Class HibernateStatisticsConfig

java.lang.Object
com.alpaca.config.HibernateStatisticsConfig
@Configuration public class HibernateStatisticsConfig extends Object
Configures and enables Hibernate statistics for performance monitoring.

This configuration class activates Hibernate's internal statistics collection, which can be useful for diagnosing performance issues, such as identifying slow queries or excessive database hits. Enabling statistics allows access to detailed metrics about session activity, query execution, cache usage, and more.

While Hibernate statistics are typically disabled in production environments due to their potential impact on performance, they can be invaluable during development and testing phases. To enable statistics in a Spring Boot application, set the following property in your application.properties or application.yml: 

 spring.jpa.properties.hibernate.generate_statistics=true

Additionally, to log detailed statistics, you can adjust the logging level: 

 logging.level.org.hibernate.stat=DEBUG

For more information on enabling and using Hibernate statistics, refer to the following resources:

      private final jakarta.persistence.EntityManagerFactory entityManagerFactory
      Interface used to interact with the entity manager factory for the persistence unit.

  • Method Details

    • enableStatistics

      @PostConstruct public void enableStatistics()
      Enables Hibernate statistics after the bean initialization.

      This method unwraps the EntityManagerFactory to obtain the underlying SessionFactory, then enables its statistics feature. This allows for the collection of various performance metrics, such as query counts, cache hits, and session activity, which can be useful for performance tuning and analysis.

      Note: Enabling statistics can have a performance overhead. It is recommended to enable them only in development or testing environments.
