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
