Spring和Hibernate整合开发

想的很复杂,用起来就那么回事.

怎么回事呢???

就是把hibernate的配置

dataSource    ----org.apache.commons.dbcp.BasicDataSource

sessionFactory  -----org.springframework.orm.hibernate3.LocalSessionFactoryBean

交给Spring去管理.

spring再管理自己的事务,bean等.

配置好spring,加入jar文件,

加入hibernate的jar文件.

加入数据库jar.







先看看配置文件,强烈建议复制,手动写我就出错了.最后还是复制别人现成的.

注解先要找开哦.

再写那个Person bean文件PO,映射文件,这是基本的,写不出来,就不用看了.

再写那个服务类的接口,这个也是每个类公用的,无难度,飞过.

重点是那个接口的实现类了.PersonServiceBean

package com.liyu.service.impl;

import java.util.List;

import javax.annotation.Resource;

import org.hibernate.SessionFactory;

import org.springframework.transaction.annotation.Propagation;

import org.springframework.transaction.annotation.Transactional;

import com.liyu.bean.Person;

import com.liyu.service.PersonService;

@Transactional

public class PersonServiceBean implements PersonService {

    @Resource private SessionFactory sessionFactory;

    public void delete(Integer personid) {

       sessionFactory.getCurrentSession().delete(

              sessionFactory.getCurrentSession().load(Person.class, personid));

    }

    @Transactional(propagation=Propagation.NOT_SUPPORTED,readOnly=true)

    public Person getPerson(Integer personid) {

       return (Person)sessionFactory.getCurrentSession().get(Person.class, personid);

    }

    @Transactional(propagation=Propagation.NOT_SUPPORTED,readOnly=true)

    @SuppressWarnings("unchecked")

    public List<Person> getPersons() {

       return sessionFactory.getCurrentSession().createQuery("from Person").list();

    }

    public void save(Person person) {

       sessionFactory.getCurrentSession().persist(person);

    }

    public void update(Person person) {

       sessionFactory.getCurrentSession().merge(person);

    }

看看测试文件:

package com.liyu.test;

import java.util.List;

import org.springframework.context.ApplicationContext;

import org.springframework.context.support.ClassPathXmlApplicationContext;

import com.liyu.bean.Person;

import com.liyu.service.PersonService;

public class SshTest {

    public static void main(String[] args) {

       ApplicationContext applicationContext = new ClassPathXmlApplicationContext("beans.xml");

       PersonService ps = (PersonService)applicationContext.getBean("personService");

       //增加一条记录

       //ps.save(new Person("wang da"));

       //查找一条记录

       //Person p=ps.getPerson(7);

       //System.out.println(p.getName());

       //p.setName("FFFF3");

       //更新记录

       //ps.update(p);

       //p=ps.getPerson(2);

       //System.out.println(p.getName());

       //删除记录

       //ps.delete(6);

       List<Person> list=ps.getPersons();

       for(Person p:list){

           System.out.println(p.getName());

       }

    }
