      org.kuali.rice.core.config.logging.Log4jLifeCycle

All Implemented Interfaces:

Lifecycle

public class Log4jLifeCycle
extends BaseLifecycle

Lifecycle implementation that initializes and shuts down Log4J logging

Nested Class Summary

private static class	Log4jLifeCycle.WorkflowLog4j_1_2_13_Configurer Subclasses the Spring Log4jConfigurer to expose a static method which accepts an initial set of properties (to use for variable substitution)
(package private) static class	Log4jLifeCycle.WorkflowLog4j_1_2_13_PropertyConfigurator Subclasses the Log4j 1.2.13 PropertyConfigurator to add a static method which accepts an initial set of properties (to use for variable substitution)

Field Summary

private static String	AUTOMATIC_LOGGING_CONFIG_URL Location of default/automatic Log4J configuration properties, in Spring ResourceUtils resource/url syntax
private static int	DEFAULT_RELOAD_INTERVAL Default settings reload interval to use in the case that the settings are reloadable (i.e.
private org.apache.log4j.Logger	log Non-static and non-final so that it can be reset after configuration is read
private static String	LOG4J_FILE_NOT_FOUND
private static int	MINUTE Convenience constant representing a minute in milliseconds

Constructor Summary

Log4jLifeCycle()

Method Summary

private boolean	checkPropertiesFileExists(String log4jSettingsPath) Checks if the passed in file exists.
private static String	getLog4jVersion() Uses reflection to attempt to obtain the ImplementationVersion of the org.apache.log4j package from the jar manifest.
