知识点： 1、在框架集成中spring这个框架充当的角色是黏合的作用，所以在做集成的时候我们需要将hibennate的配置文件交给spring启动。
2、目标
3、通知
4、代理
5、sessionFactory的注入
首先看一下目录结构：
步骤一：反转出相对应的实体，啰嗦一句，实体必须要有主键（代码如下）：
package cn.zhuojingxinxi.entity;
/**
* Person entity.
*
* @author MyEclipse Persistence Tools
*/
public class Person implements java.io.Serializable {
// Fields
private Long pid;
private String pname;
private String pass;
// Constructors
/** default constructor */
public Person() {
}
/** full constructor */
public Person(String pname, String pass) {
this.pname = pname;
this.pass = pass;
}
// Property accessors
public Long getPid() {
return this.pid;
}
public void setPid(Long pid) {
this.pid = pid;
}
public String getPname() {
return this.pname;
}
public void setPname(String pname) {
this.pname = pname;
}
public String getPass() {
return this.pass;
}
public void setPass(String pass) {
this.pass = pass;
}
}
<?xml version="1.0" encoding="utf-8"?>
<!DOCTYPE hibernate-mapping PUBLIC "-//Hibernate/Hibernate Mapping DTD 3.0//EN"
"http://hibernate.sourceforge.net/hibernate-mapping-3.0.dtd">
<!--
Mapping file autogenerated by MyEclipse Persistence Tools
-->
<hibernate-mapping>
<class name="cn.zhuojingxinxi.entity.Person" table="PERSON" schema="SCOTT">
<id name="pid" type="java.lang.Long">
<column name="PID" precision="22" scale="0" />
<generator class="increment" />
</id>
<property name="pname" type="java.lang.String">
<column name="PNAME" length="50" />
</property>
<property name="pass" type="java.lang.String">
<column name="PASS" length="50" />
</property>
</class>
</hibernate-mapping>
步骤二、编写Dao层，请一定要编写接口（代码如下）：
PersonDao接口：
package cn.zhuojingxinxi.dao;
import cn.zhuojingxinxi.entity.Person;
public interface PersonDao {
public void savePerson(Person person);
}
PersonDaoImp实现类（为了能够拿到session必须继承HibernateDaoSupport）：
package cn.zhuojingxinxi.dao.impl;
import org.springframework.orm.hibernate3.support.HibernateDaoSupport;
import cn.zhuojingxinxi.dao.PersonDao;
import cn.zhuojingxinxi.entity.Person;
public class PersonDaoImpl extends HibernateDaoSupport implements PersonDao {
public void savePerson(Person person) {
this.getHibernateTemplate().save(person);
}
}
步骤三、编写biz层（即业务处理层）（同样必须写接口）：
PersonService接口：
package cn.zhuojingxinxi.biz;
import cn.zhuojingxinxi.entity.Person;
public interface PersonService {
public void savePerson(Person person);
}
PersonServiceImp实现类（实现类中操作dao层中的方法，所以必须将PersonDao注入进来）：
package cn.zhuojingxinxi.biz.impl;
import cn.zhuojingxinxi.biz.PersonService;
import cn.zhuojingxinxi.dao.PersonDao;
import cn.zhuojingxinxi.entity.Person;
public class PersonServiceImpl implements PersonService{
private PersonDao personDao=null;
public void setPersonDao(PersonDao personDao) {
this.personDao = personDao;
}
public void savePerson(Person person) {
personDao.savePerson(person);
}
}
步骤四、编写测试类代码（假如还要和struts2集成，不要开tomcat测试，因为加载速度慢，所以编写测试类是有必要的）
package cn.zhuojingxinxi.test;
import org.hibernate.Session;
import org.hibernate.SessionFactory;
import org.springframework.context.ApplicationContext;
import org.springframework.context.support.ClassPathXmlApplicationContext;
import cn.zhuojingxinxi.biz.PersonService;
import cn.zhuojingxinxi.dao.PersonDao;
import cn.zhuojingxinxi.entity.Person;
public class Test {
public static void main(String[] args) {
ApplicationContext context=new ClassPathXmlApplicationContext(new String[]{"applicationContext.xml"});
// SessionFactory sessionFactory= (SessionFactory)context.getBean("sessionFactory");
// Session session=sessionFactory.openSession();
//
// System.out.println(session);
PersonDao dao=(PersonDao)context.getBean("personDao");
PersonService personService=(PersonService)context.getBean("personService");
Person p=new Person();
p.setPname("xiaohua");
p.setPass("123321");
personService.savePerson(p);
}
}
步骤五、applicationContext.xml的编写（非常重要）
<?xml version="1.0" encoding="UTF-8"?> <beans xmlns="http://www.springframework.org/schema/beans" xmlns:tx="http://www.springframework.org/schema/tx" xmlns:aop="http://www.springframework.org/schema/aop" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-2.0.xsd http://www.springframework.org/schema/tx http://www.springframework.org/schema/tx/spring-tx-2.0.xsd http://www.springframework.org/schema/aop http://www.springframework.org/schema/aop /spring-aop-2.0.xsd" > <bean id="sessionFactory" class="org.springframework.orm.hibernate3.LocalSessionFactoryBean"> <property name="configLocation" value="classpath:hibernate.cfg.xml"> </property> </bean> <bean id="personDao" class="cn.zhuojingxinxi.dao.impl.PersonDaoImpl"> <property name="sessionFactory" ref="sessionFactory"></property> </bean> <!-- 目标 --> <bean id="personService" class="cn.zhuojingxinxi.biz.impl.PersonServiceImpl"> <property name="personDao" ref="personDao"></property> </bean> <!-- 定义一个事务管理器(通知) --> <bean id="transactionManage" class="org.springframework.orm.hibernate3.HibernateTransactionManager"> <property name="sessionFactory" ref="sessionFactory"></property> </bean> <!-- 代理 --> <bean id="personServiceProxy" class="org.springframework.transaction.interceptor.TransactionProxyFactoryBean"> <property name="target" ref="personService"></property> <property name="transactionManager" ref="transactionManage"></property> <property name="transactionAttributes"> <props> <prop key="save*">PROPAGATION_REQUIRED</prop> </props> </property> </bean> </beans>
需要注意的是：必须配置开头的tx、aop，否则事务是不会提交的。
