上面是错误信息，我会贴出目录结构，以及相应的配置。

user-spring

user-struts

ApplicationContext

stuts

希望各位大神帮忙解答

Answer 1

佟刚的 还是？

Answer 2

好的，您说的方法我稍后试试，谢谢您的解决方案

Answer 3

谢谢您，已经成功解决，看来时我写代码的时候太过疏忽，自己在xml里面找了半天也没解决，大神请手下本小白的膝盖。

Answer 4

你昏头了吧。。。。

很明显，userDAOImpl 应该实现 userDAO 接口，而不是BaseDao<User>接口。

你可以 userDAO extends BaseDao<User>，然后 userDAOImpl extends BaseDAOImpl implements userDAO

Answer 5

public abstract class BaseDaoImpl<T> extends HibernateDaoSupport implements BaseDao<T> {

	Class<T> clazz;
	
	public BaseDaoImpl() {
	     ParameterizedType pt=(ParameterizedType)this.getClass().getGenericSuperclass();//BaseDaoImpl<User>
	    clazz =(Class<T>) pt.getActualTypeArguments()[0];//获取范型类的第一个参数类
	}
	
	@Override
	public void save(T entity) {
		getHibernateTemplate().save(entity);
	}

	@Override
	public void update(T entity) {
		getHibernateTemplate().update(entity);
	}

	@Override
	public void delete(Serializable id) {
		getHibernateTemplate().delete(findObjectById(id));
	}

	@Override
	public T findObjectById(Serializable id) {
		return getHibernateTemplate().get(clazz,id);
	}


	@Override
	public List<T> findObjects() {
		Query query = getSession().createQuery("FROM "+ clazz.getSimpleName());
		return query.list();
	}

	}



	





	
UserDaoImpl

public class UserDaoImpl extends BaseDaoImpl<User> implements BaseDao<User> {

}



		
	

		
	

 
 

Answer 6

我把Dao贴出来给你们看看，谢谢你们的帮助

Answer 7

第一句话说得很清楚了，userDao，你看看是不是像楼上说的那样。

Answer 8

不是的，我是写了一个baseDao ,然后继承，并实现UserDao

Answer 9

你的 userDAOImpl 忘了实现 userDAO 接口了吧。。好好检查下你的代码 

Answer 10

这个地方我该了没用，谢谢您！

Answer 11
