确实是文件配置有误，但是你不贴出配置文件，又怎么知道，你哪里配置错误了？，工厂没有配置成功

检查下配置文件，参考前人的经验如下：http://www.cnblogs.com/chuyuhuashi/archive/2012/03/29/2423235.html

Error creating bean with name 'sessionFactory' defined in ServletContext resource [/WEB-INF/classes/applicationContext.xml]

把你的applicationContext.xml的内容贴上来

看不懂啦咯啦咯啦咯啦咯了

applicationContext.xml出问题了，吧他贴出来
