If we want to use an annotation-centered context, we could alter the code snippet in the earlier segment to make it instantiate an AnnotationConfigWebApplicationContext
Going back again to Servlet days, World wide web.xml might have only one , so just one context item will get designed when server masses an application and the data in that context is shared amid all sources (Ex: Servlets and JSPs).

I've heard that there are two different types of contexts also employed for an internet-application. A single serves as as root software context wherever non-web linked definitions are delivered illustration provider, dao configurations etc, and another is for World wide web-specific configuration like Handler Mappings and many others.
Aid for generic web-kontext.de ask for context Keeping, specifically for scoping of software objects per HTTP ask for or HTTP session.
This enables the developer to create complex applications also employing simple java courses. The model item might be handed between perspective and controller applying maps. I
