spring2.5整合hibernate3.0

第一步：配置文件

代码部分：

1.person.java

package cn.itcast.bean;

public class Person {
    private Integer id;
    private String name;
    
    public Person() {}

    public Person(String name) {
        this.name = name;
    }
    
    public Integer getId() {
        return id;
    }
    public void setId(Integer id) {
        this.id = id;
    }
    public String getName() {
        return name;
    }
    public void setName(String name) {
        this.name = name;
    }
    
    
    
}

2.Person.hbm.xml

<?xml version="1.0"?>
<!DOCTYPE hibernate-mapping PUBLIC "-//Hibernate/Hibernate Mapping DTD 3.0//EN"

<!-- Generated 2016-6-1 10:08:44 by Hibernate Tools 3.4.0.CR1 -->

        </id>
        <property name="name"/>
    </class>
</hibernate-mapping>

3.PersonService 接口

package cn.itcast.Service;

import java.util.List;

import cn.itcast.bean.Person;

public interface PersonService {

    public abstract void save(Person person);

    public abstract void update(Person person);

    public abstract Person getPerson(Integer personId);

    public abstract void delete(Integer personId);

    public abstract List<Person> getPersons();

}

4.PersonService接口的实现类PersonServiceBean 

package cn.itcast.Service.Impl;

import java.util.List;

import javax.annotation.Resource;

import org.hibernate.Session;
import org.hibernate.SessionFactory;
import org.springframework.transaction.annotation.Propagation;
import org.springframework.transaction.annotation.Transactional;

import cn.itcast.Service.PersonService;
import cn.itcast.bean.Person;
@Transactional
public class PersonServiceBean implements PersonService {
    @Resource
    private SessionFactory sessionFactory;
    
    @Override
    public void save(Person person){
        //取被spring容器管理的session
        sessionFactory.getCurrentSession().persist(person);
    }
    
    @Override
    public void update(Person person){
        sessionFactory.getCurrentSession().merge(person);
    }
    
    @Transactional(propagation = Propagation.NOT_SUPPORTED,readOnly = true)
    @Override
    public Person getPerson(Integer personId){
        return (Person) sessionFactory.getCurrentSession().get(Person.class, personId);
        
    }
    
    @Override
    public void delete(Integer personId){
        sessionFactory.getCurrentSession().delete(sessionFactory.getCurrentSession().load(Person.class, personId));
    }
    
    @Transactional(propagation =Propagation.NOT_SUPPORTED,readOnly = true)
    @SuppressWarnings("unchecked")
    @Override
    public List<Person> getPersons(){
        return sessionFactory.getCurrentSession().createQuery("from person").list();
        
    }
}

5.测试类

package cn.itcast.Service.Impl;

import static org.junit.Assert.*;

import java.util.List;

import org.junit.BeforeClass;
import org.junit.Test;
import org.springframework.context.ApplicationContext;
import org.springframework.context.support.ClassPathXmlApplicationContext;

import cn.itcast.Service.PersonService;
import cn.itcast.bean.Person;

public class PersonServiceBeanTest {
    private static PersonService ps;
    @BeforeClass
    public static void setUpBeforeClass() throws Exception {
        try {
            ApplicationContext ctx = new ClassPathXmlApplicationContext("beans.xml");
            ps = (PersonService) ctx.getBean("personService");
        } catch (Exception e) {
            e.printStackTrace();
        }
    }

    @Test
    public void testSave() {
        ps.save(new Person("小明3"));
    }

    @Test
    public void testUpdate() {
        Person person = ps.getPerson(1);
        person.setName("小明修改版");
        ps.update(person);
    }

    @Test
    public void testGetPerson() {
        Person p = ps.getPerson(1);
        System.out.println(p.getName());
    }

    @Test
    public void testDelete() {
        ps.delete(2);
    }

    @Test
    public void testGetPersons() {
        List<Person> list = ps.getPersons();
        for (Person person : list) {
            person.getName();
        }
    }

}
