spring boot Tomcat访问日志

1.Tomcat设置访问日志

<Host name="localhost"  appBase="webapps"
            unpackWARs="true" autoDeploy="true">
        <!--
        <Valve className="org.apache.catalina.valves.AccessLogValve" directory="logs"
               prefix="localhost_access_log." suffix=".txt"
               pattern="%h %l %u %t &quot;%r&quot; %s %b" />
        -->
        <Valve className="org.apache.catalina.valves.AccessLogValve" directory="logs"
               prefix="localhost_access_log." suffix=".txt"
               pattern="%h,%l,%u,%t,%T,&quot;%r&quot;,%s,%b,%{Referer}i,&quot;%{User-Agent}i&quot;,%{X-Requested-With}i" 
               fileDateFormat="yyyy-MM-dd.HH"
               />

      </Host>

2.springboot设置访问日志，在properties配置文件中添加tomcat日志配置

#内嵌tomcat日志
server.tomcat.accesslog.buffered=true
server.tomcat.accesslog.directory=/usr/microStorage/tomcatLog
server.tomcat.accesslog.enabled=true
#每天保存一个
server.tomcat.accesslog.file-date-format=yyyy-MM-dd
server.tomcat.accesslog.pattern=%h %l %T %t %r %s %b %{Referer}i %{User-Agent}i
server.tomcat.accesslog.prefix=access_log
server.tomcat.accesslog.rename-on-rotate=false
server.tomcat.accesslog.request-attributes-enabled=false
server.tomcat.accesslog.rotate=true
server.tomcat.accesslog.suffix=.log

3.日志分析，通过正在表达式，将需要分析的信息进行正则捕获提取，然后根据需要进行相关数据的统计及可视化展示

public static void parse() throws Exception{
        String path = "D:/logs/localhost_access_log.2018-09-30.11.txt";
        BufferedReader br = new BufferedReader(new InputStreamReader(new FileInputStream(path)));
        String line = null;
        String reg = "^(.+?),(.+?),(.+?),(.+?),(.+?),(\".+?\"),(.+?),(.+?),(.+?),(\".+?\"),(.+?),(.+?)$";
        Pattern pattern = Pattern.compile(reg);
        while((line=br.readLine())!=null) {
            System.out.println(line);
            Matcher matcher = pattern.matcher(line);
            matcher.matches();
            // pattern="%h,%l,%u,%t,%T,"%r",%s,%b,%{Referer}i,"%{User-Agent}i",%{X-Requested-With}i,%{passport}c" 
            System.out.println("ip="+matcher.group(1));
            System.out.println("date="+matcher.group(4));
            System.out.println("cost="+matcher.group(5));
            System.out.println("request="+matcher.group(6));
            System.out.println("status="+matcher.group(7));
            System.out.println("bytes="+matcher.group(8));
            System.out.println("Referer="+matcher.group(9));
            System.out.println("User-Agent="+matcher.group(10));
            System.out.println("X-Requested-With="+matcher.group(11));
            System.out.println("passport="+matcher.group(12));
            System.out.println("------------------------------------");
        }
        br.close();
    }
