类 ConsoleHandler

java.lang.Object

java.util.logging.Handler

java.util.logging.StreamHandler

java.util.logging.ConsoleHandler

public class ConsoleHandler
extends StreamHandler

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

构造器详细资料

ConsoleHandler

public ConsoleHandler()

Create a ConsoleHandler for System.err.

The ConsoleHandler is configured based on LogManager properties (or their default values).

方法详细资料

publish

public void publish(LogRecord record)

Publish a LogRecord.

The logging request was made initially to a Logger object, which initialized the LogRecord and forwarded it here.

覆盖:

publish 在类中 StreamHandler

参数:

record - description of the log event. A null record is silently ignored and is not published

close

public void close()

Override StreamHandler.close to do a flush but not to close the output stream. That is, we do not close System.err.

覆盖:

close 在类中 StreamHandler
