The files of this type define configuration of an additional Spring Framework container for client blocks containing Spring MVC controllers.
A set of dispatcher-spring.xml files, including the ones defined in base projects, is declared in the cuba.dispatcherSpringContextConfig application property. File order is important, because each subsequent file can override bean configurations defined by the
previous files.
The Spring MVC controllers container is created with the main container (configured by spring.xml files) as its parent. Therefore, the beans of the controllers container can use the beans of the main container, while the beans of the main container cannot “see” the beans of the controllers container.
