请在以下代码中找到实现。
请将 twitter4j-core-2.2.6.jar 和 twitter4j-stream-2.2.6.jar 添加到您的构建路径中。

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

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

    }
}

帮助很大。非常感谢@SamikBandyopadhyay
即使应用程序关闭，是否也可以让这个监听器保持活动状态？
它实际上创建了一个监听线程并继续监听..所以你没有关闭应用程序。
OnDirectMessage 不工作。我正在使用twitterStream.sample();，因为twitterStream.user(); 没有提供任何帮助
