How to filter specific lines from log4j stack trace?

Question

I want to filter specific lines from stack traces using log4j (e.g. net.sf.cglib.* And org.springframework.* ). Is it possible to configure this with log4j ?

In eclipse, the junit plugin allows you to add filters that modify the stack traces displayed on the junit tab, but this does not change the stack traces displayed on the console.

Answer 1

Use this log4j add-on filtering layout: http://www.openmindlab.com/lab/tools/openutilslog4j/layout.html

They have an example with log4j.xml on this page. Just use it.openutils.log4j.FilteredPatternLayout instead of log4j PatternLayout and then put some entries like

  <param name="Filter" value="net.sf.cglib"/> <param name="Filter" value="org.springframework"/> 

below.

I just published an open source library that filters stack trace very well. Here is a link to a small article on the library: MgntUtils open source Java library. There is also a link to sources on github: https://github.com/michaelgantman/Mgnt, and here is a Maven link to the library.
