#%m 输出代码中指定的消息  
#%p 输出优先级，即DEBUG，INFO，WARN，ERROR，FATAL  
#%r 输出自应用启动到输出该log信息耗费的毫秒数  
#%c 输出所属的类目，通常就是所在类的全名  
#%t 输出产生该日志事件的线程名  
#%n 输出一个回车换行符，Windows平台为“rn”，Unix平台为“n”  
#%d 输出日志时间点的日期或时间，默认格式为ISO8601，也可以在其后指定格式，比如：%d{yyy MMM dd HH:mm:ss,SSS}，输出类似：2010年12月31日 20：10：29，921  #%l 输出日志事件的发生位置，包括类目名、发生的线程，以及在代码中的行数。
