  • Title

    • Title - Building CDI Extensions using Apache DeltaSpike

    • Presenter - Jason Porter Senior Software Engineer, JBoss by Red Hat

    • web address - if I get it all setup lightguardjp.info

  • CDI Intro

    • What does CDI do for us?

      • discover and resolve beans

      • manage a bean’s lifecycle

      • injection

      • bind a bean to a context

      • Strong typing

      • loose coupling

      • bean metadata

    • What is life like without CDI?

      • new …​.() / reflection

      • loose typed injection (Seam 2, Spring, etc)

      • JNDI lookup

      • Session or Request lookup / storage

      • Tight coupling to libraries

    • What is life like with CDI?

      • Minimal configuration

      • Compiler checked mistakes

      • Fail Fast - deploy time

      • Standard injection

      • Multiple Scopes

      • Very loose coupling to libraries

    • How does it improve the development experience?

      • Very quick ramp up

      • Great tooling

        • IntelliJ

        • JBoss Tools

        • NetBeans

      • Simplicity

        • @Inject

        • @Produces

      • Useful at all stages

        • Development

        • Testing

        • Production

        • Alternatives, Scopes

      • Improved productivity

        • Interceptors

        • Decorators

        • Eventing

        • Quick feedback

  • What’s the Best part?

    • What isn’t there: Extensions

    • Scopes

    • 3rd Party Integration

    • Anything you can code

  • CDI Extensions

    • Explanation & what you can do

      • register additional beans

      • satisfy injection points

      • create new scopes with backings

      • modify bean metadata

    • How do Extensions work

    • Application lifecycle of a CDI Application and callbacks (look into CSS arrows)

      • Deploy Application

      • BeforeBeanDiscovery

      • Scan Archives

      • ProcessAnnotedTypes

      • ProcessInjectionTargets

      • ProcessBeans

      • ProcessProducers

      • ProcessObserverMethods
