It inherits its characteristics from Spring Beans and adds help for internationalization, function propagation, source loading, as well as transparent creation of contexts.
. So, we can have just one AbstractContextLoaderInitializer and plenty of AbstractDispatcherServletInitializer implementations that don’t make a root context. In this kind of situation, it is sensible to order the initializers with @Order
This two degree separation arrives out in the box when you utilize the spring servlet courses: to configure the foundation software context you must use context-param

Spring MVC apps have at the very least one Dispatcher Servlet configured (but potentially more than one, we’ll mention that circumstance later). This can be the servlet that receives incoming requests, dispatches them to the appropriate controller process, and returns the check out.
As we can easily see, the controllers lie in two unique deals and print distinct messages: one suggests “typical”, and another says “protected”.
