DEBUG < INFO < WARN < ERROR < FATAL

# level : 是日志记录的优先级，分为 OFF、FATAL、ERROR、WARN、INFO、DEBUG、ALL 或者您定义的级别。Log4j 建议只使用四个级别，优先级从高到低分别是 ERROR、WARN、INFO、DEBUG。通过在这里定义的级别，您可以控制到应用程序中相应级别的日志信息的开关。比如在这里定义了 INFO 级别，则应用程序中所有 DEBUG 级别的日志信息将不被打印出来。

log4j.appender.APPENDER_NAME.file.out.File=${catalina.home}/logs/logs_tomcat.log

%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“\r\n”，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{yyyy MMM dd HH:mm:ss,SSS} ，输出类似： 2002 年 10 月 18 日 22 ： 10 ： 28 ， 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。

log4j.appender.A1.layout.ConversionPattern=%-4r %-5p %d{yyyy-MM-dd HH:mm:ssS} %c %m%n

%p: 输出日志信息优先级，即 DEBUG，INFO，WARN，ERROR，FATAL,
%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
%r: 输出自应用启动到输出该 log 信息耗费的毫秒数
%c: 输出日志信息所属的类目，通常就是所在类的全名
%t: 输出产生该日志事件的线程名
%l: 输出日志事件的发生位置，相当于 %C.%M(%F:%L) 的组合，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)
%x: 输出和当前线程相关联的 NDC（嵌套诊断环境）, 尤其用到像 java servlets 这样的多客户多线程的应用中。
%%: 输出一个"%"字符
%F: 输出日志消息产生时所在的文件名称
%L: 输出代码中的行号
%m: 输出代码中指定的消息，产生的日志具体信息
%n: 输出一个回车换行符，Windows 平台为"\r\n"，Unix 平台为"\n"输出日志信息换行
