Then, in the next line, we explain to the context wherever to load its bean definitions from. Once more, setConfigLocations will be the programmatic analogous in the contextConfigLocation parameter in Net.xml
Permit’s see tips on how to configure the servlet’s context initial. We’ll take a look at some in-depth facts later on.

Annotations are employed to supply supplemental information regarding a method. It does not have a immediate effect on the operation of your code they annotate. It does not change the motion with the compiled program. Spring @Controll
Suppose that We've got two areas of our software, such as, a general public one and that is obtainable to the planet as well as a secured one with distinct MVC configurations. Listed here, we’ll just define two controllers that output a special concept.
