使用Google plus API而不使用Google App引擎

Question

我可以在我的简单Java应用程序中直接调用G + API方法访问我的G +配置文件中的公共数据，而不会绕过＆＃34; Google引擎＆＃34; ？那就是使用谷歌API作为我的应用程序中的任何其他jar？

程序是这样的：

import java.io.IOException;
import java.io.Writer;
import com.google.api.client.extensions.appengine.http.UrlFetchTransport;
import com.google.api.client.http.HttpTransport;
import com.google.api.client.json.JsonFactory;
import com.google.api.client.json.jackson2.JacksonFactory;
import com.google.api.services.plus.Plus;
import com.google.api.services.plus.PlusRequestInitializer;
import com.google.api.services.plus.model.Activity;
import com.google.api.services.plus.model.ActivityFeed;
import com.google.api.services.plus.Plus.Builder;
import java.util.List;

public class Main {

    private static final String API_KEY = "dfhsdgdgdfhd";
    private static final long serialVersionUID = 1;

    public static void main( String[] args ){
        HttpTransport httpTransport = new UrlFetchTransport();
        JsonFactory jsonFactory = new JacksonFactory();

        Plus plus = new Plus.Builder(httpTransport, jsonFactory,     
        null).setApplicationName("TestGoogleApi")
        .setGoogleClientRequestInitializer(new   
        PlusRequestInitializer(API_KEY))
        .build();

        ActivityFeed myActivityfeed;

        myActivityfeed = plus.activities().search("Google").execute();
        List<Activity> myActivities = myActivityfeed.getItems();

        for (Activity a : myActivities) {  
        System.out.println(a.getTitle());
        }

    }

 }
