SLF4J: Failed to load class "org.slf4j.impl.StaticLoggerBinder".
SLF4J: Defaulting to no-operation (NOP) logger implementation
SLF4J: See http://www.slf4j.org/codes.html#StaticLoggerBinder for further details.

slf4j即簡(jiǎn)單日志門面（Simple Logging Facade for Java）瓣喊，不是具體的日志解決方案，它只服務(wù)于各種各樣的日志系統(tǒng)黔酥。 - 打印
slf4j需要具體日志實(shí)現(xiàn)框架log4j,log4j2等 - 第三方框架使用
slf4j方便使用者用自己的日志實(shí)現(xiàn)框架接管日志
寫第三方項(xiàng)目的時(shí)候可以使用日志實(shí)現(xiàn)框架做 Test
這里使用了 log4j2 做日志的實(shí)現(xiàn)框架
scope 設(shè)置了 test 打包的時(shí)候不會(huì)被打包進(jìn)去
