What's new in CDI 2.0?
Before version 2.0, the CDI API was limited only to the scope of Java EE. Now and with CDI 2.0, the community did great in extending the scope of CDI into Java SE. Yes, like Spring and Google Guice, you can now use CDI in nearly any Java application.
If you are familiar enough with CDI, let's take a look at the new features that were added in CDI 2.0:
- CDI support in Java SE
- Ability to order events
- Asynchronous event
- Configurators for major SPI elements
- Possibility to configure or veto observer methods
- Add built-in annotation literals
- Make it possible to apply interceptors on producers
- Alignment on Java 8 features (streams, lambdas, repeating qualifiers)
If you are not familiar with the CDI API, don't worry. Most of the terms mentioned in this section are going to be discussed throughout the rest of the chapter.
