twitter4j是否爲傳入的直接消息提供事件偵聽器？

Question

我正在開發一個使用twitter4j API與Twitter進行交互的應用程序。這個API是否提供了一個事件偵聽器來接收直接消息？

請在下面的代碼中找到實現。
請將twitter4j-core-2.2.6.jar & twitter4j-stream-2.2.6.jar添加到您的構建路徑。

package com.apt.java.test.twitterdemo; 

import java.util.List; 

import twitter4j.DirectMessage; 
import twitter4j.Status; 
import twitter4j.StatusDeletionNotice; 
import twitter4j.StatusListener; 
import twitter4j.Twitter; 
import twitter4j.TwitterException; 
import twitter4j.TwitterFactory; 
import twitter4j.TwitterStream; 
import twitter4j.TwitterStreamFactory; 
import twitter4j.User; 
import twitter4j.UserList; 
import twitter4j.UserStreamListener; 
import twitter4j.auth.AccessToken; 
import twitter4j.conf.ConfigurationBuilder; 

public class TwitterDemo { 
    private TwitterStream twitterStream; 
    private void initConfiguration(){ 
     ConfigurationBuilder cb = new ConfigurationBuilder(); 
     cb.setDebugEnabled(true) 
      .setOAuthConsumerKey("YOUR CONSUMER KEY") 
      .setOAuthConsumerSecret("YOUR CONSUMER SECRET"); 

     TwitterStreamFactory twitterStreamFactory = new TwitterStreamFactory(cb.build()); 
     twitterStream = twitterStreamFactory.getInstance(new AccessToken("YOUR ACCESS TOKEN", "YOUR ACCESS TOKEN SECRET")); 
     twitterStream.addListener(userStreamListener); 
     twitterStream.user(); 

    } 

    UserStreamListener userStreamListener = new UserStreamListener() { 

     @Override 
     public void onException(Exception arg0) { 
      // TODO Auto-generated method stub 

     }

     @Override 
     public void onUnblock(User arg0, User arg1) {

     @Override

     @Override

     } 
    }; 

    public static void main(String[] args){ 
     TwitterDemo demo = new TwitterDemo(); 
     demo.initConfiguration(); 

    }
