Connected to the target VM, address: '127.0.0.1:59220', transport: 'socket'
    SLF4J: Class path contains multiple SLF4J bindings.
    SLF4J: Found binding in [jar:file:/C:/Users/user/.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/user/.m2/repository/org/slf4j/slf4j-simple/1.7.25/slf4j-simple-1.7.25.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]

spring boot 出现这个问题，就是因为log4j的依赖包产生了冲突，根据提示删除一个jar包即可。

[jar:file:/C:/Users/user/.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/user/.m2/repository/org/slf4j/slf4j-simple/1.7.25/slf4j-simple-1.7.25.jar!/org/slf4j/impl/StaticLoggerBinder.class]

这是关键信息，找到对应位置的jar包删除即可。

但是删除jar后还是报错，IDEA会自动下载jar包，应该就是jar包冲突的问题，后来找到冲突的原因，排除即可：
