springboot中的access-log

 access-log 用于springboot查看连接数，访问IP、线程号、访问url、返回状态码、访问时间、持续时间
 在以往使用tomcat的过程中。tomcat 是会在logs下打印accesslog 的，来记录请求数，但是springboot内置的tomcat 默认情况下不打开。
 不过一般nignx上打印accesslog，开不开这个也无所谓

accesslog配置


server.tomcat.accesslog.enabled=true 默认是false
server.tomcat.accesslog.buffered=false
server.tomcat.accesslog.directory=E://mall1/logs
server.tomcat.accesslog.prefix=access_log
server.tomcat.accesslog.file-date-format=.yyyy-MM-dd
server.tomcat.accesslog.pattern=%t [%I] %{X-Forwarded-For}i %a %r %q %s (%D ms) //默认值是common
