springboot 关于 Class path contains multiple SLF4J bindings.警告的解决

工程启动后出现如下警告：

SLF4J: Class path contains multiple SLF4J bindings.
SLF4J: Found binding in [jar:file:/D:/Maven/.m2/repository/ch/qos/logback/logback-classic/1.2.3/logback-classic-1.2.3.jar!/org/slf4j/impl/StaticLoggerBinder.class]
SLF4J: Found binding in [jar:file:/D:/Maven/.m2/repository/org/apache/logging/log4j/log4j-slf4j-impl/2.12.1/log4j-slf4j-impl-2.12.1.jar!/org/slf4j/impl/StaticLoggerBinder.class]
SLF4J: See http://www.slf4j.org/codes.html#multiple_bindings for an explanation.
SLF4J: Actual binding is of type [ch.qos.logback.classic.util.ContextSelectorStaticBinder]

【分析原因】
logback-classic 包和log4j 包，关于org/slf4j/impl/StaticLoggerBinder.class 这个类发生了冲突。

【问题解决】
在idea中打开Maven Projects -> Show Dependencies


在其中搜索冲突的类，这里是logback-classic

这里我们将springboot自带的logging给去掉，右键->Exclude，即可idea会自动在pom文件中将其排除
