Introduction to Contexts and Dependency Injection for the Java EE Platform
Contexts and Dependency Injection (CDI) for the Java EE platform is one of several Java EE 6 features that help to knit together the web tier and the transactional tier of the Java EE platform. CDI is a set of services that, used together, make it easy for developers to use enterprise beans along with JavaServer Faces technology in web applications. Designed for use with stateful objects, CDI also has many broader uses, allowing developers a great deal of flexibility to integrate various kinds of components in a loosely coupled but typesafe way.
CDI is specified by JSR 299, formerly known as Web Beans. Related specifications that CDI uses include the following:
- JSR 330, Dependency Injection for Java
- The Managed Beans specification, which is an offshoot of the Java EE 6 platform specification (JSR 316)
The following topics are addressed here:
