Spring与Hibernate整合，实现Hibernate事务管理

Posted 2020-07-26 十三弦

1.所需的jar包

连接池/数据库驱动包

Hibernate相关jar

Spring 核心包(5个)

Spring aop 包(4个)

spring-orm-3.2.5.RELEASE.jar                 【spring对hibernate的支持】

spring-tx-3.2.5.RELEASE.jar                     【事务相关】

2.配置文件

Product.hbm.xml

<?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>

hibernate.cfg.xml

<!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

bean.xml

<?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">-->
        <!--&lt;!&ndash;通过配置文件创建sessionfactory对象&ndash;&gt;-->
        <!--<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>
