Java调用Google Analytics API实现网站统计

下面代码是我根据Google官方文档修改并注释的一段代码，就可以实现访问量等信息的统计了。
[java]  
package cn.edu.KFC.bean; 
import com.google.gdata.client.analytics.AnalyticsService; 
import com.google.gdata.client.analytics.DataQuery; 
import com.google.gdata.data.analytics.AccountEntry; 
import com.google.gdata.data.analytics.AccountFeed; 
import com.google.gdata.data.analytics.DataEntry; 
import com.google.gdata.data.analytics.DataFeed; 
import com.google.gdata.util.AuthenticationException; 
import com.google.gdata.util.ServiceException; 
import java.io.IOException; 
import java.net.MalformedURLException; 
import java.net.URL;  
public class GoogleAnalytics { 
    // 使用ClientLogin 方法访问Google Analytics。其中，两个常量分别存储用户名和密码。 
    private static final String CLIENT_USERNAME = "anyone@gmail.com"; //Google 帐号 
    private static final String CLIENT_PASS = "1234567";  //Google 密码 
    private static final String TABLE_ID = "ga:715123"; //此帐号有权访问的Google Analytics配置文件的TABLE ID 
 
    public void myTest() { 
        try { 
            /*
             * 系统创建服务对象。服务对象的参数是一个代表应用程序名称的字符串。随后，系统将采用 setUserCredentials 方法来处理
             * Google Analytics（分析）授权。
             */ 
            // Service Object to work with the Google Analytics Data Export API. 
            AnalyticsService analyticsService = new AnalyticsService("gaExportAPI_acctSample_v2.0"); 
            // Client Login Authorization. 
            analyticsService.setUserCredentials(CLIENT_USERNAME, CLIENT_PASS); 
 
            // Get data from the Account Feed. 
            getAccountFeed(analyticsService);  //获取帐号信息 
 
            // Access the Data Feed if the Table Id has been set. 
            if (!TABLE_ID.isEmpty()) { 
                // Get profile data from the Data Feed.
                getDataFeed(analyticsService);  //获取数据信息（包括"指标"和"维度"） 
            } 
        } catch (AuthenticationException e) { 
            System.err.println("Authentication failed : " + e.getMessage()); 
            return; 
        } catch (IOException e) { 
            System.err.println("Network error trying to retrieve feed: " 
                    + e.getMessage()); 
            return; 
        } catch (ServiceException e) { 
            System.err.println("Analytics API responded with an error message: " 
                            + e.getMessage()); 
            return; 
        } 
    } 
    /**
     * 获取帐号feed
     * @param analyticsService
     * @throws IOException
     * @throws MalformedURLException
     * @throws ServiceException
     */ 
    private static void getAccountFeed(AnalyticsService analyticsService) 
            throws IOException, MalformedURLException, ServiceException { 
        // Construct query from a string. 
        URL queryUrl = new URL("https://www.google.com/analytics/feeds/accounts/default?max-results=50"); 
        // Make request to the API. 
        AccountFeed accountFeed = analyticsService.getFeed(queryUrl, AccountFeed.class); 
        // Output the data to the screen. 
        System.out.println("-------- Account Feed Results --------"); 
        for (AccountEntry entry : accountFeed.getEntries()) { 
            System.out.println("\nAccount Name  = " 
                    + entry.getProperty("ga:accountName")

                    + "\nProfile Id    = " + entry.getProperty("ga:profileId")  //配置文件编号 
                    + "\nTable Id      = " + entry.getTableId().getValue());   //配置文件的Table Id 
        } 
    } 
    /**
     * 获取指标和维度信息

     * @throws ServiceException
     */ 
    private static void getDataFeed(AnalyticsService analyticsService) 
            throws IOException, MalformedURLException, ServiceException {
