Spring与Hibernate整合(配置模式)

Spring与Hibernate整合的作用：

1、使用Spring的IOC容器管理SessionFactory对象

2、让Hibernate使用上Spring的声明式事务

Hibernate和Spring整合的时候的整合的关键点：SessionFactory

整合步骤：

(1)、添加jar包

Hibernate核心功能包

Spring的相关包

Spring和Hibernate整合的包

数据库驱动的相关包

c3p0连接池的相关包

(2)、在web.xml中配置Spring

<!--Spring的相关配置 -->
<context-param>
<param-name>contextConfigLocation</param-name>
<param-value>/WEB-INF/classes/config/bean-*.xml</param-value>
</context-param>

<listener>
<listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
</listener>

(3)、在我们的src/config下面添加配置文件

bean-base.xml

<beans xmlns="http://www.springframework.org/schema/beans"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:p="http://www.springframework.org/schema/p"

<!--将Hibernate中的连接数据库的相关信息配置到Spring中来 -->
<bean id="dataSource" class="com.mchange.v2.c3p0.ComboPooledDataSource">
<property name="acquireIncrement" value="2"></property>

<property name="minPoolSize" value="2"></property>
<property name="maxStatements" value="100"></property>
<property name="driverClass" value="com.mysql.jdbc.Driver"></property>
<property name="jdbcUrl" value="jdbc:mysql:///test01"></property>
<property name="user" value="root"></property>
<property name="password" value="123456"></property>
</bean>
<!--Spring和Hibernate整合的关键点是SessionFactory的创建问题 -->
<bean id="sessionFactory"
class="org.springframework.orm.hibernate5.LocalSessionFactoryBean">
<property name="dataSource" ref="dataSource"></property>
<property name="configLocations" value="classpath:config/hibernate.cfg.xml"></property>
</bean>
<!--配置事务 -->
<bean id="txManager"
class="org.springframework.orm.hibernate5.HibernateTransactionManager">
<property name="dataSource" ref="dataSource"></property>
<property name="sessionFactory" ref="sessionFactory"></property>
</bean>
<!--配置的是事物增强 -->
<tx:advice id="txAdvice" transaction-manager="txManager">
<tx:attributes>
<tx:method name="*" read-only="false" />
</tx:attributes>
</tx:advice>
<!--配置的是aop -->
<aop:config>
<aop:pointcut
expression="(execution (* com.wc.service.impl.*.*(..)))"
id="pt" />
<aop:advisor advice-ref="txAdvice" pointcut-ref="pt" />
</aop:config>
</beans>

hibernate.cfg.xml

<!DOCTYPE hibernate-configuration PUBLIC
"-//Hibernate/Hibernate Configuration DTD 3.0//EN"
"http://www.hibernate.org/dtd/hibernate-configuration-3.0.dtd">
<!--下面这个是用来配置hibernate的
-->
<hibernate-configuration>
<!--配置的是一个会话的工厂  name:一般不配置-->
<session-factory>
<!--配置数据库的方言-->
<property name="hibernate.dialect">org.hibernate.dialect.MySQL5Dialect</property>
<!--自动建表-->
<property name="hibernate.hbm2ddl.auto">update</property>
<!--展示sql-->
<property name="hibernate.show_sql">true</property>
<!--格式化sql-->
<property name="hibernate.format_sql">true</property>
<!--配置映射-->
<mapping resource="com/wc/pojo/User.hbm.xml"/>
</session-factory>
</hibernate-configuration>

第二种模式：

将Hibernate.cfg.xml放入bean-base.xml中

<?xml version="1.0" encoding="UTF-8"?>
