,R就沒有用到，這裏就沒有效。
log4j.logger.com.fsillc.remote.server=DEBUG, R //server包裏面的所有類使用R這個appender
log4j.logger.com.fsillc.remote.server.CalculatorImplementation=DEBUG, Y //CalculatorImplementation這個類使用Y,
# Available levels are DEBUG, INFO, WARN, ERROR, FATAL
