Context and Dependency Injection (CDI 1.1)

Antonio Goncalves

Learn how to decouple and inject your components with CDI (Context and Dependency Injection) in your Java SE and Java EE applications.

Context and Dependency Injection takes its roots from injection frameworks and today has become a common ground for several Java EE specifications. In this course you will discover the CDI programming model and its concept of "loose coupling, strong typing." You will see that decoupling goes further by bringing interceptors and decorators to the entire platform.
