Overview

Architecture

Packages

  • ch.hszt.mdp.api Resources for the API
  • ch.hszt.mdp.dao DataAccessObject and the implementation of them (Hibernate used)
  • ch.hszt.mdp.domain Our DB-Models
  • ch.hszt.mdp.serivce A service layer to access the dao's
  • ch.hszt.mdp.util Util classes go in here
  • ch.hszt.mdp.validation All our validation classes
  • ch.hszt.mdp.web Our controller layer and therefore the mapping to the jsp's

Patterns

  • Dependency Injection is used to loosely couple the different objects. e.g. the services are get injected into the controllers by Spring.
  • Inversion of Control is used to live the framework paradigma. e.g. to encapsulate the business logic from the called methods.
  • OpenSessionInView is used so the lazy loaded objects get called if we access them from within a jsp.
