Spring Boot instantly configures the components of the applying, so, typically, There exists a lot less want to consider how to prepare them.
The WebApplicationInitializer course that we’ve viewed earlier is often a typical-objective interface. It turns out that Spring delivers several much more certain implementations, including an summary class known as AbstractContextLoaderInitializer
