In org.springframework.orm.hibernate5.LocalSessionFactoryBean, there is a variable argument setter method for hibernateIntegrators which will accept one or more instances of org.hibernate.integrator.spi.Integrator

So in org.springframework.orm.hibernate5.LocalSessionFactoryBean configuration add the below property

and make the Integrator as managed bean

    package com.test.ttv;
    import org.hibernate.boot.Metadata;
    import org.hibernate.boot.model.relational.Database;
    import org.hibernate.engine.spi.SessionFactoryImplementor;
    import org.hibernate.service.spi.SessionFactoryServiceRegistry;
    import org.springframework.stereotype.Component;

    @Component  
    public class MetadataExtractorIntegrator implements org.hibernate.integrator.spi.Integrator {

        private Database database;

        private Metadata metadata;

        public Database getDatabase() {
            return database;
        }

        public Metadata getMetadata() {
            return metadata;
        }

        @Override
        public void integrate(
                Metadata metadata,
                SessionFactoryImplementor sessionFactory,
                SessionFactoryServiceRegistry serviceRegistry) {

            this.database = metadata.getDatabase();
            this.metadata = metadata;

        }

        @Override
        public void disintegrate(
            SessionFactoryImplementor sessionFactory,
            SessionFactoryServiceRegistry serviceRegistry) {

        }
    }
