JSON類型的String轉成List

//后端調用接口 
List<String> directives = new ArrayList<>();
 while (matcher.find()) {
     directives.add(matcher.group(1));
     LOGGER.info("處理標簽：{}", matcher.group(1));
 }
 JSONObject jsonObject = new JSONObject();

 Map map2=new HashMap();
//將List<String> 轉為JSON存儲 放入map中
 map2.put("marksList",JSON.toJSONString(directives));
 map2.put("userId","SU000000000195");
 JSONObject obj2 =  PostInterface.post(PostInterface.ServletName.placeholder,"queryPlaceHolderByMarks",map2).getJSONObject("SvcCont");
 List<Placeholder> pList = JSON.parseArray(obj2.getString("placeHolderList"),Placeholder.class);

 

//接口中解析

JSON中string轉List<String>
List<String> pList = JSON.parseArray(svcCont4PlaceHolderReq.getMarksList(),String.class);
