  3 <!-- ========================== 日志输出等级  ================================ -->
  4 <!--   OFF：最高等级, 用于关闭所有日志记录  -->
  5 <!-- FATAL：输出严重级别的消息 -->
  6 <!-- ERROR：输出错误级别的消息 -->
  7 <!--  WARN：输出警告级别的消息 -->
  8 <!--  INFO：输出信息级别的消息 -->
  9 <!-- DEBUG：输出调试级别的消息 -->
 10 <!-- TRACE：输出跟踪级别的消息 -->
 11 <!--   ALL：最低等级, 用于打开所有日志记录 -->
 12 <!-- 只有当输出日期的级别大于或等于为日志配置器配置的日志级别时, 这个方法才会执行. 指定日志器的日志级别, 不同的日志器会实现不同的日志输出方案 -->
 13 
 14 <!-- ========================== 自定义输出格式说明 ================================ -->
 15 <!-- %p 输出优先级，即DEBUG，INFO，WARN，ERROR，FATAL -->
 16 <!-- %r 输出自应用启动到输出该log信息耗费的毫秒数 -->
 17 <!-- %c 输出所属的类目，通常就是所在类的全名 -->
 18 <!-- %t 输出产生该日志事件的线程名 -->
 19 <!-- %n 输出一个回车换行符，Windows平台为“\r\n”，Unix平台为“\n” -->
 20 <!-- %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：2002年10月18日 22：10：28，921 -->
 21 <!-- %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。举例：Testlog4.main(TestLog4.java:10) -->
 22 <!-- ========================================================================== -->
 23 
 24 <!-- ========================== 输出方式说明================================ -->
 25 <!-- Log4j提供的appender有以下几种: -->
 26 <!-- org.apache.log4j.ConsoleAppender(控制台), -->
 27 <!-- org.apache.log4j.FileAppender(文件), -->
 28 <!-- org.apache.log4j.DailyRollingFileAppender(每天产生一个日志文件), -->
 29 <!-- org.apache.log4j.RollingFileAppender(文件大小到达指定尺寸的时候产生一个新的文件), -->
 30 <!-- org.apache.log4j.WriterAppender(将日志信息以流格式发送到任意指定的地方) -->
 31 <!-- ========================================================================== -->
