DeltaSpike、Weld与CDI

CDI      http://www.cdi-spec.org/

Weld    http://weld.cdi-spec.org/

DeltaSpike   http://deltaspike.apache.org/

 

    CDI (Contexts and Dependency Injection)是Java EE 的JCP规范（CDI 1.0 : JSR-299 , CDI 1.1,  CDI 1.2: JSR-346）。灵感来源于JBoss Seam和Google guice，也从一些框架，如Spring，借鉴学习了一些经验。

 

    Weld是CDI的参考实现。

 

DeltaSpike consist of a number of portable CDI extensions that provide useful features for Java application developers.
