org.springframework.beans.factory.BeanCreationException

严重: Context initialization failed org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'userChoiService' defined in file [C:/tomcat6.0/webapps/Reservationsystem2/WEB-INF/classes/applicationContext-beans.xml]: Invocation of init method failed; nested exception is java.lang.IllegalArgumentException: sessionFactory or hibernateTemplate is required Caused by: java.lang.IllegalArgumentException: sessionFactory or hibernateTemplate is required at org.springframework.orm.hibernate3.support.HibernateDaoSupport.checkDaoConfig(HibernateDaoSupport.java:112) at org.springframework.dao.support.DaoSupport.afterPropertiesSet(DaoSupport.java:44) at org.springframework.beans.factory.support.AbstractAutowireCapableBeanFactory.invokeInitMethods(AbstractAutowireCapableBeanFactory.java:1062) 原因：在写userchoiserviceimpl时由于是复制Dao包下的文件，所以很粗心的把extends HibernateDaoSupport 也copy过去了修改方法：1去掉、extends HibernateDaoSupport 就可以了； 2、 在bean里加入(这个没试过）。
