Examples of org.springframework.web.servlet.HandlerAdapter

org.springframework.web.servlet.HandlerAdapter
MVC framework SPI interface, allowing parameterization of core MVC workflow.
Interface that must be implemented for each handler type to handle a request. This interface is used to allow the DispatcherServlet to be indefinitely extensible. The DispatcherServlet accesses all installed handlers through this interface, meaning that it does not contain code specific to any handler type.
Note that a handler can be of type Object. This is to enable handlers from other frameworks to be integrated with this framework without custom coding.
This interface is not intended for application developers. It is available to handlers who want to develop their own web workflow.
Note: Implementations can implement the Ordered interface to be able to specify a sorting order and thus a priority for getting applied by DispatcherServlet. Non-Ordered instances get treated as lowest priority. @author Rod Johnson @author Juergen Hoeller @see org.springframework.web.servlet.mvc.SimpleControllerHandlerAdapter @see org.springframework.web.servlet.mvc.throwaway.ThrowawayControllerHandlerAdapter @see org.springframework.web.servlet.handler.SimpleServletHandlerAdapter
