Failed to instantiate SLF4J LoggerFactory SLF4J: Class path contains multiple SLF4J bindings.

SLF4J: Class path contains multiple SLF4J bindings.
SLF4J: Found binding in [jar:file:/application/lib/logback-classic-1.2.3.jar!/org/slf4j/impl/StaticLoggerBinder.class]
SLF4J: Found binding in [jar:file:/application/gate2.jar!/BOOT-INF/lib/logback-classic-1.2.3.jar!/org/slf4j/impl/StaticLoggerBinder.class]
SLF4J: See http://www.slf4j.org/codes.html#multiple_bindings for an explanation.
Failed to instantiate SLF4J LoggerFactory
Reported exception:
java.lang.NoClassDefFoundError: org/slf4j/spi/LoggerFactoryBinder

目录结构：

/application/lib/logback-classic-1.2.3.jar

/application/gate2.jar

原因：

执行命令 java -jar /application/gate2.jar .会去找/application/lib/logback-classic-1.2.3.jar导致冲突

结论：

logback-classic-会自动查找当前目录及子目录得相关jar包
