今天初次学习Hibernate，按照指导做的时候，出现如下错误：

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
    at org.slf4j.LoggerFactory.getSingleton(LoggerFactory.java:223)
    at org.slf4j.LoggerFactory.bind(LoggerFactory.java:120)
    at org.slf4j.LoggerFactory.performInitialization(LoggerFactory.java:111)
    at org.slf4j.LoggerFactory.getILoggerFactory(LoggerFactory.java:269)
    at org.slf4j.LoggerFactory.getLogger(LoggerFactory.java:242)

    at org.hibernate.cfg.Configuration.(Configuration.java:152)
    at com.jiang.hibernate.Base.main(Base.java:25)

问题的原因是无法找到org.slf4j.impl.StaticLoggerBinder，我找了一下，确实没有该类，网上搜了一下下面是官方的解答http://www.slf4j.org/codes.html#StaticLoggerBinder：

This error is reported when the org.slf4j.impl.StaticLoggerBinder class could not be loaded into memory. This happens when no appropriate SLF4J binding could be found on the class path. Placing one (and only one) of slf4j-nop.jar, slf4j-simple.jar, slf4j-log4j12.jar, slf4j-jdk14.jar or logback-classic.jar on the class path should solve the problem.

You can download SLF4J bindings from the project download page.

大意是org.slf4j.impl.StaticLoggerBinder 无法载入到内存，原因是没有找到合适的绑定SLF4J，需要添加所列举的包中的某一个。

解决方法如下：

下载slf4j-nop.jar，添加到路径中，就解决问题了
