SPRINGMVC configuration uses a lot of articles, but the specific description is not much, here the main introduction of the use of common configuration items, and its parsing class, SPRINGMVC processing content in two ways, one is converter, the other is Viewresolver, Both can handle json,xml and form content formats.
