    public void insert(Person person) {
//      this.getHibernateTemplate().save(person);
        this.getSession().save(person);
        this.getSession().beginTransaction().commit();
    }

    public List query() {
        List all=null;

        Query q=this.getSession().createQuery(hql);

    public List queryByName(String name) {
        List all=null;
        String hql="FROM com.zxw.vo.Person AS p WHERE p.name=?";
        Query q=this.getSession().createQuery(hql);
        q.setString(0,name);
        all=q.list();
        return all;
    }

}

用 this.getHibernateTemplate().save(person);
能存入数据库

用this.getSession().save(person);
运行没反应 也不搞错

Answer 1

1. 你自己配置的使用hibernatetemplate。
2. 使用session，就把dao注入sessionFactory。 两种只需要一种就行了。 使用 hibernate template 是不需要继承 Spring提供的 dao 接口的。
