Usage

From source file:co.paralleluniverse.springframework.web.servlet.mvc.method.annotation.FiberRequestMappingHandlerAdapter.java

/**
 * Invoke the {@link RequestMapping} handler method preparing a {@link ModelAndView}
 * if view resolution is required./*from   w  w  w. j  a  v a 2  s. c o  m*/

private ModelAndView invokeHandleMethod(HttpServletRequest request, HttpServletResponse response,
        HandlerMethod handlerMethod) throws Exception {
