Answer 1

创建bean时，

HibernateTemplate(doc)需要sessionFactory。

<bean id="hibernateTemplate" class="org.springframework.orm.hibernate4.HibernateTemplate">
        <property name="sessionFactory" ref="sessionFactory" />
    </bean>

Answer 2

我认为通过在hibernateTemplate中注入sessionFactory可以解决您的问题。但是你可以完全摆脱hibernateTemplate。尝试以下，对我来说似乎比使用hibernateTemplate

更好

UserDaoImpl文件

package dao;

import org.springframework.beans.factory.annotation.*;
import org.hibernate.SessionFactory;
import org.springframework.stereotype.Repository;

import beans.User;
@Repository
public class UserDaoImpl implements UserDao {

    @Autowired
    private SessionFactory sessionFactory;

    @Override
    public void save(User user) {       
        sessionFactory.getCurrentSession().save(user);
    }
