org.springframework.beans.factory.BeanCreationException

王哥倒过来的整合框架，各种不好使，我深知是自己的问题，上网上找了很多文章

终于找到了问题的所在，但是具体怎么解决我还是没有尝试出来。

一下是错误异常

严重: StandardWrapper.Throwable

org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'sessionFactory' defined in ServletContext resource [/WEB-INF/applicationContext.xml]: Instantiation of bean failed; nested exception is org.springframework.beans.BeanInstantiationException: Could not instantiate bean class [org.springframework.orm.hibernate3.LocalSessionFactoryBean]: Constructor threw exception; nested exception is java.lang.NoClassDefFoundError: org/slf4j/LoggerFactory

网上对此的解释：
该异常产生的原因：
是因为在将spring框架和hibernate框架进行整合的时候，包冲突所引起的，这个bug在myeclipse6.0的时候就开始产生了，产生冲突的两

个.jar文件是：asm.jar和asm-2.2.3.jar的冲突造成的。

解决方案：视频上说删除asm-2.2.3.jar即可正常运行！
但是我在我的机器删除了以后，却一直还是报上面的错：org.springframework.beans.factory.BeanCreationException: Error creating

bean with name 'dataSource' defined in ServletContext resource [/WEB-INF/applicationContext.xml]: Instantiation of bean

failed; nested exception is java.lang.NoClassDefFoundError: org/apache/commons/pool/impl/GenericObjectPool

后来我去我的lib目录下又删除了很多的名字相似的.jar文件（删除了能有5，6个.jar文件）但是还是报上面的错，刺激了！


以上是一位大哥写的，我跟他是一样的，不过后来就是他解决了我没解决- -。！！！

看看明天怎么弄，回来补充~


##昨天下班之前，经理说了，框架就用陪好的就行，一般重复的包都已经删除的了。
大体的意思是解决掉一个包冲突的异常，还会出现第二个。三四五六七八个……

只好按上面大哥说的，删除asm-2.2.3.jar文件，解决asm.jar和asm-2.2.3.jar的冲突。

今天弄出了一个模块的框架，非常高兴，王哥关于这个问题终于给了我个比较合理的答案。

这个问题出在持久层注入的时候有数据写错了，会出现上面的错误。很尴尬啊。。很尴尬啊。。。
