Web MVC Config

See equivalent in the Reactive stack

Applications can declare the infrastructure beans listed in Special Bean Types that are required to process requests. The DispatcherServlet checks the WebApplicationContext for each special bean. If there are no matching bean types, it falls back on the default types listed in DispatcherServlet.properties.

In most cases, the MVC Config is the best starting point. It declares the required beans in either Java or XML and provides a higher-level configuration callback API to customize it.
