我有一個(gè) json 文件，其格式為：{ "results": [ { "quiz": "1112??? ??? ??? ???? ??? ?????? ", "answer": " X " }, { "quiz": "16?? ? ???? ???? ??? ???, ?? ?? ?? ??? ??? ", "answer": " X " }, { "quiz": "1769? ????? ???? ?? ??? ", "answer": "??" } ]}我想在JAVA區(qū)獲取這個(gè)文件。我有一個(gè)依賴(lài)項(xiàng)com.googlecode.json-simple(1.1.1 version)，我有一個(gè)我寫(xiě)的代碼拋出異常:(public List<CheatImported> importJsonFile(String path) throws IOException, FileNotFoundException, ParseException { JSONObject root = (JSONObject)jsonParser.parse(new FileReader(path)); JSONArray results = (JSONArray)root.get("results"); @SuppressWarnings("rawtypes") Iterator iter = results.iterator(); List<CheatImported> resultList = new ArrayList<CheatImported>(); while(iter.hasNext()){ JSONObject item = (JSONObject)iter.next(); String question = (String)item.get("quiz"); String answer = (String)item.get("answer"); CheatImported imported = new CheatImported(); imported.setQuestion(question); imported.setAnswer(answer); resultList.add(imported); } return resultList; }ArrayList 的類(lèi)型是一個(gè)只有兩個(gè)字符串屬性的類(lèi)：@Getter@Setter@NoArgsConstructorpublic class CheatImported { private String question; private String answer;}這是我的junit代碼：@Test public void cheatImported() throws Exception{ String path = "D:\\workspace_orderByDate\\20180105\\moonBladeQuiz\\src\\main\\resources\\static\\data.json"; List<CheatImported> list = importService.importJsonFile(path); assertTrue(list.size() > 0); }
