Java Logging statement says Cannot Find Symbol

Question

private static final Logger LOGGER = LoggerFactory.getLogger(Updater.class);

I am using SLF4J and Logback

When I try to log statements

LOGGER.info("{}:{}:{}", one, two, three)

it says

cannot find symbol method info(java.lang.String,java.lang.String,java.lang.String,java.lang.String)

Is there not any way I can log more than two variables in a single info statement?

Answer 1

You must upgrade SLF4J to 1.7 which includes Logger.info(java.lang.String, java.lang.Object...) varargs method. See Bug 31 - Varargs for Logger methods fixed after six years worth of discussion.

Prior to 1.7 you must surround arguments with Object[] if you are using more than two:

LOGGER.info("{}:{}:{}", new Object[] {one, two, three})

Answer 2

You might be using an old version of slf4j.

In previous version you could only log up to 2 parameters in this way, but newer version can take any number of parameters.
