以上是报错信息， 自上午import 了一个同事的项目后，就有了这环境问题，无论运行什么（亲手试了helloworld也不行。。。），控制台都会直接报这个错。。。有经验的朋友可以发表一下高见。。。
------解决方案--------------------
你查查配置文件 应该是配置文件的问题
------解决方案--------------------
hibernate.properties not found
org.hibernate.HibernateException: The dialect was not set. Set the property hibernate.dialect.
你使用了hbm2ddl配置，也就是通过实体类hbm.xml文件生成数据库表的功能，但没有配置hibernate.dialect，所以创建数据库表失败，我用的Oracle10g，在hibernate.properties中配置如下：
hibernate.dialect=org.hibernate.dialect.Oracle10gDialect
