ztree插件的使用

//查询已存的分类值
List<Integer> cateids = storeBrandCategoryService.queryStoreCateIds(storeId);
//查询分类列表
List<Category> cateList = categoryService.queryTopCategory(cate_type);
cateLoop(cateList,cateids);
//转成josn串
JSONArray arr = JSONArray.fromObject(cateList);
String json = arr.toString();
json = json.replaceAll("cate_id", "id").replaceAll("cate_name", "name")
.replaceAll("subCategory", "nodes").replaceAll("hasCate", "checked");
mv.addObject("zTreeNodes", json);

private void cateLoop(List<Category> cateList,List<Integer> cateids){
if(cateList != null && cateList.size() > 0){
for(Category cate : cateList){
List<Category> subCate = categoryService.querysubCategory(cate);
cate.setSubCategory(subCate);
cate.setHasCate(cateids.contains(cate.getCate_id()));
cateLoop(subCate,cateids);
}
}
}
