Architecture

Overview

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.
