SLF4J: Actual binding is of type [org.slf4j.impl.SimpleLoggerFactory]
Exception in thread "main" java.lang.IllegalArgumentException: LoggerFactory is not a Logback LoggerContext but Logback is on the classpath. Either remove Logback or the competing implementation (class org.slf4j.impl.SimpleLoggerFactory loaded from file:/C:/Users//.gradle/caches/modules-2/files-2.1/org.slf4j/slf4j-simple/1.7.26/dfb0de47f433c2a37dd44449c88d84b698cd5cf7/slf4j-simple-1.7.26.jar). If you are using WebLogic you will need to add 'org.slf4j' to prefer-application-packages in WEB-INF/weblogic.xml: org.slf4j.impl.SimpleLoggerFactory
idea版本 2018.2.8
解决办法：
build.gradle添加如下代码：
exclude module: 'slf4j-log4j12'
exclude module: 'slf4j-ext'
exclude module: 'log4j'
exclude module: 'slf4j-simple'
