How to filter stacktrace frames in Logback
I contacted Tomasz Nurkiewicz (the author of the blog linked in the question) and he kindly answered my question. I'm posting the answer, just in case:
While printing stack trace, to filter lines from bar
package use the following:
<configuration>
<appender name="STDOUT" class="ch.qos.logback.core.ConsoleAppender">
<encoder>
<pattern>[%thread] %-5level - %msg%n%rEx{full, bar}</pattern>
</encoder>
</appender>
...
</configuration>
I wanted to use it in my web application (Tomcat+Spring+Hibernate+etc). So I configured logback with the following not to print any stack trace line from org.something
packages (e.g. org.apache
, org.springframework
, org.hibernate
, etc):
<configuration>
<appender name="STDOUT" class="ch.qos.logback.core.ConsoleAppender">
<encoder>
<pattern>[%thread] %-5level - %msg%n%rEx{full, org}</pattern>
</encoder>
</appender>
...
</configuration>
Thanks Tomasz!
This may help someone who is writing springboot apps like me
I am currently using

<encoder>
<pattern>${APP_NAME} %green(%d{dd-MM-yyyy HH:mm:ss.SSS}) %magenta([%thread]) %highlight(%-5level) %red(%logger.%M:%L) - %magenta(%msg) %rEx{full,java.lang.reflect.Method,

I wrote my own feature that filters stacktrace which I used since 2010 and I am very happy with it. I published my own Open Source Java Library called MgntUtils which has stackfiltering feature and some other useful (IMHO) features. Here is the link to maven central MgntUtils and here is a link to github if you want a source code: MgntUtils at github also here is the link to the article that describes the library: MgntUtils Open Source Java library with stack trace filtering, Silent String parsing, Unicode converter and Version comparison. See The paragraph "Stacktrace noise filter"
