Well, if you happen to use Spring it's doable with low effort:

• create a Spring factory bean that returns the Hibernate statistics bean from the session factory

  public class HibernateStatisticsFactoryBean implements FactoryBean<Statistics> {
  
    @Autowired
    private EntityManagerFactory entityManagerFactory;
  
    @Override
    public Statistics getObject() throws Exception {
      SessionFactory sessionFactory = ((HibernateEntityManagerFactory) entityManagerFactory).getSessionFactory();
      return sessionFactory.getStatistics();
    }
  
    @Override
    public Class<?> getObjectType() {
      return Statistics.class;
    }
  
    @Override
    public boolean isSingleton() {
      return true;
    }
  }
  

• use the MBeanExport to export the above factory bean: http://docs.spring.io/spring/docs/3.2.x/spring-framework-reference/html/jmx.html#jmx-mbean-server
