How to use Spring Java configuration in place of XML Configuration for Easy-Cassandra?

[ScheideckerAntunes]

Otavio,

On your Easy-Cassandra example with Spring you create an XML file to load the beans as follows:

<bean id = "clusterInformation" class="org.easycassandra.persistence.cassandra.ClusterInformation">
	<property name="keySpace" value="campus" />
	<property name="hosts">
		<list>
			<value>localhost</value>
		</list>
	</property>
</bean>

<bean id="cassandraFactory" class="org.easycassandra.persistence.cassandra.spring.CassandraFactoryAnnotation">
	<constructor-arg name="clusterInformation" ref="clusterInformation" />
	<property name="annotatedClasses">
		<list>
			<value>org.easycassandra.persistence.cassandra.spring.entity.Contact</value>
            <value>org.easycassandra.bean.model.Step</value>
            <value>org.easycassandra.bean.model.Weight</value>
		</list>
	</property>
</bean>

<bean id="cassandraTemplate" class="org.easycassandra.persistence.cassandra.spring.SimpleCassandraTemplateImpl" >
	<constructor-arg name="factory" ref="cassandraFactory" />
</bean>

I would like to use Spring 4 and have those beans inside my RootContextConfiguration class.

From the book, Java Wev Aplications, you have the following example of the 3 beans while using MySQL:

@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()

        );

    }

So I imagine that I need a ClusterInformation bean that initializes org.easycassandra.persistence.cassandra.ClusterInformation object

A cassandraFactory bean that initiazlies a  org.easycassandra.persistence.cassandra.spring.CassandraFactoryAnnotation 

A cassandraTemplate bean that initializes a org.easycassandra.persistence.cassandra.spring.SimpleCassandraTemplateImpl 

Have you ever tried Easy-Cassandra with Spring 4?

Thank you,

Carlos.
