GSON解析凍結

Question

我有這個以.json類型

{"paging":{"page":1,"total":2015,"page_size":20,"pages":101}, 

"loans":[ 
    { 
    "id":519729, 
    "name":"Hefseba Group", 
    "description":{"languages":["en"]}, 
    "status":"fundraising", 
    "funded_amount":3125, 
    "basket_amount":0, 
    "image":{"id":1280581,"template_id":1}, 
    "activity":"Cafe", 
    "sector":"Food", 
    "use":"to buy more stock for her cafe, and to buy more fabrics and liquid soap.", 
    "location":{"country_code":"TZ", 
    "country":"Tanzania", 
    "geo":{"level":"country","pairs":"-6 35","type":"point"}}, 
    "partner_id":87, 
    "posted_date":"2013-02-01T09:14:17Z", 
    "planned_expiration_date":"2013-03-03T09:14:17Z", 
    "loan_amount":4025, 
    "borrower_count":16 
    }, 

    { 
    "id":520550,"name":"Waridi Pendo Group", 
    "description":{"languages":["en"]}, 
    "status":"fundraising", 
    "funded_amount":800, 
    "basket_amount":0, 
    "image":{"id":1282077,"template_id":1}, 
    "activity":"Music Discs & Tapes", 
    "sector":"Retail", 
    "use":"to buy music equipment and DVDs and CDs, as well as to start building his house. ", 
    "location":{"country_code":"TZ", 
    "country":"Tanzania", 
    "geo":{"level":"country","pairs":"-6 35","type":"point"}}, 
    "partner_id":87, 
    "posted_date":"2013-02-01T09:18:11Z", 
    "planned_expiration_date":"2013-03-03T09:18:11Z", 
    "loan_amount":6100, 
    "borrower_count":11 
    } 
] 

} 

然後，我有這樣的代碼試圖解析它。

try{ 
    JsonReader runThrough = getJsonReader(fileName); 
    System.out.println("File found"); 
    Gson myGson = new Gson(); 
    JsonParser jsonParser = new JsonParser(); 
    JsonArray infoArray = jsonParser.parse(runThrough).getAsJsonArray(); 
    System.out.println("Finished Parsing"); 
    for (JsonElement piece : infoArray){ 

    } 
} catch (Exception e){ 
    System.out.println(e); 
} 

我希望每個貸款最終被保存到kLoan的ArrayList，但我只是有一個空循環現在。錯誤我得到這一行凍結：

JsonArray infoArray = jsonParser.parse(runThrough).getAsJsonArray(); 

Answer 1

1. 這不是一個有效的JSON文件。所以也許這就是解析器卡住的原因。有關詳細信息，請使用JSON lint。有一個逗號缺失。

2. 整體對象不是數組。你需要獲得房產貸款，並調用此方法getAsJsonArray方法。像這樣：

   try{ 
       JsonReader runThrough = getJsonReader(fileName); 
       System.out.println("File found"); 
       Gson myGson = new Gson(); 
       JsonParser jsonParser = new JsonParser(); 
       JsonObject jsonObj = jsonParser.parse(runThrough).getAsJsonObject(); 
       JsonArray infoArray = jsonObj.getAsJsonArray("loans"); 
       System.out.println("Finished Parsing"); 
       for (JsonElement piece : infoArray){ 
   
       } 
   } catch (Exception e){ 
       System.out.println(e); 
   }
