So konfigurieren Sie Spring Data JPA mit XML

Ich lese das Buch "Professional Java für Webanwendungen - Nicholas S. Williams". Das Buchbeispiel enthält die folgende Konfiguration für Spring Data JPA:

@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()
    );
}

Aber ich habe mit XML konfiguriert. Ich kann nicht herausfinden, wie dies nur in XML übersetzt werden soll. Ich habe dies bisher

<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>

Kann mir jemand helfen, wie man das umsetzt?

Vielen Dank

Wenn Sie Spring Data JPA mithilfe der XML-Konfiguration konfigurieren möchten (und die im Handbuch beschriebene Konfiguration verwenden möchten), müssen Sie die folgenden Schritte ausführen:

  1. Konfigurieren Sie die Datenquellen-Bean.
  2. Konfigurieren Sie das Entity Manager Factory Bean.
  3. Konfigurieren Sie die Transaktionsmanager-Bean.
  4. Aktivieren Sie das annotationsgesteuerte Transaktionsmanagement.
  5. Konfigurieren Sie Spring Spring Data JPA.

Die Anwendungskontext-Konfigurationsdatei (applicationContext-persistence.xml) sieht folgendermaßen aus:
