Java实现敏感词过滤功能

敏感词过滤功能实现

1.GitHub上下载敏感词文件

2.将敏感词文件放在resources目录下

在业务中可以将文本中的敏感词写入数据库便于管理。
3.提供实现类demo
代码编写思路如下：1.将敏感词加载到list中，2.添加到StringSearch中，3.校验，判断文本是否属于敏感词汇。

import toolgood.words.StringSearch;
import java.io.BufferedReader;
import java.io.FileNotFoundException;
import java.io.FileReader;
import java.io.IOException;
import java.util.ArrayList;
import java.util.List;public class TestWords {public static void main(String[] args) {String filePath = "src/main/resources/sensi_words.txt";try(BufferedReader reader = new BufferedReader(new FileReader(filePath))) {String line;List<String> list = new ArrayList<>();StringSearch search = new StringSearch();while ((line = reader.readLine()) != null){if (!list.contains(line)){list.add(line);}}search.SetKeywords(list);String[] words = new String[]{"草","草他妈","你是狗","你是做过鸡嘛","干你妈","煞笔","你是shabi","我有点呆"};for (int i = 0; i < words.length; i++) {boolean res = search.ContainsAny(words[i]);System.out.println(res ==  true ? words[i]+":敏感词": words[i]+":非敏感词");}System.out.println("---------------------------");for (int i = 0; i < words.length; i++) {//脱敏处理boolean res = search.ContainsAny(words[i]);System.out.println(res ==  true ? search.Replace(words[i],'*') : words[i]);}} catch (FileNotFoundException e) {throw new RuntimeException(e);} catch (IOException e) {throw new RuntimeException(e);}}
}

4.输出结果展示

注意：输出结果中，敏感词已经进行*号处理
