hibernate中Exception in thread "main" java.lang.ExceptionInInitializerError
晚上用马士兵的hibernate练习项目做了一个导入，但是一直报slf4j错误，后根据视频把jar包引入，
但是又出现了以下错误：
SLF4J: Class path contains multiple SLF4J bindings. SLF4J: Found binding in [jar:file:/D:/Jar%20Package/slf4j-1.6.4/slf4j-log4j12-1.6.4.jar!/org/slf4j/impl/StaticLoggerBinder.class] SLF4J: Found binding in [jar:file:/D:/Jar%20Package/slf4j-1.6.4/slf4j-nop-1.6.4.jar!/org/slf4j/impl/StaticLoggerBinder.class] SLF4J: See http-://www-.slf4j.-org/codes.html#multiple_bindings for an explanation.

真是不知道少了哪个包，很讨厌这种小错误，浪费了一晚上，请朋友们帮分析下。谢谢
看错误貌似是导入包重复了项目可行性研究报告
