后台返回字典类型的数据给前台

当后台返回的数据不是json而是map集合的时候，前端js中处理就将其看作是一个数组，例如后台返回的代码入下：

Map<String, String> result = new HashMap<String, String>();
map.put("code", "200");
map.put("title", result.get("title"));
map.put("content", result.get("content"));
return map;

 

前端处理时，直接以数组的形式输出即可，代码如下：

             if(data["code"]=="200"){
                var title =data["title"];
                var content = data["content"];
                alert(title);
                alert(content);
            }

 

其中data即为后台返回的Map集合

 

 

后台处理，为下拉框

Map<String, Object> objmap = new HashMap<>();

        Map<String, String> map = picklistEnum.getMap();
        for (String in : map.keySet()) {

            if(!in.equals("NationalIDCardType")){
                QueryWrapper<ThPickList> queryWrapper = new QueryWrapper<ThPickList>(new ThPickList());
                queryWrapper.eq("name",in);
                //status为A的数据
                queryWrapper.eq("status","A");
                List<ThPickList> thPickLists = baseMapper.selectList(queryWrapper);
                List<ShowPickList> ll = new ArrayList<>();
                if(in.equals("Gender")||in.equals("PositionType")){
                    for (ThPickList thPickList : thPickLists) {

                objmap.put(in,ll.stream().sorted(Comparator.comparing(ShowPickList::getlValue) ).collect(Collectors.toList()));
