Spring结合Hibernate的配置方法之一：直接引用hibernate文件

Spring结合Hibernate主要有集中配置方式，分别是

1、直接引用hibernate的*.cfg.xml配置文件

2、

3、

一、直接饮用hibernate的*.cfg.xml配置文件

项目的包结构如下：

 

此时Spring配置文件applicationContext.xml配置如下：

1 <?xml version="1.0" encoding="UTF-8"?>
2 <beans xmlns="http://www.springframework.org/schema/beans" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:context="http://www.springframework.org/schema/context" xmlns:aop="http://www.springframework.org/schema/aop" xmlns:tx="http://www.springframework.org/schema/tx" xsi:schemaLocation="http://www.springframework.org/schema/beans

11 <!-- Spring整合Hibernate：直接饮用hibernate配置文件-->
12 <bean id="sessionFactory" class="org.springframework.orm.hibernate3.annotation.AnnotationSessionFactoryBean">
13 <property name="configLocation" value="classpath:chanjiayi.cfg.xml"></property>
14 </bean>
15
16 <!-- 使用HibernateTemplate必须将sessionFactory注入DAO类中 -->
17 <bean id="userDAO" class="com.chanjiayi.dao.impl.UserDAOImpl">
18 <property name="sessionFactory" ref="sessionFactory"/>

21 <bean id="userService" class="com.chanjiayi.service.impl.UserServiceImpl">
22 <property name="dao" ref="userDAO"/>
23 </bean>
24
25 </beans>

hibenate的配置文件chanjiayi.cfg.xml配置：

1 <?xml version='1.0' encoding='UTF-8'?>
2 <!DOCTYPE hibernate-configuration PUBLIC
3 "-//Hibernate/Hibernate Configuration DTD 3.0//EN"
4 "http://hibernate.sourceforge.net/hibernate-configuration-3.0.dtd">

22 <property name="dialect">

26 <!-- 配置C3P0连接池及连接池属性 -->
27 <property name="hibernate.connection.provider_class">

30 <property name="hibernate.c3p0.timeout">120</property>
31 <!--连接池中保留的最小连接数。-->
32 <property name="minPoolSize">5</property>
33 <!--连接池中保留的最大连接数。Default: 15 -->
34 <property name="maxPoolSize">15</property>
35 <!-- 最大连接数 -->

37 <!-- 最小连接数 -->
38 <property name="hibernate.c3p0.min_size">5</property>

40 <!-- 自动建表 -->
41 <property name="hbm2ddl.auto">update</property>

43 <property name="show_sql">true</property>

45 <property name="connection.autocommit">true</property>
46 <mapping class="com.chanjiayi.pojo.Order" />
47 <mapping class="com.chanjiayi.pojo.Product" />
48 <mapping class="com.chanjiayi.pojo.User" />
49 <mapping class="com.chanjiayi.pojo.UserInfo" />

使用了C3P0连接池，我使用的Jar包是：c3p0-0.9.0.2.jar。点击下载。
