Enable’s now look at how we are able to use this facility to build the identical sorts of root World-wide-web software contexts that we’ve noticed before.
That’s an summary class that, Moreover making a root World-wide-web application context as Formerly found, permits us to sign-up a person dispatcher servlet with minimal boilerplate:
The WebApplicationInitializer course that we’ve found before is usually a normal-goal interface. It seems that Spring offers a few more specific implementations, which include an summary class named AbstractContextLoaderInitializer
