敏感字过滤器

最近项目中要写一个过滤器来过滤玩家的脏话，敏感字词。现在写了个工具能直接使用，希望能帮到大家，看到请给我个赞，谢谢啦哈哈。

1. 代码

package com.wang;

import java.io.FileInputStream;
import java.io.FileNotFoundException;
import java.io.FileReader;
import java.io.IOException;
import java.io.InputStreamReader;
import java.util.ArrayList;
import java.util.List;

public class KeyFilterUtil {
    /*
     * 分隔符 ,
     * */
  public static void main(String[] args) {
    String a = "妈的aaa";
    String b = KeyFilterUtil.getFilt(a);
    System.out.println("before filter:" + a);
    System.out.println("after filter:"+b);
  }
  public static String getFilt(String stringSrc){
    String s=readFile(KeyFilterUtil.class.getClassLoader()
            .getResource("").getPath() + "/keyfilters.txt");
    //从文件中获取敏感字存入list
    List<String> keyList = keywordsToList(s);
    System.out.println("length:" + keyList.size());
    String filterString = stringSrc;
    for (int i = 0; i < keyList.size(); i++) {
        System.out.println(keyList.get(i) + "keyList.get(i)");
      if(stringSrc.contains(keyList.get(i))){
        filterString = stringSrc.replace(keyList.get(i),"*");
      }
    }
//    System.out.println("before filter:" + stringSrc);
//    System.out.println("after filter:"+filterString);
    return filterString;
  }

  public static List<String> keywordsToList(String s) {
    System.out.println("过滤关键字:"); 
    System.out.println(s);
    String[]result =s.split(",");
    List<String> list = new ArrayList<>();
    for (int i = 0; i < result.length; i++) {
      list.add(result[i]);
    }
    return list;
  }

  public static String readFile(String fliename){
      StringBuffer strbf=new StringBuffer();
      String s=null;
      char[] buf=new char[1024];
      try {
      FileReader f=new FileReader(fliename);
//        InputStreamReader f=new InputStreamReader(new FileInputStream(fliename),"UTF-8");
      while(f.read(buf)>0){
      strbf.append(buf);
      }
        s=strbf.toString();
        return s;
      } catch (FileNotFoundException e) {
        e.printStackTrace();
        return null;
      } catch (IOException e) {
        e.printStackTrace();
        return null;
      }
  }
}

2. 目录结构

3. keyfilters.txt内放入敏感词汇，用英文逗号分隔开

4.过滤效果图
