Answer 1

org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'sessionFactory' defined in class path resource [applicationContext.xml]: Invocation of init method failed; 在类路径资源里错误的sessionFactory定义
spring的配置文件applicationContext.xml初始化失败。应该是路径问题。你再看看下。最好问问题的时候，说明错误原因，不要一上来就发这东西，谁看都烦。

Answer 2

把这个applicationContext.xml 贴出来，问问题不要全是对码或全是错误，加几个字说明一下,并把相应的原码贴出来...

Answer 3

包冲突的，一般都是hibernate里面的包和spring的包冲突
