我正在尝试使用该twitter4j库从推特流中获取随机样本并打印推文的用户名和文本。

我不确定我是否理解正确的术语OAuth。这是我需要为我的帐户获得的东西，还是只有在访问其他私人帐户时才需要？

这是我的代码：

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();
        }   
}

配置生成器类

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();
}

当我运行时，Twit4jEx1我得到以下信息：

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)

有什么建议么？

您的 ConfigurationBuilder 类试图在初始化块中而不是在构造函数或方法中运行代码。

我认为您的意思是：

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();
    }
}

然后你可以添加适当的吸气剂或其他东西。确保在主要功能中使用 MyConfigurationBuilder。
