public class FavoriteServlet extends ActionServlet {
private FavoriteService favoriteService = new FavoriteServiceImpl();
protected void myFavorite(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {

    response.setContentType("application/json;charset=utf-8");

    RoutePageBean routePageBean = new RoutePageBean();
    //设置一页大小
    routePageBean.setPageSize(12);

    String currentPage = request.getParameter("currentPage");
    if(currentPage != null && !currentPage.equals("")){
        routePageBean.setCurrentPage(Integer.parseInt(currentPage));
    }

    favoriteService.queryRouteByUid(request,routePageBean);

    Map<String,Object> result = new HashMap<>();

    result.put("code",0);
    result.put("msg","operation success");
    result.put("routePageBean",routePageBean);

    ObjectMapper mapper = new ObjectMapper();
    String s = mapper.writeValueAsString(result);
    response.getWriter().write(s);
