spring整合hibernate出现的异常

严重: Exception sending context initialized event to listener instance of class org.springframework.web.context.ContextLoaderListener

这个信息出现的原因有以下可能：
1.配置文件错误（不在多说，自己检查）
2.没有完全整合spring与hibernate框架，在项目中使用了hibernate的ORM映射与hibernate.cfg.xml连接数据库的配置文件如此需要加入hibernate源码jar包。如果不需要hibernate的话，则要将配置文件信息全写在applicationContext.xml文件中或相关文件中。运行后还是报错，则是asm的jar包冲突
