  1.   

    @RequestMapping("/listProduct")
    public void listProductJson(HttpServletRequest request,
             HttpServletResponse response) throws IOException{
    response.setCharacterEncoding("UTF-8");
    response.setContentType("application/json");
    request.setCharacterEncoding("UTF-8");
    PrintWriter out = response.getWriter();
    System.out.println("OK");
    List<Product> products = productService.find("from Product");
    JSONArray json = new JSONArray();
    for(Product product:products){
    JSONObject temp = new JSONObject();
    temp.put("id", product.getId());
    temp.put("pname", product.getPname());
    temp.put("price", product.getPrice());
    json.add(temp);
    }
     out.print(json);
    }

    用FireBug调试一下，先从控制台看看后台返回的Json格式是否正确
