Event domain

Notes

• Listener of domain events are :

  • Application Services
  • Exposition Resources classes (to enjoy Spring and proxy management)

• Domain events are published from domain classes

  • Is it always true ?

Questions

• Should a DomainEvent be handle in the same transaction ?
  • Depends on business ? What are the rules ?
• What happens if a service listening for events throws an Exception ?
  • Should it rollback everything ?
  • Should it be skipped ?
  • Depends on business requirements ?
• Should an event treated asynchronously ?
• Is it a good practice to publish an event in the aggregate constructor ?
  • should it be before / after save ? Depends on what criteria ?
