[DISCUSS] Used JAVA Lambda Optimized log printing
Hi Community
It is very appropriate to use the delayed nature of lambda expressions to
print logs.
If we should print logs, like this : `log.error("hello world"); `
If log level not config is ERROR, This `Java String` is a loss to the
program.
Now if we used lambda expressions, like this : `log.error(() -> "hello
world ")`
It will only output if the log config is ERROR.
Based on the above considerations, I created
`org.apache.shenyu.common.utils.LogUtils`
This `LogUtils` use lambda expressions to print logs.
In the shenyu project, should we use it all for printing logs?
Looking forward to your suggestions!
Thanks!

HI
its good job，I suggest that we start by using LogUtils.

Hi,Logback has been used in the Shenyu project to record logs, and slf4j
has not been maintained for a long time. I think I can replace these with
`LogUtils`
