使用列表填充jTable

我有從Json文件中使用Json Jackson獲得的數據列表，我如何從這個列表填充jTable？使用列表填充jTable

[{"id":1,"name":"Bambola","description":"Opis...","contact_number":"022\/349-499","email":"","address":"Svetosavksa 23","geo_latitude":"44.96868000000000","geo_longitude":"20.28140000000000","created_at":"2013-06-24 14:15:08","updated_at":"2013-06-24 14:15:08","deleted_at":null,"publication_starts":"1991-05-24 01:00:00","publication_ends":"1991-05-24 01:00:00"},{"id":2,"name":"Master","description":"Opis...","contact_number":"022\/349-123","email":"","address":"Svetosavksa 24","geo_latitude":"44.96653000000000","geo_longitude":"20.28170000000000","created_at":"2013-06-24 14:15:08","updated_at":"2013-06-24 14:15:08","deleted_at":null,"publication_starts":"0000-00-00 00:00:00","publication_ends":"0000-00-00 00:00:00"},{"id":3,"name":"Tritel","description":"Opis...","contact_number":"022\/321-499","email":"","address":"Svetosavksa 25","geo_latitude":"44.96654000000000","geo_longitude":"20.28170000000000","created_at":"2013-06-24 14:15:08","updated_at":"2013-06-24 14:15:08","deleted_at":null,"publication_starts":"0000-00-00 00:00:00","publication_ends":"0000-00-00 00:00:00"}]

使用Json Jackson解析器我已經使用此數據填充List。

List<Advertisement> advertisements = mapper.readValue(url, new TypeReference<List<Advertisement>>(){});

現在我想填充jTable，我已經使用NetBeans GUI生成器來創建框架和表格。表名是advertisementList_JT。到目前爲止，我嘗試的是這個網站上的一個類似問題的代碼片段。

DefaultTableModel model = new DefaultTableModel(); 
     for (Advertisement adv : advertisements) { 
      Object[] o = new Object[3]; 
      o[0] = adv.getName(); 
      o[1] = adv.getPublication_starts(); 
      o[2] = adv.getPublication_ends(); 
      model.addRow(o); 
     } 
     advertisementList_JT.setModel(model);

在這個片段表時我啓動應用程序只是去灰，什麼也沒有發生，看着直通調試器，沒有錯誤或者。

看看AbstractTableModel，這裏是最近兩個月的一些非常好的嘗試 – mKorbel

你發佈的基本代碼看起來很好，但我們不知道代碼被調用的上下文。如果框架是灰色的，那麼我會建議你不要將表格添加到框架中。也許你有實例和局部變量。添加一些調試語句給你的代碼看看你的代碼是否被執行。 – camickr

@mKorbel：你爲什麼不喜歡DefaultTableModel？大多數表格不需要自定義表格模型。 –

我認爲這是因爲你沒有提供表頭。看看是否有效：

Object[] columnNames = {"Name", "Starts", "Ends"}; 
DefaultTableModel model = new DefaultTableModel(new Object[0][0], columnNames); 
     for (Advertisement adv : advertisements) { 
      Object[] o = new Object[3]; 
      o[0] = adv.getName(); 
      o[1] = adv.getPublication_starts(); 
      o[2] = adv.getPublication_ends(); 
      model.addRow(o); 
     } 
     advertisementList_JT.setModel(model);

另一種可能性是廣告列表是空的;

是的，它的工作非常感謝。列名是T問題，如果我在GUI構建器中編寫了列名稱，它們將應用到表中，它看起來像.setModel，我替換了以前使用GUI BUilder完成的所有配置。 –
