Plusieurs Tomcats avec Cargo et Gradle
  • creer un repertoire dedie pour deployer le cargo dans /tmp et donner tous les droits en chmod (ecriture)
  • ne pas oublier de changer aussi le port 4200 du frontend et le port visé dans le proxy.conf.json
  • changer la valeur du env etcd pour eviter des locks sur les queues rabbits (la queue est crée a partir de cette valeur)
  • changer le nom du pool hikari
cargo {
    containerId = "tomcat9x"
    port = 8081

Hibernate Best Practices

The goal of this gist is to apply Hibernate best practices for performance purposes:

  • Use Bidirectional OneToMany relations, with Sets instead of Lists
  • Transactions should be inside Services in order to combine several DAO calls inside the same transaction
  • Using read-only transactions in order to describe when transactions should be readonly. Moreover, it improves performance and prevents non desired writes
  • Mark read-only entities a @immutable
  • Implement equals and hashcode with business key inside entities, which is useful especially for OneToMany relations

Interesting reads:
