Spring与Hibernate整合(配置模式)

来源：互联网发布：河南安全教育网络平台编辑：程序博客网时间：2024/06/05 08:43

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"    xmlns:context="http://www.springframework.org/schema/context" xmlns:tx="http://www.springframework.org/schema/tx"    xmlns:aop="http://www.springframework.org/schema/aop"    xsi:schemaLocation="        http://www.springframework.org/schema/beans        http://www.springframework.org/schema/beans/spring-beans.xsd        http://www.springframework.org/schema/context        http://www.springframework.org/schema/context/spring-context.xsd        http://www.springframework.org/schema/tx        http://www.springframework.org/schema/tx/spring-tx.xsd        http://www.springframework.org/schema/aop        http://www.springframework.org/schema/aop/spring-aop.xsd">    <!--配置dao -->    <bean id="userDao" class="com.wc.dao.impl.UserDao" p:sessionFactory-ref="sessionFactory"></bean>    <!--配置Service -->    <bean id="userService" class="com.wc.service.impl.UserService" p:userDao-ref="userDao"></bean>    <!--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="maxPoolSize" value="100"></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"?><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"    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        http://www.springframework.org/schema/beans/spring-beans.xsd        http://www.springframework.org/schema/context        http://www.springframework.org/schema/context/spring-context.xsd        http://www.springframework.org/schema/aop        http://www.springframework.org/schema/aop/spring-aop.xsd        http://www.springframework.org/schema/tx        http://www.springframework.org/schema/tx/spring-tx.xsd">        <!-- 配置dao -->        <bean id="userDao"   class="com.wc.dao.impl.UserDao" p:sessionFactory-ref="sessionFactory">        </bean>        <!-- 配置Service -->        <bean id="userService"  class="com.wc.service.impl.UserService" p:userDao-ref="userDao">        </bean>         <!-- 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="maxPoolSize" value="100"></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>                <!--下面我要将hibernate的配置文件写到这个里面来-->                <property name="hibernateProperties">                    <props>                        <prop key="hibernate.dialect">org.hibernate.dialect.MySQL5Dialect</prop>                        <prop key="hibernaye.hbm2ddl.auto" >update</prop>                        <prop key="hibernate.show_sql">true</prop>                        <prop key="hibernate.format_sql">true</prop>                    </props>                </property>                <!-- 编写hibernate的映射配置 -->                <property name="mappingDirectoryLocations">                    <list>                        <!-- 配置mapping映射文件的根路径就好了 -->                        <value>classpath:com/wc/pojo</value>                    </list>                </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>        <tx:advice id="txAdvice" transaction-manager="txManager">            <tx:attributes>                <tx:method name="*" read-only="false"/>            </tx:attributes>        </tx:advice>        <!-- 配置AOp -->        <aop:config>            <aop:pointcut expression="(execution (* com.wc.service.impl.*.*(..)))" id="pt"/>            <aop:advisor advice-ref="txAdvice" pointcut-ref="pt"/>        </aop:config></beans>
