Prevent specific exceptions loggin in Grails

Question

In grails I want to stop logging some specific exceptions occouring in my controllers.

I have managed this exception with urlmapping to render a custome warning page

Es my url mapping

"500"(controller:'error', action:'excOne', exception: MyExceptionOne)       
"500"(controller:'error', action:'excTwo', exception: MyExceptionTwo)

But this exceptions continued to be logged by log4j. How I can exclude them from logging?

This is my log4j config:

log4j = {
      error  'org.codehaus.groovy.grails.web.servlet',  //  controllers
        'org.codehaus.groovy.grails.web.pages', //  GSP
        'org.codehaus.groovy.grails.web.sitemesh', //  layouts
        'org.codehaus.groovy.grails.commons', // core / classloading
        'org.codehaus.groovy.grails.plugins', // plugins
        'org.codehaus.groovy.grails.orm.hibernate', // hibernate integration
        'org.springframework',
        'org.hibernate',
        'net.sf.ehcache.hibernate',
        'grails.app.services.org.grails.plugin.resource',
        'grails.app.taglib.org.grails.plugin.resource',
        'grails.app.resourceMappers.org.grails.plugin.resource',
        'grails.app.services.NavigationService'


    warn   'org.mortbay.log'    
    debug  "com.myproject.*"

    debug  "grails.app"
    debug  "com.myproject.*"

appenders {
console name:'stdout', layout:pattern(conversionPattern: '[%r] %c{2} %m%n')
}

root {
error 'stdout'
warn 'stdout'
additivity = true
} 

}

Have you ever managed to solve this? – Tobia Oct 01 '14 at 09:32 — Tobia, Oct 01 '14 at 09:32

I have not managed to remove all mentions of the exception in the log, but what I have done is I prevented the stack trace from cluttering up the logs:

Create a StackTracePrinter implementation that behaves the way you want.

package com.myStuff
import org.codehaus.groovy.grails.exceptions.DefaultStackTracePrinter

class MyStackTracePrinter extends DefaultStackTracePrinter {

  String prettyPrint(Throwable throwable) {
    if (throwable instanceof MyException) return "<stack trace suppressed>"
    return super.prettyPrint(throwable)
  }
}

Then, in Config.groovy:

grails.logging.stackTracePrinterClass = 'com.myStuff.MyStackTracePrinter'

Try:

off "your.class.file"

After the line of code:

debug  "com.myproject.*"

Just make sure you provide correct path of your class, let me know the class file path if this doesn't work?

"your.class.file" is the class the throw the exception or the exception class itself? – Fabiano Taioli Mar 25 '13 at 08:20
Where the log statement is written. – mehmood Mar 26 '13 at 13:15
is not what I want... I want do exclude by exception class non by class where the log statement is writen – Fabiano Taioli Mar 26 '13 at 13:50
