Going Further with CDI

Presentation material about advanced features and use cases of CDI, the Contexts and Dependency Injection standard for the Java platform.

About

This presentation introduces the CDI type and metadata SPI. It then focuses on the concept of portable extensions and covers the complete bean manager lifecycle, depicted in the diagram below. Lastly, it illustrates the use of these concepts through practical examples like the Camel CDI and Metrics CDI extensions.

Build

Environment

1. Install RVM:

   $ \curl -sSL https://get.rvm.io | bash -s stable --ruby

2. Install Bundler:

   $ gem install bundler

3. Install Graphviz and have the dot executable in the path

Instructions

1. Initialise and check out the asciidoctor-backends and dzslides submodules:

   $ git submodule update --init

2. Install the required gems:

   $ bundle install

3. Generate the HTML presentation:

   $ asciidoctor -r asciidoctor-diagram -T asciidoctor-backends/slim -a data-uri -a linkcss! slides.adoc

4. Generate the PDF presentation:

   1. Install DeckTape

   2. Export the HTML presentation:

      $ decktape dzslides slides.html slides.pdf

LiveReload

With Guard and LiveReload, you can modify the content of the presentation and have the files automatically generated and reloaded into your Web browser.

1. Install the LiveReload plugin for your Web browser (Chrome, Firefox and Safari are supported)

2. Launch Guard:

   $ bundle exec guard

3. Browse to the generated file you want to refresh and activate the LiveReload plugin (don’t forget to configure the plugin to accept refreshing local files)

Docker

Alternatively to installing Ruby and Graphviz, you can use the asciidoctor/docker-asciidoctor Docker image available on Docker Hub:

1. Run an interactive container with the documents volume bind-mounted to the working directory:

   $ docker run --rm -it -v `pwd`:/documents/ asciidoctor/docker-asciidoctor

2. Generate the HTML presentation:

   [root@... documents]# asciidoctor -r asciidoctor-diagram -T asciidoctor-backends/slim -a data-uri -a linkcss! slides.adoc
