Class SimpleLog

java.lang.Object

org.apache.commons.logging.impl.SimpleLog

All Implemented Interfaces:

Serializable, Log

public class SimpleLog
extends Object
implements Log, Serializable

Simple implementation of Log that sends all enabled log messages, for all defined loggers, to System.err. The following system properties are supported to configure the behavior of this logger:

• org.apache.commons.logging.simplelog.defaultlog - Default logging detail level for all instances of SimpleLog. Must be one of ("trace", "debug", "info", "warn", "error", or "fatal"). If not specified, defaults to "info".
• org.apache.commons.logging.simplelog.log.xxxxx - Logging detail level for a SimpleLog instance named "xxxxx". Must be one of ("trace", "debug", "info", "warn", "error", or "fatal"). If not specified, the default logging detail level is used.
• org.apache.commons.logging.simplelog.showlogname - Set to true if you want the Log instance name to be included in output messages. Defaults to false.
• org.apache.commons.logging.simplelog.showShortLogname - Set to * true if you want the last component of the name to be included in output messages. Defaults to true.
• org.apache.commons.logging.simplelog.showdatetime - Set to true if you want the current date and time to be included in output messages. Default is false.
• org.apache.commons.logging.simplelog.dateTimeFormat - The date and time format to be used in the output messages. The pattern describing the date and time format is the same that is used in java.text.SimpleDateFormat. If the format is not specified or is invalid, the default format is used. The default format is yyyy/MM/dd HH:mm:ss:SSS zzz.

In addition to looking for system properties with the names specified above, this implementation also checks for a class loader resource named "simplelog.properties", and includes any matching definitions from this resource (if it exists).
