这是为什么?我怎样才能解决这个问题?这是我的代码:

Why is this? How can I fix this? Here is my code:

import java.io.File;
import java.io.IOException;
import java.net.URL;
import java.security.GeneralSecurityException;
import java.util.Arrays;
import java.util.List;

import com.google.gdata.util.ServiceException;

public class TestSpreadsheet {

    private static final String SERVICE_ACCOUNT_EMAIL = "[e-mail]";

    private static final File SERVICE_ACCOUNT_PKCS12_FILE = new File("./key.p12");
    private static SpreadsheetService SPREADSHEETSERVICE;

    public static void main(String[] args) throws GeneralSecurityException, IOException, ServiceException {


           HttpTransport httpTransport = new NetHttpTransport();
           JacksonFactory jsonFactory = new JacksonFactory();
           String [] SCOPESArray= {"https://spreadsheets.google.com/feeds", "https://docs.google.com/feeds"};

           List<String> SCOPES = Arrays.asList("https://spreadsheets.google.com/feeds", "https://spreadsheets.google.com/feeds/spreadsheets/private/full", "https://docs.google.com/feeds");

           //final List<String> SCOPES = Arrays.asList(SCOPESArray);
           GoogleCredential credential = new GoogleCredential.Builder()
             .setTransport(httpTransport)
             .setJsonFactory(jsonFactory)
             .setServiceAccountId(SERVICE_ACCOUNT_EMAIL)
             .setServiceAccountScopes(SCOPES)
             .setServiceAccountPrivateKeyFromP12File(SERVICE_ACCOUNT_PKCS12_FILE)
             .build();
           credential.refreshToken();
           SPREADSHEETSERVICE = new SpreadsheetService("test");
           SPREADSHEETSERVICE.setOAuth2Credentials(credential);

           URL SPREADSHEET_FEED_URL;
            SPREADSHEET_FEED_URL = new URL("https://spreadsheets.google.com/feeds/spreadsheets/private/full");

            SpreadsheetFeed feed = SPREADSHEETSERVICE.getFeed(SPREADSHEET_FEED_URL, SpreadsheetFeed.class);
            List<SpreadsheetEntry> spreadsheets = feed.getEntries();

            if (spreadsheets.size() == 0) {
                System.out.println("No spreadsheets found.");
            }
    }

}

推荐答案

我找到了解决此问题的方法.例如，在[e-mail]是服务帐户ID的情况下，我们需要使用服务帐户ID共享电子表格.我们需要使用该ID共享电子表格.

I found the solution to this problem. We need to share the spreadsheet with service account id for example in the case above [e-mail] is service account id, and we need to share the spreadsheets with this id.
