why doesn't spring-boot listen to the logging.path variable?

Question

Using spring-boot 1.2.3.RELEASE.

The only way I can get spring-boot to log to a specific directory is by setting the "log.file" property like so:

logging.file=/var/log/app.log

But as far as I can tell, according to the docs, I should be doing:

logging.file=app.log
logging.path=/var/log

But it just doesn't seem to listen to the logging.path property, it will just write the file to the current directory.

Are the docs wrong or is there something really obvious I'm missing here?

Also, with this setting, it's still going to do log rolling properly, right?

Answer 1

From the documentation:

If you want to write log files in addition to the console output you need to set a logging.file or logging.path property

Spring boot considers either file or path property, not both.

This page has all combinations of file and path properties.

Answer 2

Variables path and file can be used simultaneously in the following ways (application.yml):

logging:   path: /var/log/   file: ${logging.path}app.log 

As a result, spring-boot will keep a log in the file /var/log/app.log

Answer 3

using spring 2.4.5

this is work

logging.file.path=./log/
logging.file.name=${logging.file.path}mylog.txt

or

logging.file.name=./log2/mylog.txt

in summary

logging.file.path=.             # write logs to the current directory
logging.file.path=/home/logs    # write logs to /home/logs
logging.file.path=/mnt/logdir   # write logs to /mnt/logdir

for Spring Boot 1.x : set logging.path
