spring_hibernate_annotation的三种实现

xml 代码

<!--第一种 ==================hibernate cfg配置文件＋AnnotationConfiguration==================== -->
    <bean id="sessionFactory"
        class="org.springframework.orm.hibernate3.LocalSessionFactoryBean">
        <property name="configurationClass">
            <value>org.hibernate.cfg.AnnotationConfiguration</value>
        </property>
        <property name="dataSource">
            <ref bean="dataSource" />
        </property>
        <property name="configLocation">
            <value>/hibernate.cfg.xml</value>
        </property>
    </bean>

<!-- 第二种============直接使用AnnotationSessionFactoryBean================================ -->
    <bean id="annSessionFactory"
        class="org.springframework.orm.hibernate3.annotation.AnnotationSessionFactoryBean">
        <property name="dataSource" ref="dataSource" />
        <property name="annotatedClasses">
            <list>
                <value>test.model.User</value>
            </list>
        </property>
    </bean>

    <!--第三种 ==============EntityManagerFactoryBean 使用用hibernate 的 jpa 实现================= -->
    <bean id="entityManagerFactory"
        class="org.springframework.orm.jpa.LocalContainerEntityManagerFactoryBean">
        <property name="dataSource" ref="dataSource" />
        <property name="jpaVendorAdapter">
            <bean
                class="org.springframework.orm.jpa.vendor.HibernateJpaVendorAdapter">
                <property name="database" value="MYSQL" />
                <property name="showSql" value="true" />
            </bean>
        </property>
    </bean>

    </bean>
