Hello Michael, SLF4J does not allow one to close appenders. Moreover, there is no plan to add such capability. I am afraid you will have to write one or two lines of framework specific code in your application. On 29/09/2010 5:23 PM, Michael Schall wrote:

We are in the process of moving from log4j to logback. One requirement placed on me is to be able to revert back to log4j if something "goes wrong". I was hoping that using SLF4J would give me this ability.
I'm trying to achieve writing code only using SLF4J and...
if slf4j-log4j12-1.6.1.jar and log4j-1.2.15.jar are in my production classpath, I'm logging using log4j. If log4j-over-slf4j-1.6.1.jar (for third-party logging), logback-classic-0.9.24.jar, and logback-core-0.9.24.jar are in my production classpath, I'm logging using logback.
So without changing code, I can switch between logging back ends.
Should ILoggerFactory have a shutdown or stop method? It could shutdown whatever logging back end I'm using?
For log4j it would call - org.apache.log4j.LogManager.getLoggerRepository().shutdown(); For logback it would call - loggerContext.stop()
Thoughts? Mike

How about LoggerContext.stop()? It looks as if it's designed specifically for this purpose. It recursively stops and detaches all appenders, amongst other things.
(You can cast the result of LoggerFactory.getILoggerFactory() to a LoggerContext).

I'm using file appenders. At a certain point in my app, a little before shutdown, I have to close all loggers.
How do I tell logback to call stop() on all appenders?
