解决错误：Exception in thread "main" java.lang.NoClassDefFoundError: org/sl

解决异常：Exception in thread "main" java.lang.NoClassDefFoundError: org/slf4j/impl/StaticLoggerBinder
学习Hibernate的时候，测试出现：

SLF4J: Failed to load class "org.slf4j.impl.StaticLoggerBinder".
SLF4J: See http://www.slf4j.org/codes.html#StaticLoggerBinder for further details.
Exception in thread "main" java.lang.NoClassDefFoundError: org/slf4j/impl/StaticLoggerBinder

原来是缺少两个jar包：slf4j-log4j12-1.5.0.jar，log4j-1.2.15.jar，lib库里没有集成，得单独去下载。
