本文解决了一个关于Hibernate集成过程中出现的SLF4J日志绑定问题。通过添加Log4J和SLF4J到Log4J适配器的依赖，成功解决了Hibernate无法加载静态日志绑定类的问题。

[b]下载了hibernate-distribution-3.3.1.GA-dist集成到web工程中,运行tomcat服务器,其中报错:
Failed to load class "org.slf4j.impl.StaticLoggerBinder".
详细信息如下:[/b]

================================================================================
[size=large]hibernate工程里面使用的是hibernate3.3.1的Lib。
提示信息中多次提到SLF4J，google了一下，才发现这是现在的Hibernate使用SLF4J API记录日志，所以在Hibernate的lib中，不再提供Log4J的包，而大部分框架依然使用Log4J记录日志，这样导致了兼容性问题。
[b] 解决办法，两步：[/b]

一、在编译路径中添加Log4J的包，比如我一直在用的log4j-1.2.8.jar；

二、再添加一个叫做slf4j-log4j12-1.5.11.jar的包进行转换，注意到这里的log4j12，可能对应的是log4j 1.2版本。

补充：
SLF4J官方下载：http://www.slf4j.org/download.html
下载对应版本后加压找到slf4j-log4j12-XX.jar即可[/size]
