On the whole, we declare several dispatcher servlets when we want numerous sets of MVC configurations. As an example, we can have a REST API along with a standard MVC software or an unsecured and safe portion of a website:
The manifest is utilized soon after the applying context is produced but prior to navigation begins to both a start out URL or possibly a deep backlink.

This interface adds a getServletContext() approach for the generic ApplicationContext interface, and defines a properly-regarded application attribute name which the root context has to be certain to while in the bootstrap method.

This file is loaded via the ContextLoaderListener which can be configured to be a context param in web.xml file. And there will be only one applicationContext for every Website application.
This permits the developer to develop intricate programs also using simple Java Lessons. The design object is often handed concerning check out and web-kontext.de controller applying maps. W
Also, based upon web application context capabilities might make your application slightly more durable to test, so you might need to employ MockServletContext course for testing.
It is same as possessing Database driver name from the context, which can not transform. In comparable way, whenever we declare contextConfigLocation param in Spring produces a single Software Context item.
Each and every DispatcherServlet has an related software context. Beans described in this kind of contexts configure the servlet and outline MVC objects like controllers and think about resolvers.
