package com.pure.web.spring;

import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;

import org.springframework.web.servlet.ModelAndView;
import org.springframework.web.servlet.mvc.Controller;

import com.pure.domain.Dish;
import com.pure.domain.logic.DishFacade;
import com.pure.util.ParamUtil;

public class ViewDishController implements Controller {
	private DishFacade dishFacade;
	
	private String successView;
	
	public DishFacade getDishFacade() {
		return dishFacade;
	}

	public void setDishFacade(DishFacade dishFacade) {
		this.dishFacade = dishFacade;
	}

	public ModelAndView handleRequest(HttpServletRequest request,
			HttpServletResponse response) throws Exception {
		int id = ParamUtil.getInt(request,"dishId");
		Dish dish = dishFacade.getDish(id);
		return new ModelAndView(this.getSuccessView(), "dishItem", dish);
	}

	public String getSuccessView() {
		return successView;
	}

	public void setSuccessView(String successView) {
