As we can easily see, the controllers lie in two different deals web-kontext.de and print different messages: a single suggests “usual”, and another says “protected”.
The WebApplicationInitializer course that we’ve seen previously is often a typical-goal interface. It turns out that Spring provides a couple of far more certain implementations, together with an summary class named AbstractContextLoaderInitializer
As we’ve noticed previously, we really have to apply the onStartup strategy. Even so, this time we’ll make and register a dispatcher servlet, too:
