org.hibernate.HibernateException: Access to DialectResolutionInfo cannot be null when 'hibernate.dialect' not set
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=LATIN1spring.datasource.username=klebermospring.datasource.password=123spring.jpa.database-platform=org.hibernate.dialect.PostgreSQLDialectspring.jpa.show-sql=falsespring.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@ComponentScanpublic 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.
@SpringBootApplicationpublic 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.
I was facing a similar problem when starting up the application (using Spring Boot) with the database server down.
Hibernate can determine the correct dialect to use automatically, but in order to do this, it needs a live connection to the database.
add spring.jpa.properties.hibernate.dialect = org.hibernate.dialect.MySQLDialect
in application.properties file
