Spring与Hibernate整合，实现Hibernate事务管理

1.所需的jar包

2.配置文件

<?xml version="1.0" encoding="utf-8" ?>
<!DOCTYPE hibernate-mapping PUBLIC
"-//Hibernate/Hibernate Mapping DTD 3.0//EN"
"http://www.hibernate.org/dtd/hibernate-mapping-3.0.dtd">
<hibernate-mapping package="com.juaner.entity">
<class name="Product">
<id name="id" column="id">
<generator class="native"/>
</id>
<property name="name" column="name"/>
<property name="price" column="price"/>
<property name="remark" column="remark"/>
</class>

</hibernate-mapping>

<!DOCTYPE hibernate-configuration PUBLIC
"-//Hibernate/Hibernate Configuration DTD 3.0//EN"
"http://www.hibernate.org/dtd/hibernate-configuration-3.0.dtd">

<hibernate-configuration>
<session-factory>
<!-- 数据库连接信息 -->
<property name="hibernate.dialect">org.hibernate.dialect.MySQLDialect</property>
<property name="hibernate.connection.driver_class">com.mysql.jdbc.Driver</property>
<property name="hibernate.connection.url">jdbc:mysql:///test</property>
<property name="hibernate.connection.username">root</property>
<property name="hibernate.connection.password">juaner767</property>
<property name="hibernate.show_sql">true</property>
<property name="hibernate.hbm2ddl.auto">update</property>
 <!--spring默认以线程方式创建，配了反而有问题-->
<!-- session创建方式 -->
<!--<property name="hibernate.current_session_context_class">thread</property>-->

<!-- 加载映射 -->
<mapping resource="com/juaner/entity/Product.hbm.xml"/>

</session-factory>
</hibernate-configuration>

3.直接加载hibernate文件的方式配置

<?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: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">
<!--dao-->
<bean id="productDao" class="com.juaner.dao.ProductDao">
<property name="sessionFactory" ref="sessionFactory"/>
</bean>
<!--service-->
<bean id="productService" class="com.juaner.service.ProductService">
<property name="productDao" ref="productDao"/>
</bean>

<!--spring与hibernate整合-->
<bean id="sessionFactory" class="org.springframework.orm.hibernate3.LocalSessionFactoryBean">
<!--通过配置文件创建sessionfactory对象-->
<property name="configLocation" value="hibernate.cfg.xml"></property>
</bean>
<!--事务配置-->
<!--配置事务管理器类-->
<bean id="txManager" class="org.springframework.orm.hibernate3.HibernateTransactionManager">
<property name="sessionFactory" ref="sessionFactory"/>
</bean>
<!--配置事务增强-->
<tx:advice id="txAdvice" transaction-manager="txManager">
<tx:attributes>
<tx:method name="*" read-only="false"/>
</tx:attributes>
</tx:advice>
<!--aop配置-->
<aop:config>
<aop:pointcut id="pt" expression="execution(* com.juaner.service.*.*(..))"/>
<aop:advisor advice-ref="txAdvice" pointcut-ref="pt"/>
</aop:config>
</beans>

4.spring配置连接池和hibernate常用配置

<?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: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">
<!--dao-->
<bean id="productDao" class="com.juaner.dao.ProductDao">
<property name="sessionFactory" ref="sessionFactory"/>
</bean>
<!--service-->
<bean id="productService" class="com.juaner.service.ProductService">
<property name="productDao" ref="productDao"/>
</bean>

<!--数据源配置-->
<bean id="dataSource" class="com.mchange.v2.c3p0.ComboPooledDataSource">
<property name="driverClass" value="com.mysql.jdbc.Driver"></property>
<property name="jdbcUrl" value="jdbc:mysql:///test"/>
<property name="user" value="root"/>
<property name="password" value="juaner767"/>
<property name="initialPoolSize" value="3"/>
<property name="maxPoolSize" value="6"/>
<property name="maxStatements" value="100"/>
<property name="acquireIncrement" value="2"/>
</bean>
<!--spring与hibernate整合-->
<!--方式2，使用spring创建连接池对象-->
<!--<bean id="sessionFactory" class="org.springframework.orm.hibernate3.LocalSessionFactoryBean">-->
<!--<!–通过配置文件创建sessionfactory对象–>-->
<!--<property name="configLocation" value="hibernate.cfg.xml"></property>-->
<!--<property name="dataSource" ref="dataSource"/>-->
<!--</bean>-->
<!--方式3，-->
<bean id="sessionFactory" class="org.springframework.orm.hibernate3.LocalSessionFactoryBean">
<property name="dataSource" ref="dataSource"/>
<!--hibernate常用配置-->
<property name="hibernateProperties">
<props>
<prop key="hibernate.dialect">org.hibernate.dialect.MySQLDialect</prop>
<prop key="hibernate.show_sql">true</prop>
<prop key="hibernate.hbm2ddl.auto">update</prop>
</props>
</property>
<!--映射文件配置-->
<property name="mappingDirectoryLocations">
<list>
<value>classpath:com/juaner/entity/</value>
</list>
</property>
</bean>
<!--事务配置-->
<!--配置事务管理器类-->
<bean id="txManager" class="org.springframework.orm.hibernate3.HibernateTransactionManager">
<property name="sessionFactory" ref="sessionFactory"/>
</bean>
<!--配置事务增强-->
<tx:advice id="txAdvice" transaction-manager="txManager">
<tx:attributes>
<tx:method name="*" read-only="false"/>
</tx:attributes>
</tx:advice>
<!--aop配置-->
<aop:config>
<aop:pointcut id="pt" expression="execution(* com.juaner.service.ProductService.*(..))"/>
<aop:advisor advice-ref="txAdvice" pointcut-ref="pt"/>
</aop:config>
</beans>
