core design concept

summary

• Domain Driven Design
• MVP architecture
• Powered by Spring Boot, Vaadin Framework8, and MyBatis

used libraries

• Lombok https://projectlombok.org/
  • do away with boilerplate code from domain model.
  • using for 2 purposes:
    • define ValueObject's getter/setter and no args constructor which Vaadin's com.vaadin.data.Binder#bind() require
    • define Aggregation's no args constructor which MyBatis's ResultMap require
  • so our domain logic don't depend on methods created by Lombok. these methods are only used by Framework.
