如何使用XML配置Spring数据JPA

我在读这本书“专业 Java for Web Applications – Nicholas S. Williams”
本书的示例对于Spring Data JPA具有此配置：

@Bean
public DataSource customerSupportDataSource()
{
    JndiDataSourceLookup lookup = new JndiDataSourceLookup();
    return lookup.getDataSource("jdbc/CustomerSupport");
}

@Bean
public LocalContainerEntityManagerfactorybean entityManagerfactorybean()
{
    Map<String,Object> properties = new Hashtable<>();
    properties.put("javax.persistence.schema-generation.database.action","none");
    properties.put("hibernate.ejb.use_class_enhancer","true");

    HibernateJpaVendorAdapter adapter = new HibernateJpaVendorAdapter();
    adapter.setDatabasePlatform("org.hibernate.dialect.MysqL5InnoDBDialect");

    LocalContainerEntityManagerfactorybean factory =
            new LocalContainerEntityManagerfactorybean();
    factory.setJpaVendorAdapter(adapter);
    factory.setDataSource(this.customerSupportDataSource());
    factory.setPackagesToScan("com.wrox.site.entities","com.wrox.site.converters");
    factory.setSharedCacheMode(SharedCacheMode.ENABLE_SELECTIVE);
    factory.setValidationMode(ValidationMode.NONE);
    factory.setLoadTimeWeaver(this.loadTimeWeaver); // TODO: remove when SPR-10856 fixed
    factory.setJpaPropertyMap(properties);
    return factory;
}

@Bean
public PlatformTransactionManager jpaTransactionManager()
{
    return new JpaTransactionManager(
            this.entityManagerfactorybean().getObject()
    );
}

但是我一直在使用XML进行配置,我不知道如何将它翻译成只有XML,我到目前为止

<jee:jndi-lookup id="myDataSource" jndi-name="java:comp/env/jdbc/test"/>

<bean id="transactionManager" class="org.springframework.orm.jpa.JpaTransactionManager">
    <property name="entityManagerFactory" ref="myEmf" />
</bean>

<bean id="myEmf" class="org.springframework.orm.jpa.LocalContainerEntityManagerfactorybean">
    <property name="dataSource" ref="myDataSource" />
    <property name="packagesToScan" value="com.test" />
</bean>

任何人可以指导我如何转换？

谢谢

如果要使用XML配置来配置Spring Data JPA(并使用本书中描述的配置),则必须按照以下步骤操作：

>配置数据源bean.
>配置实体管理器工厂bean.
>配置事务管理器bean.
启用注释驱动的事务管理.
>配置Spring Spring数据JPA.

应用程序上下文配置(applicationContext-persistence.xml)文件如下所示：
