How to configure Spring Data JPA using XML

Question

I'm reading the book "Professional Java for Web Applications - Nicholas S. Williams" The book example has this configuration for 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()     ); } 

But I have been configuring using XML, I cannot figure out how to translate this to XML only, I have this so far

<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> 

Can any one guide me how to convert this?

Thanks

If you want to configure Spring Data JPA by using XML configuration (and use the configuration described in the book), you have to follow these steps:

1. Configure the data source bean.
2. Configure the entity manager factory bean.
3. Configure the transaction manager bean.
4. Enable annotation driven transaction management.
5. Configure Spring Spring Data JPA.

The application context configuration (applicationContext-persistence.xml) file looks as follows:

<?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:jpa="http://www.springframework.org/schema/data/jpa"   xmlns:tx="http://www.springframework.org/schema/tx"   xmlns:context="http://www.springframework.org/schema/context"   xsi:schemaLocation="http://www.springframework.org/schema/beans      http://www.springframework.org/schema/beans/spring-beans.xsd     http://www.springframework.org/schema/data/jpa      http://www.springframework.org/schema/data/jpa/spring-jpa-1.0.xsd     http://www.springframework.org/schema/tx      http://www.springframework.org/schema/tx/spring-tx-3.1.xsd     http://www.springframework.org/schema/context      http://www.springframework.org/schema/context/spring-context-3.1.xsd">    <!-- Configure the data source bean -->   <jee:jndi-lookup id="dataSource" jndi-name="java:comp/env/jdbc/CustomerSupport"/>    <!-- Create default configuration for Hibernate -->   <bean id="hibernateJpaVendorAdapter"      class="org.springframework.orm.jpa.vendor.HibernateJpaVendorAdapter"/>    <!-- Configure the entity manager factory bean -->   <bean id="entityManagerFactory"      class="org.springframework.orm.jpa.LocalContainerEntityManagerFactoryBean">     <property name="dataSource" ref="dataSource"/>     <property name="jpaVendorAdapter" ref="hibernateJpaVendorAdapter"/>     <!-- Set JPA properties -->     <property name="jpaProperties">       <props>         <prop key="hibernate.dialect">org.hibernate.dialect.MySQL5InnoDBDialect</prop>         <prop key="javax.persistence.schema-generation.database.action">none</prop>         <prop key="hibernate.ejb.use_class_enhancer">true</prop>       </props>     </property>     <!-- Set base package of your entities -->     <property name="packagesToScan" value="foo.bar.model"/>     <!-- Set share cache mode -->     <property name="sharedCacheMode" value="ENABLE_SELECTIVE"/>     <!-- Set validation mode -->     <property name="validationMode" value="NONE"/>   </bean>    <!-- Configure the transaction manager bean -->   <bean id="transactionManager"      class="org.springframework.orm.jpa.JpaTransactionManager">     <property name="entityManagerFactory" ref="entityManagerFactory"/>   </bean>    <!-- Enable annotation driven transaction management -->   <tx:annotation-driven/>    <!--      Configure Spring Data JPA and set the base package of the      repository interfaces    -->   <jpa:repositories base-package="foo.bar.repository"/> </beans>
