SLF4J: Defaulting to no-operation (NOP) logger implementation 报错解决办法

错误提示

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.

原因: log4j 和sl4j的版本不匹配,或是缺少jar包

解决办法: 在pom文件里将相关的jar包换成以下这一组
