@Configuration
public class JpaConfiguration {

	@Value("#{dataSource}")
	private javax.sql.DataSource dataSource;

	@Bean
	public Map<String, Object> jpaProperties() {
		Map<String, Object> props = new HashMap<String, Object>();
		props.put("hibernate.dialect", "");
		props.put("hibernate.cache.provider_class", "");
		return props;
	}

	@Bean
	public JpaVendorAdapter jpaVendorAdapter() {
		HibernateJpaVendorAdapter hibernateJpaVendorAdapter = new HibernateJpaVendorAdapter();
		hibernateJpaVendorAdapter.setShowSql(false);
		hibernateJpaVendorAdapter.setGenerateDdl(false);
		hibernateJpaVendorAdapter.setDatabase(Database.ORACLE);
		return hibernateJpaVendorAdapter;
	}

	@Bean
	public PlatformTransactionManager transactionManager() {
		//JpaTransactionManager jpaTransactionManager=new JpaTransactionManager();
             //jpaTransactionManager.setEntityManagerFactory(localContainerEntityManagerFactoryBean().getObject());
		return new JpaTransactionManager( localContainerEntityManagerFactoryBean().getObject() );
	}

	@Bean
	public LocalContainerEntityManagerFactoryBean localContainerEntityManagerFactoryBean() {
		LocalContainerEntityManagerFactoryBean lef = new LocalContainerEntityManagerFactoryBean();
		lef.setDataSource(this.dataSource);
		lef.setJpaPropertyMap(this.jpaProperties());
		lef.setJpaVendorAdapter(this.jpaVendorAdapter());
		lef.setPersistenceUnitName("");
		lef.setPackagesToScan("");
		return lef;
	}
