logback - print filename and line number

logback.xml

<configuration>
    <appender name="FILE" class="ch.qos.logback.core.FileAppender">
      <file>myapp.log</file>
      <encoder><pattern>%logger{35} - [%F:%L] - %msg%n</pattern></encoder>
    </appender>

    <appender name="ASYNC" class="ch.qos.logback.classic.AsyncAppender">
      <appender-ref ref="FILE" />
      <!-- add the following line -->
      <includeCallerData>true</includeCallerData>
    </appender>

    <root level="DEBUG"><appender-ref ref="ASYNC" /></root>
 </configuration>

nice

good one for sure, but this process of printing line number and file name is slow , therefor if any one has concern about speed. they may avoid this . reference http://logback.qos.ch/manual/layouts.html

If you use

<pattern>%logger{35} - (%F:%L\) - %msg%n</pattern>

for example in logback-test.xml, it is possible to click on the Filename/Linenumber entry on a unit test output,
to get directly to the location of the source code in IDEs like Intellij.

Example output:

LoggerName - (Main.java:14) - Message
