CDI Scopes One-pager

· Java Zone

Discover how AppDynamics steps in to upgrade your performance game and prevent your enterprise from these top 10 Java performance problems, brought to you in partnership with AppDynamics.

While figuring out what CDI scope to use for a particular bean, it is sometimes helpful to have a brief one pager like the one put together by Goncalo Marques. The page lists out various CDI scopes, very briefly explains each as well as making mention of proxies and serialization. Although the page is mostly geared towards Java EE 6 and does not yet mention the changes in Java EE 7 such as CDI compatible @ViewScoped@FlowScoped and @TransactionScoped, the page is still worth bookmarking.

More generally speaking for CDI, there are a number of very good references available such as the very well written Weld reference guide, the CDI portion of the official Java EE Tutorial as well as the spec itself (perhaps one of the most readable Java EE specs around).

The Java Zone is brought to you in partnership with AppDynamics. AppDynamics helps you gain the fundamentals behind application performance, and implement best practices so you can proactively analyze and act on performance problems as they arise, and more specifically with your Java applications.
