问题日志

SLF4J: Class path contains multiple SLF4J bindings.
SLF4J: Found binding in [jar:file:/home/noc/nocserver/./lib/logback-classic-1.1.11.jar!/org/slf4j/impl/StaticLoggerBinder.class]
SLF4J: Found binding in [jar:file:/home/noc/nocserver/lib/logback-classic-1.1.11.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]

lib下slf4j相关包

./jcl-over-slf4j-1.7.25.jar
./jul-to-slf4j-1.7.25.jar
./log4j-over-slf4j-1.7.25.jar
./slf4j-api-1.7.25.jar

貌似也没有冲突呀
