[slf4j-dev] Add Supplier args methods for Logger on java 8.

[Federico Fissore]

Support for lazy arguments evaluation should be part of slf4j 2.0

https://github.com/qos-ch/slf4j/pull/203

If you want to have it with current slf4j 1.x you can give slf4j-fluent 
a try

> New:
> 
> log.info("INFO a {} b {}",()->JsonUtil.ObjectToJson(instance),"success");

> The new one with better performance because the ObjectToJson called only

> I found slf4j support jdk version older the 8. Maybe we can create a new
