fastJSON List对象 Map对象与JSON对象的互转

 List<SysUser> suList = new ArrayList<>();        Map<String,Object> suMap = new HashMap<>();        for(int i = 0 ; i<3; i++){            SysUser su = new SysUser();            su.setId(1);            su.setRoleId(2);            su.setUserPhone("phone"+i);            suList.add(su);        }        //Map对象转成JSON对象        suMap.put("suList",suList);        JSONObject ms = JSONObject.parseObject(JSONObject.toJSONString(suMap));        JSONArray suListMap = ms.getJSONArray("suList");        String suListMapStr = suListMap.toString();        System.out.println("Map对象转换后的字符串="+suListMapStr);        //List对象转成JSON对象        JSONArray js = JSONArray.parseArray(JSONObject.toJSONString(suList));        String s = js.toJSONString();        System.out.println("List对象转换后的字符串="+s);//        //JSONObject 转化成List对象        ArrayList<SysUser> suArr = JSON.parseObject(s,new TypeReference<ArrayList<SysUser>>(){});        System.out.println("JSONObject 转化成List对象"+suArr.size());
