freemarker里object集合的地图取值

freemarker里object集合的map取值

谨做笔记，以防忘记：

public class Category｛        private Long catId;private String catName;private String cateSn;｝

?

Map<String,Category> categoryMap = categoryManager.getCategoryMap();propMap.put("categoryMap",categoryMap);freeMarkerSingleton.buildHtml("goods_list.ftl", propMap, directory, htmlFileName);

?

goods_list.ftl:

<div class="position">首页 <#list navList as category>> <a href="${ctx}/goodslist/cateList-${categoryMap[category.cateSn].cateSn}/shopPrice-asc-1.jsp">${category.catName}</a></#list></div>
