Hibernate与Spring的整合

 

  Hibernate的核心是ORM，主要用于持久化管理，Spring核心为IOC，主要用于控制反转，依赖注入

 Hibernate与Spring的整合就是使用Spring来管理Hibernate，也就是管理持久化层

 Spring管理Hibernate有两种方式

 方式一：

  使用Hibernate连接数据库，Spring管理Hibernate

  1.hibernate.cfg.xml(Hibernate主要配置文件)

  <?xml version='1.0' encoding='UTF-8'?><!DOCTYPE hibernate-configuration PUBLIC "-//Hibernate/Hibernate Configuration DTD 3.0//EN" "http://hibernate.sourceforge.net/hibernate-configuration-3.0.dtd"><!-- Generated by MyEclipse Hibernate Tools. --><hibernate-configuration><session-factory><property name="connection.username">root</property><property name="connection.url">jdbc:mysql://localhost:3306/mysql</property><property name="dialect">org.hibernate.dialect.MySQLDialect</property><property name="myeclipse.connection.profile">mysql</property><property name="connection.password">123</property><property name="connection.driver_class">com.mysql.jdbc.Driver</property><property name="show_sql">true</property><property name="format_sql">true</property><property name="current_session_context_class">thread</property><mapping resource="com/feng/bean/Userinfo.hbm.xml" /></session-factory></hibernate-configuration>

 

2.applicationContext.xml(Spring主要配置文件)

<?xml version="1.0" encoding="UTF-8"?><beans xmlns="http://www.springframework.org/schema/beans"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"><bean id="sessionFactory"class="org.springframework.orm.hibernate3.LocalSessionFactoryBean"><property name="configLocation"value="classpath:hibernate.cfg.xml"></property></bean></beans>

 

 

方式二:

使用Spring连接数据库

1.applicationContext.xml(不需要hibernate.cfg.xml)

 <?xml version="1.0" encoding="UTF-8"?><beans xmlns="http://www.springframework.org/schema/beans"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"><bean id="sessionFactory"class="org.springframework.orm.hibernate3.LocalSessionFactoryBean"><property name="dataSource" ref="dataSource"></property><property name="hibernateProperties"><props><prop key="hibernate.dialect">org.hibernate.dialect.MySQLDialect</prop><prop key="show_sql">true</prop><prop key="format_sql">true</prop><prop key="current_session_context_class">thread</prop></props></property><property name="mappingResources"><list><value>com/feng/bean/Userinfo.hbm.xml</value></list></property></bean><bean id="dataSource"class="org.apache.commons.dbcp.BasicDataSource"><property name="driverClassName"value="com.mysql.jdbc.Driver"></property><property name="url"value="jdbc:mysql://localhost:3306/mysql"></property><property name="username" value="root"></property><property name="password" value="123"></property></bean></beans>
