程序可以执行流程正确，没有错误。可以到达最终的页面。
但update的语句好像并没有执行。控制台没有任何输出。db中也没有删掉。
把下面的update语句换成select * from user则完全正常。
如果解决，200分相送。
多谢。
下面给出完整的代码：：
controller如下
public class DeleteUserController implements Controller {
private UserDeleteDAO delDao;
public ModelAndView handleRequest(HttpServletRequest request,
HttpServletResponse response) throws Exception {
delDao.deleteUser(new Integer(2));
return new ModelAndView("success.jsp");
}
public UserDeleteDAO getDelDao() {
return delDao;
}
public void setDelDao(UserDeleteDAO delDao) {
this.delDao = delDao;
}
}
实现的bean如下::
public class UserDeleteDAOImpl extends HibernateDaoSupport implements
UserDeleteDAO {
public void deleteUser(final Integer id) {
getHibernateTemplate().execute(new HibernateCallback() {
public Object doInHibernate(Session session) {
Query query = session.createQuery("delete from user where id = :id");
query.setInteger("id", id.intValue());
System.out.println(id.intValue());
System.out.println("删除");
return null;
}
});
}
}
xml如下::
