AJDT Demos

Demonstration: Developing with AspectJ and AJDT

This demonstration shows the use of AspectJ and AJDT to
refactor a crosscutting concern (view notification) in a simple
insurance application. The demo is about 18MB in size (split
into four parts), and includes an audio commentary.

• 
  In part 1, we introduce the insurance
  application and show you how to
  convert an existing Java project in the Eclipse workspace to an
  AspectJ project. We also demonstrate how to create a new aspect using
  the New Aspect Wizard.
  
• 
  
  
  In part 2, we show how to use the
  declare warning
  construct to find all the places in the Insurance application
  concerned with view notification.
  
• 
  
  In part 3, the implementation of view
  notification is modularized
  in the aspect, and we show you how to use the AspectJ Development
  Tools (AJDT) to navigate around the structure of the program.
  
• 
  
  In part 4, we complete the
  implementation by ensuring that the
  test suite still passes, and leave behind a guard so that the
  modular implementation of view notification we just put in place
  cannot be accidently comprised by subsequent program maintenance.
