Contexts & Dependency Injection for Java

CDI Ecosystem

Because CDI goes well beyond standard Java EE, you'll find on this page resources of the CDI open source ecosystem. These are project or frameworks based on CDI to add high level features to your project or tools to help you develop your own CDI integration or framework. If you think a tool or framework is missing here. Feel free to contribute to this page.

Apache DeltaSpike

DeltaSpike consists of a core module and a number of optional modules for providing additional enterprise functionality to your applications.

The modules include features for enhanced security with type-safe control over method invocations, integration with schedulers, injection of CDI objects into validators, and a transactional context and scope.

DeltaSpike also provides boot and shutdown control over CDI containers in Java SE applications.

Angular Beans

Angular Beans is a powerful web framework to use AngularJS in Java EE through CDI.

Angular Beans use the power of both AngularJS and CDI to provide a lightweight but features-rich framework:

  • Transform CDI beans into injectable AngularJS services,
  • Bean validation support
  • Built-in internationalization support from server-side property files,
  • Events binding (angularJS events -> CDI events / CDI events -> angularJS events),
  • SockJS support (with auto detection) .
  • Rest style, Event driven files upload end point .
  • And a lot more...

Spring Data

spring Data makes it easy to use new data access technologies, such as non-relational databases, map-reduce frameworks, and cloud based data services.

It also provides improved support for relational database technologies. This is an umbrella project which contains many sub-projects that are specific to a given database.

All sub-projects provide support for CDI via a portable extension.

Apache Camel CDI

Apache Camel is an open source Java framework that focuses on making integration easier and more accessible to developers. It does this by providing:

  • concrete implementations of all the widely used EIPs
  • connectivity to a great variety of transports and APIs
  • easy to use Domain Specific Languages (DSLs) to wire EIPs and transports together

Camel CDI provides a Camel DSL for CDI

Metrics CDI

Metrics provides a powerful toolkit of ways to measure the behavior of critical components in your production environment.

Metrics CDI provides support for the Metrics annotations in CDI enabled environments. It implements the contract specified by these annotations with the following level of functionality:

  • Intercept invocations of bean constructors, methods and public methods of bean classes annotated with @Counted, @ExceptionMetered, @Metered and @Timed,
  • Create Gauge and CachedGauge instances for bean methods annotated with @Gauge and @CachedGauge respectively,
  • Inject Counter, Gauge, Histogram, Meter and Timer instances,
  • Register or retrieve the produced Metric instances in the resolved MetricRegistry bean,
  • Declare automatically a default MetricRegistry bean if no one exists in the CDI container.
