Spring+hibernate 简单整合代码

1.SessionFatory注入 spring.xml文件

2.SpringHibernateDemo.java文件
package com.po;

import org.springframework.context.ApplicationContext;
import org.springframework.context.support.ClassPathXmlApplicationContext;

public class SpringHibernateDemo
{
 public static void main(String[] args){
  ApplicationContext context = new ClassPathXmlApplicationContext("spring.xml");
  IUserDAO userDAO = (IUserDAO)context.getBean(userDAO);
  User user = new User();
  user.setName("accp");
  user.setAge(new Integer(20));

  userDAO.insert(User);

  user = userDAO.find(new Integer(1));

  System.out.println("name:"+user.getName());
 }
}

3.HibernateTemplate  UserDAO.java文件
package com.po;

import org.hibernate.SessionFactory;
import org.springframework.orm.hibernate3.hibernateTemplate;

public class UserDAO implements IUserDAO
{
 private HibernateTemplate hibernateTemplate;

 public void setSessionFactory(SessionFactory sessionFactory){
  hibernateTemplate = new HibernateTemplate(sessionFactory)
 }
 
 public void insert(User user){
  hibernateTemplate.save(user);
 }

 public User find(Integer id){
  User user = (User) hibernateTemplate.get(User.class,id);
  return user;

 }

}
