springboot logging file name

Hello. please help with the file name. The time format does not work well.

I expected to see 1 file named "2020-02-07 10_38_40 pid-17996.log"

I don't think you're allowed to use such patterns in the main log file itself. Such patterns are only useful for rolling file names; with Spring Boot 2.2+, you can do something like this:

logging:
  file:
    name: logs/spring.log
  pattern:
    rolling-file-name: "${LOG_FILE}.%d{yyyy-MM-dd}.${PID}.%i.gz"

and have files like this in your logs folder:

spring.log
spring.log.2020-02-07.3457.0.gz
spring.log.2020-02-07.3457.1.gz

In any case, this has more to do with the rolling file policy with the logging system you've chosen. For more questions, please use StackOverflow.

Thanks!
