How to format date in java logging?

问题

I am using :

log.info("Message");

and the output is:

Jul 8, 2014 12:58:02 PM myclass main
INFO: message

How do i just print the message without the date and INFO: ?

回答1:

Change the format of the SimpleFormatter using the system property:

-Djava.util.logging.SimpleFormatter.format="%2$s: %5$s%6$s%n"

or in the logging.properties:

java.util.logging.SimpleFormatter.format=%2$s: %5$s%6$s%n

All of these properties are documented in the format method.
