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：

 

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

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

 9            http://www.springframework.org/schema/tx/spring-tx-2.0.xsd">

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"/>
19     </bean>
20     
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">

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 -->
36     <property name="hibernate.c3p0.max_size">10</property>
37     <!-- 最小连接数 -->
38     <property name="hibernate.c3p0.min_size">5</property>
39 
40     <!-- 自动建表 -->
41     <property name="hbm2ddl.auto">update</property>
42     
43     <property name="show_sql">true</property>
44     
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" />
50     
51 </session-factory>
53 </hibernate-configuration>

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