Spring 4从休眠4迁移到5会话返回null

Question

After upgrading libs version to last and refreshing configurations session start giving null objects. I tried with different configurations, but this may be better from all. Could you help and explain what happened with upgrade?

    <spring.version>4.2.5.RELEASE</spring.version>
    <hibernate.version>5.1.0.Final</hibernate.version>  




        @Bean
        public LocalSessionFactoryBean sessionFactory() {
            final LocalSessionFactoryBean sessionFactory = new LocalSessionFactoryBean();
            sessionFactory.setDataSource(restDataSource());
            sessionFactory.setPackagesToScan(new String[]{"com.project"});
            sessionFactory.setHibernateProperties(hibernateProperties());

            return txManager;
        }

您需要确保您导入的LocalSessionFactoryBean是休眠5

org.springframework.orm.hibernate5.LocalSessionFactoryBean
