下面我们对“%d %t %p %l %m %n”一一讲解:
l %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{yyyy-MM-dd HH:mm:ss},输出类似:2005-7-19 17:49:27,刚好适合插入SQLServer;
l %t 产生该日志事件的线程名;
l %p 日志的log_level,如DEBUG、WARN或者INFO;
l %c 输出所属的类目,通常就是所在类的全名,如“iNotes.Default”;
l %m 日志的内容;
l %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。如write2database.main(write2database.java:33);
l %n 输出一个回车换行符,Windows平台为“ ”,Unix平台为“ ”
