Spring Boot and Hibernate 5

Question

I am very new to Spring Boot. I am trying to add Hibernate 5 to my Spring Boot project and make it to work. My config class:

import org.apache.commons.dbcp.BasicDataSource;
import org.hibernate.SessionFactory;
...
import org.springframework.orm.hibernate5.HibernateTransactionManager;
import org.springframework.orm.hibernate5.LocalSessionFactoryBean;
import org.springframework.transaction.annotation.EnableTransactionManagement;

@Configuration
@EnableTransactionManagement
@ComponentScan(value = { "boot.entities" })
@PropertySources(value = { @PropertySource(value = { "classpath:db-        connection.properties", "hibernate.properties" }) })
public class Config {

@Bean
public DataSource getDataSource() {
    BasicDataSource ds = new BasicDataSource();
    ds.setUrl(env.getProperty("db.connection.url"));
    ...
    return ds;
}

@Bean
@Autowired
public LocalSessionFactoryBean getSessionFactory(DataSource dataSource) {
    LocalSessionFactoryBean sessionFactory = new LocalSessionFactoryBean();
    sessionFactory.setDataSource(dataSource);
    Properties hibernateProperties = new Properties();
    hibernateProperties.put("hibernate.dialect", env.getProperty("hibernate.dialect"));
    ...
    sessionFactory.setHibernateProperties(hibernateProperties);
    return sessionFactory;
}

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

my build.gradle file:

buildscript {
ext {
    springBootVersion = '1.4.2.RELEASE'
}
repositories {
    mavenCentral()
}
dependencies {
    classpath("org.springframework.boot:spring-boot-gradle-    plugin:${springBootVersion}")
    }
}
...
dependencies {
compile('org.springframework.boot:spring-boot-starter-actuator')
compile('org.springframework.boot:spring-boot-starter-data-jpa')
compile('org.springframework.boot:spring-boot-starter-security')
compile('org.springframework.boot:spring-boot-starter-web')
runtime('org.springframework.boot:spring-boot-devtools')
// runtime('com.h2database:h2')

// ### hibernate 5
compile group: 'org.hibernate', name: 'hibernate-core', version: '5.2.4.Final'
compile group: 'org.apache.commons', name: 'commons-dbcp2', version: '2.1.1'
compile group: 'org.apache.commons', name: 'commons-pool2', version: '2.4.2'

compile group: 'org.javassist', name: 'javassist', version: '3.21.0-GA'

testCompile('org.springframework.boot:spring-boot-starter-test')
}

and the error trying to start:

I thank you in advance for the help! And sorry for my english!

Is there a reason why you insist on using Hibernate 5.2 rather than 5.0 (the one Boot provides by default). You most probably have mixed versions of hibernate on the classpath. Also 100% of your configuration is auto-configured by Boot. You can actually remove _everything_ and use standard configuration keys for the datasource and you'll get the same thing. — Stephane Nicoll, Dec 11 '16 at 09:33
Thank you, Stephane! I am thinking in "Spring" and not according Spring Boot. I was trying to init a datasource for a Postgresql db without considering the application.properties file which to leverage on during configuration process. — peppo, Dec 11 '16 at 17:35
Well, you are using Spring Boot aren't you? There's nothing else to consider in my view. If you start a Spring Boot app you'll get that out of the box. Is there a reason why you're not considering this? — Stephane Nicoll, Dec 12 '16 at 08:06
I fear to loose control on my app. But after all you are perfectly right! — peppo, Dec 12 '16 at 13:22
Well, your app doesn't start at all right now so that's no better. And if things improve/change, you'll have to take care of that yourself. Again, that's something Spring Boot does for you, there's no reason to fight it IMO. Give it a try and feel free to create another thread if that doesn't work. — Stephane Nicoll, Dec 12 '16 at 14:40
