I previously was using Spring Boot 1.4.2.RELEASE and Hibernate 5.0.11.Final, and this was my Database configuration class:

@Configuration
@EnableTransactionManagement
public class DataBaseConfiguration {

    @Bean(name = "sessionFactory")
    public HibernateJpaSessionFactoryBean sessionFactory() {
        return new HibernateJpaSessionFactoryBean();
    }

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

and this is application.yml:

spring:
    application:
        name: test
    profiles:
        active: dev
    datasource:
        type: com.zaxxer.hikari.HikariDataSource
        url: jdbc:mysql://localhost:3306/test?useUnicode=yes&characterEncoding=utf8&useSSL=false
        username: test
        password: test
        hikari:
          maximum-pool-size: 50
          data-source-properties:
                pool-name: test
                cachePrepStmts: true
                prepStmtCacheSize: 250
                prepStmtCacheSqlLimit: 2048
                useServerPrepStmts: true
    jpa:
        open-in-view: true
        database-platform: org.hibernate.dialect.MySQL5InnoDBDialect
        database: MYSQL
        show-sql: true
        properties:
            hibernate.enable_lazy_load_no_trans: true
            hibernate.cache.use_second_level_cache: true
            hibernate.cache.use_query_cache: false
            hibernate.generate_statistics: true
            hibernate.dialect: org.hibernate.dialect.MySQL5Dialect
            hibernate.current_session_context_class: org.springframework.orm.hibernate5.SpringSessionContext
            hibernate.hbm2ddl.auto: update

and this is GenericRepository class:

@Repository
public abstract class GenericRepository<T extends BaseEntity, PK extends Serializable> implements IGenericRepository<T, PK> {
    protected Class<T> domainClass = getDomainClass();

    protected abstract Class<T> getDomainClass();

    @Autowired
    SessionFactory sessionFactory;

    public Session getSession() {
        try {
            return sessionFactory.getCurrentSession();
        }
        catch (Exception e) {
            log.error(e.getMessage());
        }
        return sessionFactory.openSession();
    }

    @Override
    public void add(T entity) {
        Session session = getSession();
        session.save(entity);
    }

    // Other DAO layer methods here, removed for brevity
}

and this is dependencies part of pom.xml:

<dependencies>
    <dependency>
        <groupId>mysql</groupId>
        <artifactId>mysql-connector-java</artifactId>
    </dependency>

then, I changed Spring Boot version to 1.5.9.RELEASE and Hibernate version to 5.2.12.Final and then when I run the application, got this exception:

Finally, when I checked the DataBaseConfiguration class after above version changes, I saw that HibernateJpaSessionFactoryBean is deprecated.

Then I checked other question that was same this problem, but didn't find any solution. How should I change my configurations in order to get application started?

The javadoc seems to propose an alternative due to the deprecation:

And as of JPA 2.1, EntityManagerFactory.unwrap(java.lang.Class<T>) provides a nice approach as well, in particular within configuration class arrangements:

 @Bean
 public SessionFactory sessionFactory(
         @Qualifier("entityManagerFactory") EntityManagerFactory emf) {
     return emf.unwrap(SessionFactory.class);
 }

And a word of caution:

Please note: Since Hibernate 5.2 changed its SessionFactory interface to extend JPA's EntityManagerFactory, you may get conflicts when injecting by type, with both the original factory and your custom SessionFactory matching EntityManagerFactory. An explicit qualifier for the original factory (as indicated above) is recommended here.

I am using Hibernate 5.2 with sessionfactory with this configuration 

@Configuration
@EnableTransactionManagement
public class DatabaseConfiguration {

    @Inject
    public JpaProperties prop;

    @Bean
    @Primary
    @ConfigurationProperties("spring.datasource.hikari")
    public DataSourceProperties dataSourceProperties() {
        return new DataSourceProperties();
    }

    @Bean
    @Primary
    @ConfigurationProperties("spring.datasource.hikari")
    public DataSource dataSource() {
        return dataSourceProperties().initializeDataSourceBuilder().build();
    }


    @Bean("sessionFactory")
    @Primary
    public LocalSessionFactoryBean getSessionFactory() {
        LocalSessionFactoryBean sessionFactory = new LocalSessionFactoryBean();
        sessionFactory.setDataSource(dataSource());
        sessionFactory.setPackagesToScan("org.roshan");
        sessionFactory.setAnnotatedPackages("org.roshan");
        sessionFactory.setHibernateProperties(getHibernateProperties());
        return sessionFactory;
    }

    private  Properties getHibernateProperties() {
        Properties p = new Properties();
        p.putAll(prop.getProperties());
        p.put(AvailableSettings.HBM2DDL_AUTO, prop.getHibernate().getDdlAuto());
        return p;
    }


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

}

my POM.xml properties 

<properties>
    <maven.compiler.source>1.8</maven.compiler.source>
    <maven.compiler.target>1.8</maven.compiler.target>
    <hibernate.version>5.2.10.Final</hibernate.version>
</properties>
