First remove all of your configuration Spring Boot will start it for you.

Make sure you have an application.properties in your classpath and add the following properties.

spring.datasource.url=jdbc:postgresql://localhost:5432/teste?charSet=LATIN1
spring.datasource.username=klebermo
spring.datasource.password=123

spring.jpa.database-platform=org.hibernate.dialect.PostgreSQLDialect
spring.jpa.show-sql=false
spring.jpa.hibernate.ddl-auto=create

If you really need access to a SessionFactory and that is basically for the same datasource, then you can do the following (which is also documented here although for XML, not JavaConfig).

@Configuration        
public class HibernateConfig {

    @Bean
    public HibernateJpaSessionFactoryBean sessionFactory(EntityManagerFactory emf) {
         HibernateJpaSessionFactoryBean factory = new HibernateJpaSessionFactoryBean();
         factory.setEntityManagerFactory(emf);
         return factory;
    }
}

That way you have both an EntityManagerFactory and a SessionFactory.

UPDATE: As of Hibernate 5 the SessionFactory actually extends the EntityManagerFactory. So to obtain a SessionFactory you can simply cast the EntityManagerFactory to it or use the unwrap method to get one.

public class SomeHibernateRepository {

  @PersistenceUnit
  private EntityManagerFactory emf;

  protected SessionFactory getSessionFactory() {
    return emf.unwrap(SessionFactory.class);
  }

}

Assuming you have a class with a main method with @EnableAutoConfiguration you don’t need the @EnableTransactionManagement annotation, as that will be enabled by Spring Boot for you. A basic application class in the com.spring.app package should be enough.

@Configuration
@EnableAutoConfiguration
@ComponentScan
public class Application {


    public static void main(String[] args) throws Exception {
        SpringApplication.run(Application.class, args);
    }

} 

Something like that should be enough to have all your classes (including entities and Spring Data based repositories) detected.

UPDATE: These annotations can be replaced with a single @SpringBootApplication in more recent versions of Spring Boot.

@SpringBootApplication
public class Application {

    public static void main(String[] args) throws Exception {
        SpringApplication.run(Application.class, args);
    }
} 

I would also suggest removing the commons-dbcp dependency as that would allow Spring Boot to configure the faster and more robust HikariCP implementation.
