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

<?xml version='1.0' encoding='utf-8'?><br /> <!DOCTYPE hibernate-configuration PUBLIC<br /> "-//Hibernate/Hibernate Configuration DTD 3.0//EN"<br /> "http://hibernate.sourceforge.net/hibernate-configuration-3.0.dtd"></p> <p><hibernate-configuration></p> <p> <session-factory></p> <p> <!-- Database connection settings --><br /> <property name="connection.driver_class">com.mysql.jdbc.Driver</property><br /> <property name="connection.url">jdbc:mysql://localhost:3306/hibernate</property><br /> <property name="connection.username">root</property><br /> <property name="connection.password">***</property></p> <p> <!-- JDBC connection pool (use the built-in) --><br /> <property name="connection.pool_size">10</property></p> <p> <!-- SQL dialect --><br /> <property name="dialect">org.hibernate.dialect.MySQLDialect</property></p> <p> <!-- Enable Hibernate's automatic session context management --><br /> <property name="current_session_context_class">thread</property></p> <p> <!-- Disable the second-level cache --><br /> <property name="cache.provider_class">org.hibernate.cache.NoCacheProvider</property></p> <p> <!-- Echo all executed SQL to stdout --><br /> <property name="show_sql">true</property><br /> <property name="format_sql">true</property></p> <p> <!-- Drop and re-create the database schema on startup --><br /> <property name="hbm2ddl.auto">update</property></p> <p> <mapping resource="com/model/User.hbm.xml"/><br /> <!-- <mapping class="com.model.User"/>--></p> <p> </session-factory></p> <p></hibernate-configuration><br />

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：
