本文主要记录spring整合hibernate的时候，直接使用hibernate.cfg.xml文件注入SessionFactory，applicationContext.xml文件配置如下：

<?xml  version="1.0"  encoding="UTF-8"?>
<beans  xmlns="http://www.springframework.org/schema/beans"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xmlns:aop="http://www.springframework.org/schema/aop"
xsi:schemaLocation="
http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-3.0.xsd
http://www.springframework.org/schema/aop http://www.springframework.org/schema/aop/spring-aop-3.0.xsd">

<bean  id="sessionFactory"  class="org.springframework.orm.hibernate3.LocalSessionFactoryBean">
<property  name="configLocations">
<value>classpath:hibernate.cfg.xml</value>
</property>
</bean>

<bean  id="userDao"  class="com.dao.impl.UserDaoImpl"  >
<property  name="sessionFactory"  ref="sessionFactory"></property>
</bean>

<bean  id="userService"  class="com.service.UserService"  >
<property  name="userDao"  ref="userDao"></property>
</bean>

</beans>

<?xml version="1.0" encoding="UTF-8"?> <beans xmlns="http://www.springframework.org/schema/beans" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:aop="http://www.springframework.org/schema/aop" xsi:schemaLocation=" http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-3.0.xsd http://www.springframework.org/schema/aop http://www.springframework.org/schema/aop/spring-aop-3.0.xsd"> <bean id="sessionFactory" class="org.springframework.orm.hibernate3.LocalSessionFactoryBean"> <property name="configLocations"> <value>classpath:hibernate.cfg.xml</value> </property> </bean> <bean id="userDao" class="com.dao.impl.UserDaoImpl" > <property name="sessionFactory" ref="sessionFactory"></property> </bean> <bean id="userService" class="com.service.UserService" > <property name="userDao" ref="userDao"></property> </bean> </beans>
hibernate.cfg.xml配置文件如下：

<?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">

<hibernate-configuration>

<session-factory>

<!-- Database connection settings -->
<property  name="connection.driver_class">com.mysql.jdbc.Driver</property>
<property  name="connection.url">jdbc:mysql://localhost:3306/hibernate</property>
<property  name="connection.username">root</property>
<property  name="connection.password">***</property>

<!-- JDBC connection pool (use the built-in) -->
<property  name="connection.pool_size">10</property>

<!-- SQL dialect -->
<property  name="dialect">org.hibernate.dialect.MySQLDialect</property>

<!-- Enable Hibernate's automatic session context management -->
<property  name="current_session_context_class">thread</property>

<!-- Disable the second-level cache -->
<property  name="cache.provider_class">org.hibernate.cache.NoCacheProvider</property>

<!-- Echo all executed SQL to stdout -->
<property  name="show_sql">true</property>
<property  name="format_sql">true</property>

<!-- Drop and re-create the database schema on startup -->
<property  name="hbm2ddl.auto">update</property>

<mapping  resource="com/model/User.hbm.xml"/>
<!-- <mapping class="com.model.User"/>-->

</session-factory>

</hibernate-configuration>

<?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"> <hibernate-configuration> <session-factory> <!-- Database connection settings --> <property name="connection.driver_class">com.mysql.jdbc.Driver</property> <property name="connection.url">jdbc:mysql://localhost:3306/hibernate</property> <property name="connection.username">root</property> <property name="connection.password">***</property> <!-- JDBC connection pool (use the built-in) --> <property name="connection.pool_size">10</property> <!-- SQL dialect --> <property name="dialect">org.hibernate.dialect.MySQLDialect</property> <!-- Enable Hibernate's automatic session context management --> <property name="current_session_context_class">thread</property> <!-- Disable the second-level cache --> <property name="cache.provider_class">org.hibernate.cache.NoCacheProvider</property> <!-- Echo all executed SQL to stdout --> <property name="show_sql">true</property> <property name="format_sql">true</property> <!-- Drop and re-create the database schema on startup --> <property name="hbm2ddl.auto">update</property> <mapping resource="com/model/User.hbm.xml"/> <!-- <mapping class="com.model.User"/>--> </session-factory> </hibernate-configuration>

由于hibernate.cfg.xml文件和applicationContext文件独立开来了，这样更便于hibernate自己独立配置管理，而spring所起的作用只是注入SessionFactory，这样思路更明确，而不是在applicationContext.xml中既要配置Datasource,又要配置SessionFactory,很麻烦，分工明确思路清晰

配置的核心就是：

<bean  id="sessionFactory"  class="org.springframework.orm.hibernate3.LocalSessionFactoryBean">
<property  name="configLocations">
<value>classpath:hibernate.cfg.xml</value>
</property>
</bean>
