nested exception is org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'sessionFactory' defined in class path resource [spring-config.xml]: Invocation of init method failed; nested exception is org.hibernate.HibernateException: Unable to instantiate default tuplizer [org.hibernate.tuple.component.PojoComponentTuplizer]

应该是sessionFactory配置错了。Invocation of init method failed

看了半天应该是没有问题的，原来我连接的是mysql，现在要连接sqlserver2005了，结果映射了一张表，改了下配置文件就出错了。
