Logback: how to change log directory from "tomcat/bin" to application related?
Solution 1
Well, I solved my problem but it is not very good solution (by my opinion).
First of all I put absolute path to log file in .property file. For example:
logback.log.location=d:\Tomcat\tomcat_8.0.0-RC5\webapps\module\logs
Then I use that property in my logback.xml:
<configuration>
<property file="src\main\resources\system_config.properties" />
<appender name="FILE-MODULE" class="ch.qos.logback.core.FileAppender">
<file>${logback.log.location}\module.log</file>
<encoder>
<pattern>
%date %level [%thread] %logger{10} [%file:%line] %msg%n
</pattern>
</encoder>
</appender>
<logger name="module" level="debug" additivity="false">
<appender-ref ref="FILE-MODULE" />
</logger>
</configuration>
More details you can see here. This is an example, that I use.
But in solution above we have environment specific absolute path to the logs. This is ugly. Of course, we can use system variable CATALINA_HOME to avoid absolute path. But, as I know, CATALINA_HOME can be undefined. Or, we can use another instance of tomcat, that is not in CATALINA_HOME.
Maybe someone have more nice solution that will be environment independent?
UPDATE
Another solution:
Just use relative (to tomcat\bin) path instead absolute in logback.xml:
<configuration>
<appender name="FILE-MODULE" class="ch.qos.logback.core.FileAppender">
<file>..\webapps\module\module.log</file>
<encoder>
<pattern>
%date %level [%thread] %logger{10} [%file:%line] %msg%n
</pattern>
</encoder>
</appender>
<logger name="module" level="debug" additivity="false">
<appender-ref ref="FILE-MODULE" />
</logger>
</configuration>
It was the first idea, that I try to implement. I don't know, why it didn't work before. Maybe there were other problems. Moreover this and this articles confused me.
But now this solution work fine. This is exactly that I am looking for =)
Solution 2
If you do not want to save your logs in Tomcat's bin folder then use ${catalina.base}
as file path prefix in logback.xml file.
<file>${catalina.base}/logs/log.log</file>
Here log file will be saved in existing logs folder of Tomcat instead of bin.

I want to use slf4j with logback for logging.
You can see my logback.xml below:
<configuration> <appender name="FILE-MODULE" class="ch.qos.logback.core.FileAppender"> <file>module.log</file> <encoder> <pattern> %date %level [%thread] %logger{10} [%file:%line] %msg%n </pattern> </encoder> </appender> <logger name="module" level="debug" additivity="false"> <appender-ref ref="FILE-MODULE" /> </logger> </configuration>
The problem is: when I deploy my application to Tomcat, log file is stored in tomcat/bin folder, and I want to store it in myapp folder (tomcat/webapp/myapp).
How can I do that?
