An example: import org.slf4j.Logger; import org.slf4j.LoggerFactory; public class LoggingTest { @Test public void loggingTest() { Logger logger = LoggerFactory.getLogger(this.getClass()); int x = 0xdeadbeef; long y = 0xdeadbeef; try { throw new Exception("This is a mighty exception!"); } catch(Exception e) { logger.error("I wanna log {} and http://stackoverflow.com/questions/17716381/slf4j-parameterized-logging-using-varargs-method {} and {} with backtrace", x, y, 3, e); } } } On the logging method, eclipse produces such a warning: The method error(String, Object, Object) in the type Logger is not applicable for the arguments (String, int, long, int, Exception) and fails to compile. However, if I change the logging call to: logger.error("I wanna log {} and {} and {} with backtrace", new Object[]{x, y, 3, e}); It compiles and runs as expected (logging 3 "variables" and the exception stack trace). The library versions are: slf4j-api-1.7.5.jar, slf4j-log4j12-1.7.5.jar and log4j-1.2.14.jar, if it makes any difference. If anybody would point out the shortcomings of my thinking abilities, it'd be very much appreciated! java slf4j share|improve this question asked Jul 18 '13 at 6:45 Manjabes 1,02211029 You have 3 placeholders in your string but 4 arguments -- is this on purpose? –fge Jul 18 '13 at 6:48 1 Yes: slf4j.org/faq.html#paramException –Manjabes Jul 18 '13 at 6:49 I think this answer explains it very nicely. –mthm Jul 18 '13 at 6:50 Well, according to the FAQ, that the first attempt fails to compile is expected; however, I don't see how the second can work... –fge Jul 18 '13 a
