1、添加依赖

<dependency>
            <groupId>com.github.houbb</groupId>
            <artifactId>sensitive-word</artifactId>
            <version>0.17.0</version>
        </dependency>
        <dependency>
            <groupId>junit</groupId>
            <artifactId>junit</artifactId>
            <version>4.13.1</version>
            <scope>test</scope>
        </dependency>

2、SensitiveConfig
 

@Configuration
public class SensitiveConfig {

    @Autowired
    private MyWordAllow myWordAllow;

    @Autowired
    private MyWordDeny myWordDeny;

    /**
     * 初始化引导类
     * @return 初始化引导类
     * @since 1.0.0
     */
    @Bean
    public SensitiveWordBs sensitiveWordBs() {
        // 配置默认敏感词 + 自定义敏感词
        IWordDeny wordDeny = WordDenys.chains(WordDenys.defaults(), myWordDeny);
        // 配置默认非敏感词 + 自定义非敏感词

        IWordAllow wordAllow = WordAllows.chains(WordAllows.defaults(), myWordAllow);

        return SensitiveWordBs.newInstance()
                // 忽略大小写
                .ignoreCase(true)
                // 忽略半角圆角
                .ignoreWidth(true)
                // 忽略数字的写法
                .ignoreNumStyle(true)
                // 忽略中文的书写格式：简繁体
                .ignoreChineseStyle(true)
                // 忽略英文的书写格式
                .ignoreEnglishStyle(true)
                // 忽略重复词
                .ignoreRepeat(false)
                // 是否启用数字检测
                .enableNumCheck(true)
                // 是否启用邮箱检测
                .enableEmailCheck(true)
                // 是否启用链接检测
                .enableUrlCheck(true)
                // 数字检测，自定义指定长度
                .numCheckLen(8)
                // 配置自定义敏感词
                .wordDeny(wordDeny)
                // 配置非自定义敏感词
                .wordAllow(wordAllow)
                .init();
    }

3、自定义 敏感词

@Slf4j
@Component
public class MyWordDeny implements IWordDeny {

    @Override
    public List<String> deny() {
        List<String> list = new ArrayList<String>();;
        try {
            Resource mySensitiveWords = new ClassPathResource("sensitive/mySensitiveWords.txt");
            Path mySensitiveWordsPath = Paths.get(mySensitiveWords.getFile().getPath());
            list =  Files.readAllLines(mySensitiveWordsPath, StandardCharsets.UTF_8);
        } catch (IOException ioException) {
            log.error("读取敏感词文件错误！"+ ioException.getMessage());
        }
        return list;
    }

}

自定义非敏感词

@Slf4j
@Component
public class MyWordAllow implements IWordAllow {

    @Override
    public List<String> allow() {
        List<String> list = new ArrayList<String>();;
        try {
            Resource myAllowWords = new ClassPathResource("sensitive/myAllowWords.txt");
            Path myAllowWordsPath = Paths.get(myAllowWords.getFile().getPath());
            list =  Files.readAllLines(myAllowWordsPath, StandardCharsets.UTF_8);
        } catch (IOException ioException) {
            log.error("读取非敏感词文件错误！"+ ioException.getMessage());
        }
        return list;
    }

}

3、 Service类
 

@Component
public class SensitiveWordService {

    @Autowired
    private SensitiveWordBs sensitiveWordBs;

    // 刷新敏感词库与非敏感词库缓存
    public void refresh(){
        sensitiveWordBs.init();
    }
    // 判断是否含有敏感词
    public boolean contains(String text){
        return sensitiveWordBs.contains(text);
    }

    // 使用默认替换符 * 进行替换敏感词
    public String replace(String text){
        return sensitiveWordBs.replace(text);
    }

    // 返回所有敏感词
    public List<String> findAll(String text){
        return sensitiveWordBs.findAll(text);
    }
}

 4、测试类

@RunWith(SpringRunner.class)
@SpringBootTest(classes = {MyGptApplication.class}, webEnvironment = SpringBootTest.WebEnvironment.RANDOM_PORT)
@ContextConfiguration(classes = MyGptApplication.class)
public class SensitiveTest {

    @Autowired
    private SensitiveWordService sensitiveWordService;

    @Test
    public void test() {
        String s = "赌博 test";
        String s1 = sensitiveWordService.replace(s);
        Boolean flag = sensitiveWordService.contains(s);
        if (flag) {
            System.out.println("请调整问题，避免受限内容，我们将更好地协助您。");
        }
        System.out.println(s1);
    }

}

5、文本目录
