ConsoleHandler

public class ConsoleHandler
extends StreamHandler

java.lang.Object
   ↳ java.util.logging.Handler
     ↳ java.util.logging.StreamHandler
       ↳ java.util.logging.ConsoleHandler


This Handler publishes log records to System.err. By default the SimpleFormatter is used to generate brief summaries.

Configuration: By default each ConsoleHandler is initialized using the following LogManager configuration properties where <handler-name> refers to the fully-qualified class name of the handler. If properties are not defined (or have invalid values) then the specified default values are used.

  • <handler-name>.level specifies the default level for the Handler (defaults to Level.INFO).
  • <handler-name>.filter specifies the name of a Filter class to use (defaults to no Filter).
  • <handler-name>.formatter specifies the name of a Formatter class to use (defaults to java.util.logging.SimpleFormatter).
  • <handler-name>.encoding the name of the character set encoding to use (defaults to the default platform encoding).

For example, the properties for ConsoleHandler would be:

  • java.util.logging.ConsoleHandler.level=INFO
  • java.util.logging.ConsoleHandler.formatter=java.util.logging.SimpleFormatter

For a custom handler, e.g. com.foo.MyHandler, the properties would be:

  • com.foo.MyHandler.level=INFO
  • com.foo.MyHandler.formatter=java.util.logging.SimpleFormatter
