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:
SLF4J: Failed to load class "org.slf4j.impl.StaticLoggerBinder".
SLF4J: See http://www.slf4j.org/codes.html#StaticLoggerBinder for further details.

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。
解决办法,两步:
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
