誰能幫助我從谷歌電子表格在JAVA

Question

我想下面的代碼從谷歌電子表格中讀取數據，但得到讀取數據時出錯..任何人都可以幫助我從谷歌電子表格中取數據

public class gsheet 
{ 
    public static final String GOOGLE_ACCOUNT_USERNAME = "gmail-id"; 
    public static final String GOOGLE_ACCOUNT_PASSWORD = "password"; 
    public static final String SPREADSHEET_URL = "spread-sheet-URL"; 


     public static void main(String[] args) throws IOException, ServiceException 
     { 
     SpreadsheetService service = new SpreadsheetService("JAVA"); 
     service.setUserCredentials(GOOGLE_ACCOUNT_USERNAME, GOOGLE_ACCOUNT_PASSWORD); 
     URL metafeedUrl = new URL(SPREADSHEET_URL); 
     SpreadsheetEntry spreadsheet = service.getEntry(metafeedUrl, SpreadsheetEntry.class); 
     URL listFeedUrl = ((WorksheetEntry) spreadsheet.getWorksheets().get(0)).getListFeedUrl(); 
     ListFeed feed = (ListFeed) service.getFeed(listFeedUrl, ListFeed.class); 
     for(ListEntry entry : feed.getEntries()) 
     { 
      System.out.println("new row"); 
      for(String tag : entry.getCustomElements().getTags()) 
      { 
      System.out.println("  "+tag + ": " + entry.getCustomElements().getValue(tag)); 
      } 

     } 

     } 

} 

我收到以下錯誤上運行我的代碼

您必須添加google-collections.jar到類路徑中。
