Spring Boot 2.0.0 M6 - Add Hibernate Interceptor

After upgrade from Spring Boot 2.0.0 M2 to 2.0.0 M6 my Hibernate interceptor implementation don't work anymore.

My old implementation:

@Configuration
public class HibernateConfiguration extends HibernateJpaAutoConfiguration {

    private HibernateStatisticsInterceptor hibernateStatisticsInterceptor;

    public HibernateConfiguration(DataSource dataSource, JpaProperties jpaProperties, ObjectProvider<JtaTransactionManager> jtaTransactionManager, ObjectProvider<TransactionManagerCustomizers> transactionManagerCustomizers, ObjectProvider<List<SchemaManagementProvider>> providers, HibernateStatisticsInterceptor hibernateStatisticsInterceptor) {
        super(dataSource, jpaProperties, jtaTransactionManager, transactionManagerCustomizers, providers);
        this.hibernateStatisticsInterceptor = hibernateStatisticsInterceptor;
    }

    @Override
    protected void customizeVendorProperties(Map<String, Object> vendorProperties) {
        vendorProperties.put("hibernate.session_factory.interceptor", hibernateStatisticsInterceptor);
    }
}

But with M5 or M6 the HibernateJpaAutoConfiguration class changed and extends JpaBaseConfiguration no more.

I try to add my interceptor per YAML-Configuration file, but it's not working.

My Interceptor:

@Component("hibernateStatisticsInterceptor")
public class HibernateStatisticsInterceptor extends EmptyInterceptor {

    private static final long serialVersionUID = 5278832720227796822L;

    private ThreadLocal<Long> queryCount = new ThreadLocal<>();

    public void startCounter() {
        queryCount.set(0l);
    }

    public Long getQueryCount() {
        return queryCount.get();
    }

    public void clearCounter() {
        queryCount.remove();
    }

    @Override
    public String onPrepareStatement(String sql) {
        Long count = queryCount.get();
        if (count != null) {
            queryCount.set(count + 1);
        }
        return super.onPrepareStatement(sql);
    }

}

How can I reactivate my interceptor?

Thanks for any hints

regards Rizzi

I can solve this with this documentation:

Add support for advanced customization of Hibernate settings

Just implements a interface HibernatePropertiesCustomizer

and implements methods customize(Map<String, Object> hibernateProperties)

@Component
class MyHibernateInterceptorCustomizer implements HibernatePropertiesCustomizer {

    @Autowired
    MyInterceptor myInterceptor

    @Override
    void customize(Map<String, Object> hibernateProperties) {
       hibernateProperties.put("hibernate.session_factory.interceptor", myInterceptor);
    }
}

Hello,

Give this a read: https://github.com/spring-projects/spring-boot/commit/59d5ed58428d8cb6c6d9fb723d0e334fe3e7d9be (use: HibernatePropertiesCustomizer interface)

  1. Implement it.
  2. @Override customize() method, add your interceptor
  3. Don't forget to @Lazy inject in case of internal beans
  4. Done => Run

Hope this was of use to you.

As a final note: always update your Spring / Hibernate versions (use the latest as possible) and you will see that most code will become redundant as newer versions try to reduce the configurations as much as possible.

As https://github.com/spring-projects/spring-boot/issues/11211 has been resolved, HibernatePropertiesCustomizer can be used since Spring Boot 2.0.0.RC1 (not released at the moment of writing yet but snapshots are available now).
