我想将springmvc中的数据传回到freemarker中。我自己新建了一个controler，希望用这个controler将数据传到我指定的freemarker模板路径去。但是在运行的时候，发现数据传不到指定位置去。路径是一定正确的，我怀疑有几个可能，一是没有配置好；二是代码本身的原因。谷歌也找不到好的东西（找不到应该是和我才接触有关系，弄着东西有点赶鸭子上架的感觉），这里贴出controler的代码和模板部分的关键代码。望指教
controler代码：

模板文件关键代码
[#if page.content?has_content]
[#list page.content?chunk(5) as row]
[#list row as product]
<div class="col-sm-12 col-md-12 col-lg-12 classified-goods-list" >
<div class="col-sm-2 col-md-2 col-lg-2">
<div class="classified-goods-info">
<!--<img src="/resources/shop/images/11.png">-->
<img src="${base}/upload/image/blank.gif" data-original="[#if product.image??]${product.image}[#else]${setting.defaultThumbnailProductImage}[/#if]" />
<!--商品的图片-->
<div>
<p>${abbreviate(product.name, 60)}</p><!--商品的规格信息-->
<p>已有210人购买</p><!--后台没有将人数传到freemarker-->
<p>
${currency(product.price, true)}
[#if setting.isShowMarketPrice]
[#if product.productCategory??]
[#if product.productCategory.name=="特惠活动"]
<del>${currency(product.marketPrice, true)}</del>
[/#if]
[/#if]
[/#if]
</p><!--商品的价格-->
</div>
</div>
<div class="classified-goods-cart">
<p class="text-center">加入购物车</p>
</div>
</div>
</div>
[/#list]
[/#list]
[#else]
${message("shop.product.noListResult")}
[/#if]页面的效果如下：
看着好像shop++的东西
试试这样写：
public ModelAndView handleRequest() throws Exception {
ModelAndView mv = new ModelAndView(“shop/index”);
mv.addObject("message", "Hello World!");
return mv;
}
