Multiple formats in logging.properties

Question

I have two handlers in my logging.properties:

handlers = java.util.logging.FileHandler, java.util.logging.ConsoleHandler

Both use the SimpleFormatter:

java.util.logging.FileHandler.formatter = java.util.logging.SimpleFormatter
java.util.logging.ConsoleHandler.formatter = java.util.logging.SimpleFormatter

But now I want two different formats for these handlers. The console handler should print only a short message. The file handler on the other hand should print a more detailed message. But how to use different formats for both formatters? The following did not work:

java.util.logging.FileHandler.formatter.format = ...

And using

java.util.logging.SimpleFormatter.format

below the corresonding formatters did not work either. Any ideas? I don't want to implement own formatters just as a workaround...

Answer 1

The java.util.logging.SimpleFormatter only supports one JVM wide format. If your project includes JavaMail 1.5.2 or later you can use the CompactFormatter on your ConsoleHandler and the SimpleFormatter on your FileHandler.

##logging.properties#
handlers = java.util.logging.FileHandler, java.util.logging.ConsoleHandler
java.util.logging.ConsoleHandler.formatter=com.sun.mail.util.logging.CompactFormatter
com.sun.mail.util.logging.CompactFormatter.format=%4$s: %5$s [%1$tc]%n
java.util.logging.FileHandler.formatter=java.util.logging.SimpleFormatter
java.util.logging.SimpleFormatter.format=%1$tc %2$s%n%4$s: %5$s%6$s%n
