%A - Local IP address，本地ip
%b - Bytes sent, excluding HTTP headers, or '-' if no bytes were sent
%B - Bytes sent, excluding HTTP headers
%h - Remote host name (or IP address if enableLookups for the connector is false)，远程主机名称(如果resolveHosts为false则展示IP)
%H - Request protocol，请求协议
%l - Remote logical username from identd (always returns '-')
%m - Request method，请求方法（GET，POST）
%p - Local port，接受请求的本地端口
%q - Query string (prepended with a '?' if it exists, otherwise an empty string
%r - First line of the request，HTTP请求的第一行（包括请求方法，请求的URI）
%s - HTTP status code of the response，HTTP的响应代码，如：200,404
%S - User session ID
%t - Date and time, in Common Log Format format，日期和时间，Common Log Format格式
%u - Remote user that was authenticated
%U - Requested URL path
%v - Local server name
%D - Time taken to process the request, in millis，处理请求的时间，单位毫秒
%T - Time taken to process the request, in seconds，处理请求的时间，单位秒
%I - current Request thread name (can compare later with stacktraces)，当前请求的线程名，可以和打印的log对比查找问题

springboot下的accesslog

yml
