@Bean
public LocalContainerEntityManagerFactoryBean entityManagerFactory() {
LocalContainerEntityManagerFactoryBean em = new LocalContainerEntityManagerFactoryBean();
em.setDataSource(dataSource());
em.setPackagesToScan(new String[] { "com.XY.model" });
JpaVendorAdapter vendorAdapter = new HibernateJpaVendorAdapter();
em.setJpaVendorAdapter(vendorAdapter);
em.setJpaProperties(additionalProperties());
return em;
}
Properties additionalProperties() {
Properties properties = new Properties();
properties.setProperty("hibernate.hbm2ddl.auto", "update");
properties.setProperty("hibernate.dialect", "org.hibernate.dialect.PostgreSQL9Dialect");
properties.setProperty("hibernate.show_sql", "true");
return properties;
}
Източник на данни (редактиране на потребителско име, парола и адрес на хост):

dataSource.setUsername("root");
dataSource.setPassword("");
return dataSource;
}
Мениджър на транзакции:
@Bean
public PlatformTransactionManager transactionManager(EntityManagerFactory emf) {
JpaTransactionManager transactionManager = new JpaTransactionManager();
transactionManager.setEntityManagerFactory(emf);
return transactionManager;
}
