Class Slf4jLogChute

java.lang.Object
  org.apache.velocity.slf4j.Slf4jLogChute

All Implemented Interfaces:

org.apache.velocity.runtime.log.LogChute

public class Slf4jLogChute
extends Object
implements org.apache.velocity.runtime.log.LogChute

This class was taken from the Velocity SVN since it was not yet released (v 2.0), but needed for integrating Velocity log with slf4j. Redirects Velocity's LogChute messages to SLF4J.

To use, first set up SLF4J, then tell Velocity to use this class for logging by adding the following to your velocity.properties: runtime.log.logsystem.class = org.apache.velocity.slf4j.Slf4jLogChute

You may also set this property to specify what log/name Velocity's messages should be logged to (example below is default). runtime.log.logsystem.slf4j.name = org.apache.velocity

Since:

2.0

Version:

$Id$
