What’s new in CDI 4.0 ? by Antoine Sabot Durand

Jakarta Contexts and Dependency Injection is probably the most underrated specification around. It is the Jakarta EE and MicroProfile corner stone since it provides a standard programming model and a powerful to integrate third party technology in a seamless way. Now that major work on CDI 4.0 is nearly over (waiting for Jakarta EE 10 release), it’s interesting to list the evolution of the spec in the last year. In this talk we’ll go thru all new and corrected features in the specification and will make a big focus on CDI lite that will enhance CDI spec to better support build time framework like Quarkus. We’ll go thru the new portable extension API with a concrete example, and we’ll see how it differs from legacy runtime portable extension. You’ll leave the talk being able to develop CDI Lite extension for your favorite framework integrating it to the CDI programming model.
