Question：

I'm using import lombok.extern.slf4j.Slf4j; for my class, and here's my log statement:log.info("{} : {} - {}", String1, String2, String3);

But it fails to compile and complaining the above line:java.lang.String cannot be converted to org.slf4j.Marker

Any ideas please?

Answer：

I guess that you are willing to use info(String format, Object... arguments) and are wondering why the method that is really called is info(Marker marker, String format, Object arg1, Object arg2).

As you have exactly four parameters, out of which three matches perfectly, the info(Marker marker, String format, Object arg1, Object arg2) method must be considered as "potentially matching".

You should read the documentation about variable arity parameters to get more details.

It works !
