com.fasterxml.jackson.databind.JsonMappingException: ApplicationObjectSupport instance [org.springframework.web.servlet.view.json.MappingJackson2JsonView: unnamed] does not run in an ApplicationContext (through reference chain: java.util.HashMap["modelAndView"]->org.springframework.web.servlet.ModelAndView["view"]->org.springframework.web.servlet.view.json.MappingJackson2JsonView["applicationContext"])

    jsp
    <%@ page language="java" contentType="text/html; charset=UTF-8"
    pageEncoding="UTF-8"%>
    <!DOCTYPE html>
    <html>
    <head>
    <meta charset="UTF-8">
    <title>RequestAttribute test</title>
    </head>
    <body>
    <%
    request.setAttribute("id", 84L); request.getRequestDispatcher("/attribute/requestAttribute.do").forward (request, response);
    %>
     </body>
    </html>

и код контроллера: 

@Controller
@RequestMapping("/attribute")
public class Attribute {
    @Autowired
    private RoleService roleService = null;
    @RequestMapping("/requestAttribute")
    public ModelAndView reqAttr( @RequestAttribute("id") Long id) {
        ModelAndView mav= new ModelAndView();
        Role role = roleService.getRole(id);
        mav.addObject("role", role);
        mav.setView(new MappingJackson2JsonView());
        return mav;
    }
  }

и вывод исключения:

HTTP Status 500 - Внутренняя ошибка сервера
