如何從twitter流中獲取樣本並將其打印到屏幕

我試圖使用twitter4j庫從twitter流中獲取隨機樣本並打印推文的用戶名和文本。如何從twitter流中獲取樣本並將其打印到屏幕

至於OAuth，我不確定我是否理解正確的術語。這是我需要爲我的帳戶獲得的東西，還是僅在訪問其他私人帳戶時才需要這些東西？

這裏是我的代碼：

package tweet1; 

import java.io.IOException; 

import twitter4j.Status; 
import twitter4j.StatusDeletionNotice; 
import twitter4j.StatusListener; 
import twitter4j.TwitterException; 
import twitter4j.TwitterStream; 
import twitter4j.TwitterStreamFactory; 
import twitter4j.auth.BasicAuthorization; 

public class Twit4jEx1 { 

    /** 
    * @param args 
    */ 
     // TODO Auto-generated method stub 
     public static void main(String[] args) throws TwitterException, IOException{ 
//   BasicAuthorization ba1 = new BasicAuthorization("userName", "pword"); 
      ConfigurationBuilder cb = new ConfigurationBuilder(); 

      StatusListener listener = new StatusListener(){ 
       public void onStatus(Status status) { 
        System.out.println(status.getUser().getName() + " : " + status.getText()); 
       } 
       public void onDeletionNotice(StatusDeletionNotice statusDeletionNotice) {} 
       public void onTrackLimitationNotice(int numberOfLimitedStatuses) {} 
       public void onException(Exception ex) { 
        ex.printStackTrace(); 
       } 
       @Override 
       public void onScrubGeo(long arg0, long arg1) { 
        // TODO Auto-generated method stub 

       } 
      }; 
      TwitterStream twitterStream = new TwitterStreamFactory().getInstance(); 
      // sample() method internally creates a thread which manipulates TwitterStream and calls these adequate listener methods continuously. 
      twitterStream.sample(); 
     } 
}

ConfigurationBuilder類

package tweet1; 

import twitter4j.Twitter; 
import twitter4j.TwitterFactory; 
//import twitter4j.conf.ConfigurationBuilder; 

public class ConfigurationBuilder { 
    ConfigurationBuilder cb = new ConfigurationBuilder(); 
    cb.setDebugEnabled(true) 
     .setOAuthConsumerKey("***") 
     .setOAuthConsumerSecret("***") 
     .setOAuthAccessToken("***") 
     .setOAuthAccessTokenSecret("***"); 
    TwitterFactory tf = new TwitterFactory(cb.build()); 
    Twitter twitter = tf.getInstance(); 
}

當我運行Twit4jEx1我得到如下：

Exception in thread "main" java.lang.Error: Unresolved compilation problems: 
    Syntax error on token(s), misplaced construct(s) 
    Syntax error on token "setDebugEnabled", = expected after this token 

    at tweet1.ConfigurationBuilder.<init>(ConfigurationBuilder.java:9) 
    at tweet1.Twit4jEx1.main(Twit4jEx1.java:21)

有什麼建議？

@AnujKulkarni：是的，這就是我從中獲得代碼的地方。 – screechOwl

您的類ConfigurationBuilder試圖在初始化塊中而不是在構造函數或方法中運行代碼。

我想你的意思是有類似：

public class MyConfigurationBuilder { 
    private ConfigurationBuilder cb; 
    private Twitter twitter; 

    public MyConfigurationBuilder() { 
     cb = new ConfigurationBuilder(); 
     cb.setDebugEnabled(true) 
     .setOAuthConsumerKey("***") 
     .setOAuthConsumerSecret("***") 
     .setOAuthAccessToken("***") 
     .setOAuthAccessTokenSecret("***"); 
     TwitterFactory tf = new TwitterFactory(cb.build()); 
     twitter = tf.getInstance(); 
    } 
}

然後你就可以添加相應的getter方法什麼的。確保在你的主要功能中使用MyConfigurationBuilder。
