错误信息 :

SLF4J: Class path contains multiple SLF4J bindings.
SLF4J: Found binding in [jar:file:/E:/Maven/repository/org/slf4j/slf4j-log4j12/1.7.26/slf4j-log4j12-1.7.26.jar!/org/slf4j/impl/StaticLoggerBinder.class]
SLF4J: Found binding in [jar:file:/E:/Maven/repository/ch/qos/logback/logback-classic/1.2.3/logback-classic-1.2.3.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.slf4j.impl.Log4jLoggerFactory]
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.Log4jLoggerFactory loaded from file:/E:/Maven/repository/org/slf4j/slf4j-log4j12/1.7.26/slf4j-log4j12-1.7.26.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.Log4jLoggerFactory
	at org.springframework.util.Assert.instanceCheckFailed(Assert.java:655)

解决方案 : 移除 org.slf4j:slf4j-log4j12:1.7.26
