【问题描述】
SLF4J: Class path contains multiple SLF4J bindings.
SLF4J: Found binding in [jar:file:/E:/workstation/***/IMServer/openfire_src/target/openfire/lib/slf4j-log4j12.jar!/org/slf4j/impl/StaticLoggerBinder.class]
SLF4J: See http://www.slf4j.org/codes.html#multiple_bindings for an explanation.
【解决方案】
字面看是jar重复引用了,将E:/workstation/***/IMServer/openfire_src/target/openfire/lib/slf4j-log4j12.jar这个路径下的给删掉就正常了。
