Class Log4jConfigurer

java.lang.Object

org.kuali.ole.sys.context.Log4jConfigurer

public class Log4jConfigurer
extends Object

This configurer serves 2 purposes:
1 - Provide the ability to override the bundled log4j.properties with a custom log4j.properties file
2 - Provide the ability to dynamically alter the log4j configuration at runtime by modifying a log4j.properties on the file system that is being monitored for changes

Unless the property ole.fs.log4j.override is set to true, this configurer takes no action and the default log4j configuration bundled with the application is used.

Method Detail

configureLogging

public static final void configureLogging(boolean doStartupStatsLogging)

If you set the system property -Dlog4j.debug, you will see that the isOverride() method runs code that issues logging statements. This means that log4 has already initialized itself and has issued a few logging statements prior to the point where this method attempts to configure log4j with a custom log4j.properties.

So this method is re-configuring log4j immediately after log4j uses its internal procedures to automatically configure itself.

Kinda funky, but it seems to work ok.

Logging statements issued after this method finishes honor the new settings.

isOverride

protected static boolean isOverride()

Return true if we need to override the default log4j configuration with custom settings. False otherwise

getCustomConfigFile

protected static File getCustomConfigFile()

getReloadMillis

protected static long getReloadMillis()

debugClasspath

protected static void debugClasspath()

getNumberFormatter

protected static NumberFormat getNumberFormatter()
