Class MvcContext

java.lang.Object

io.neba.core.mvc.MvcContext

All Implemented Interfaces:

EventListener, org.springframework.context.ApplicationListener<org.springframework.context.ApplicationEvent>

public class MvcContext
extends Object
implements org.springframework.context.ApplicationListener<org.springframework.context.ApplicationEvent>

Configures a bundle-specific ApplicationContext with the Spring MVC infrastructure beans usually provided to web application contexts by the DispatcherServlet. Subsequently initializes a context-specific DispatcherServlet instance with the so configured context. The resulting dispatcher servlet is a fully-featured dispatcher servlet for the specific bundle, with the exception of event publication, which is disabled as it requires a WebApplicationContext.

The configured context may provide custom MVC infrastructure beans, e.g. by means of a <mvc:.../> XML configuration in their application context XML. Like the DispatcherServlet, the MvcContext will only provide MVC infrastructure beans if no suitable beans exist in the provided context.
