warn
Lazy add a log message if isWarnEnabled is true
Lazy add a log message with throwable payload if isWarnEnabled is true
Log a message at the WARN level.
Parameters
the message string to be logged
Log a message at the WARN level according to the specified format and argument.
This form avoids superfluous object creation when the logger is disabled for the WARN level.
Parameters
the format string
the argument
Log a message at the WARN level according to the specified format and arguments.
This form avoids superfluous string concatenation when the logger is disabled for the WARN level. However, this variant incurs the hidden (and relatively small) cost of creating an Object[] before invoking the method, even if this logger is disabled for WARN. The variants taking .warn and .warn arguments exist solely in order to avoid this hidden cost.
Parameters
the format string
a list of 3 or more arguments
