Question

我正在尝试学习spring 3和DAO和BO类以及如何使用它进行自动装配，我想知道这是连接sessionFactory的正确方法，因为我已经读过它最好使用

public void save(Customer customer) {
    sessionFactory.getCurrentSession().save(customer);
}

而不是

public void save(Customer customer){
    getHibernateTemplate().save(customer);
}

以下是连接sessionFactory的正确方法吗？

CustomHibernateDaoSupport类

package com.fexco.helloworld.web.util;

import org.hibernate.SessionFactory;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.beans.factory.annotation.Qualifier;
import org.springframework.orm.hibernate3.support.HibernateDaoSupport;

public abstract class CustomHibernateDaoSupport extends HibernateDaoSupport
{    
@Autowired
@Qualifier("sessionFactory")
public void seSessionFactory(SessionFactory sessionFactory) {

    this.setSessionFactory(sessionFactory);
}
}

CustomerDaoImpl类

package com.fexco.helloworld.web.dao;

import java.util.List;

import org.hibernate.SessionFactory;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Repository;
import com.fexco.helloworld.web.model.Customer;
import com.fexco.helloworld.web.util.CustomHibernateDaoSupport;

@Repository("customerDao")
public class CustomerDaoImpl extends CustomHibernateDaoSupport implements CustomerDao{


@Autowired
private SessionFactory sessionFactory;

public void save(Customer customer) {
    sessionFactory.getCurrentSession().save(customer);
}

这是正确的还是我在某个地方犯了错误，因为我无法让它发挥作用？感谢

以下解释了为什么我们不需要Hibernate 3的任何模板 http://blog.springsource.com/2007/06/26/so-should-you-still-use-springs-hibernatetemplate-andor-jpatemplate/

正确使用sessionFactory的方法
