Log4j2升级jar包冲突问题

升级Log4j2后日志提示jar包冲突:

SLF4J: Class path contains multiple SLF4J bindings.
SLF4J: Found binding in [jar:file:/E:/01.work/03.workspace/xxxx/WEB-INF/lib/log4j-slf4j-impl-2.6.2.jar!/org/slf4j/impl/StaticLoggerBinder.class]
SLF4J: Found binding in [jar:file:/E:/01.work/03.workspace/xxxx/WEB-INF/lib/slf4j-log4j12-1.7.7.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 [org.apache.logging.slf4j.Log4jLoggerFactory]

日志显示系统有两个slf4j包。

解决方案:在pom中移除log4j的依赖

<exclusion>
