Spring Social Facebook

Goal - use spring-social-quickstart for QAuth. We are adding login with Facebook. In the very begining we declare annotation datasource, entity manager, transactionManager

 @Bean
 public DataSource dataSource() throws SQLException {
    DriverManagerDataSource dataSource = new DriverManagerDataSource();

    dataSource.setDriverClassName(env.getProperty("db.driver"));
    dataSource.setUrl(env.getProperty("db.url"));
    dataSource.setUsername(env.getProperty("db.username"));
    dataSource.setPassword(env.getProperty("db.password"));

    return dataSource;
 }


 @Bean
 public EntityManagerFactory entityManagerFactory() throws SQLException {

    HibernateJpaVendorAdapter vendorAdapter = new HibernateJpaVendorAdapter();
    vendorAdapter.setGenerateDdl(true);

    LocalContainerEntityManagerFactoryBean factory = new LocalContainerEntityManagerFactoryBean();
    factory.setJpaVendorAdapter(vendorAdapter);
    factory.setPackagesToScan("com.streetup.model");
    factory.setDataSource(dataSource());
    factory.afterPropertiesSet();

    return factory.getObject();
 }

 @Bean
 public PlatformTransactionManager transactionManager() throws SQLException {

    JpaTransactionManager txManager = new JpaTransactionManager();
    txManager.setEntityManagerFactory(entityManagerFactory());
    return txManager;
 }
