SLF4J: Class path contains multiple SLF4J bindings. SLF4J: Found binding in [jar:file:/C:/Users/QianXiao/.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:/C:/Users/QianXiao/.m2/repository/org/slf4j/slf4j-simple/1.7.30/slf4j-simple-1.7.30.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]

　　看着心糟；

其实 大意就是 slf4j 包冲突了 你的系统 有多个 slf4j 包

解决方法就是 去maven 里面找找看slf4j 多余的包 然后 把他 剔除就行了
