如何使用Java编写CMS系统的反垃圾评论模块

import org.apache.commons.io.FileUtils;
import org.jsoup.Jsoup;

import java.io.File;
import java.io.IOException;
import java.util.List;

public class CommentFilter {

   public static void main(String[] args) throws IOException {
       // 加载训练数据集
       List<String> trainingData = FileUtils.readLines(new File("training_comments.txt"), "UTF-8");

       // 创建一个分类器实例
       Classifier classifier = new BayesianClassifier();

       // 对训练数据进行标记
       for (String comment : trainingData) {
           boolean isSpam = comment.startsWith("spam");
           String content = Jsoup.parse(comment.substring(5)).text();
           classifier.train(content, isSpam);
       }

       // 对新的评论进行分类
       String newComment = "This is a great article!";
       String cleanComment = Jsoup.parse(newComment).text();
       boolean isSpam = classifier.classify(cleanComment);

       if (isSpam) {
           System.out.println("This comment is spam!");
       } else {
           System.out.println("This comment is clean.");
       }
   }
}
