I am trying run a spring-boot application which uses hibernate via spring-jpa, but i am getting this error:

my pom.xml file is this:

my hibernate configuration is that (the dialect configuration is in the last method from this class):

@Configuration
@EnableTransactionManagement
@ComponentScan({ "com.spring.app" })
public class HibernateConfig {

   @Bean
   public LocalSessionFactoryBean sessionFactory() {
      LocalSessionFactoryBean sessionFactory = new LocalSessionFactoryBean();

      sessionFactory.setDataSource(restDataSource());
      sessionFactory.setPackagesToScan(new String[] { "com.spring.app.model" });
      sessionFactory.setHibernateProperties(hibernateProperties());

      return sessionFactory;
   }

   @Bean
   public DataSource restDataSource() {
      BasicDataSource dataSource = new BasicDataSource();

      dataSource.setDriverClassName("org.postgresql.Driver");
      dataSource.setUrl("jdbc:postgresql://localhost:5432/teste?charSet=LATIN1");
      dataSource.setUsername("klebermo");
      dataSource.setPassword("123");

      return dataSource;
   }

   @Bean
   @Autowired
   public HibernateTransactionManager transactionManager(SessionFactory sessionFactory) {
      HibernateTransactionManager txManager = new HibernateTransactionManager();
      txManager.setSessionFactory(sessionFactory);
      return txManager;
   }

   @Bean
   public PersistenceExceptionTranslationPostProcessor exceptionTranslation() {
      return new PersistenceExceptionTranslationPostProcessor();
   }

   Properties hibernateProperties() {
      return new Properties() {
         /**
         * 
         */
        private static final long serialVersionUID = 1L;

        {
            setProperty("hibernate.hbm2ddl.auto", "create");
            setProperty("hibernate.show_sql", "false");
            setProperty("hibernate.dialect", "org.hibernate.dialect.PostgreSQLDialect");
         }
      };
   }
}

what I am doing wrong here?
