Method passes an incorrect number of parameters to an SLF4J or Logj2 logging statement

Question

Sonar reports this bug: Correctness - Method passes an incorrect number of parameters to an SLF4J or Slf4j2 logging statement.

log.info("{}", e);

What should i do to fix it? Thanks

If `e` is an `Exception`, you shouldnt use a placeholder (`{}`) at all — Felix, Jun 11 '20 at 10:43
None. Just `log.info("", e)`. Exceptions don't need a placeholder — Felix, Jun 12 '20 at 08:03

I think the correct way is the following code:

log.info("{}", e.getMessage());

The stack trace cannot be recorded in this way. – Andy Xu Jun 12 '20 at 02:05
@Andy Xu You can use `logger.info ("{}", e.printStackTrace ());` to print more information,in fact it is equivalent to `e.printStackTrace ();` – kai.tian Jun 12 '20 at 02:53
