java - Date format in tomcat accesslog configuration

Question

My Springboot based web-application is having tomcat configuration like this :

tomcat:
    accesslog:
        pattern: '{
                     "date" : "%t",
                      .
                      .

and so on. Now with this, my tomcat logs are having date printed in a format like this : [24/Feb/2020:14:06:41 +0000] but I want them to be printed in this format : 2020-09-29T18:46:19.330Z

So how can I typecast this date to some other format which tomcat can manage.

Answer 1

To specify another date format you can use %{XXX}t where XXX is any of the format specifications of SimpleDateFormat, e.g. %{dd.MM.yyyy}t.

You'll find the other format tags in Tomcat's documentation.
