FastJosn轉化JSON字符串有多餘轉移符的情況解決

FastJosn轉化JSON字符串有多餘轉移符的情況解決

首先我說明前提情況：是因爲你轉換了一個本來就是一個 json格式的字符串，所以他會加上轉義，話不多說直接上解決方案

public static void main(String[] args) {
        List<Map<String,Object>> list = new ArrayList<>();

        Map<String,Object> map = new HashMap<String,Object>(){
            {
                put("123",new Date());
                put("name","張三");
                put("sex","男");
                put("age",12);
                put("haha","哈哈");
            }
        };
        Map<String,Object> map1 = new HashMap<String,Object>(){
            {
                put("123",new Date());
                put("name","張三");
                put("sex","男");
                put("age",12);
                put("haha","哈哈");
            }
        };
        Map<String,Object> map2 = new HashMap<String,Object>(){
            {
                put("123",new Date());
                put("name","張三");
                put("sex","男");
                put("age",12);
                put("haha","哈哈");
            }
        };

        list.add(map);
        list.add(map1);
        list.add(map2);
        JSONObject.DEFFAULT_DATE_FORMAT = "yyyy-MM-dd";
        final String string = JSON.toJSONString(list, SerializerFeature.WriteDateUseDateFormat);

        final Map<String,Object> res = new HashMap<String,Object>(){


            {
                put("res",JSON.parse(string));
                put("code","200");
            }
        };

        System.out.println(JSON.toJSONString(res));
    }

把字符串重新轉成object後再進行json轉換 JSON.parse(string)
