这是报错 这是config配置类 @Configuration public class SpringSensitiveWordConfig { @Resource private WordDeny wordDeny; /**初始化引导类

• @return 初始化引导类
• @since 1.0.0
• */ @Bean public SensitiveWordBs sensitiveWordBs() { SensitiveWordBs sensitiveWordBs = SensitiveWordBs.newInstance() .wordDeny(WordDenys.chains(WordDenys.defaults(),wordDeny)) .enableNumCheck(true) .enableEmailCheck(true) .enableUrlCheck(true) .init(); return sensitiveWordBs; } } 这是自定义的铭感词类 @Service public class WordDeny implements IWordDeny { @Resource private SensitiveWordMapper sensitiveWordMapper; @Override public List deny() { LambdaQueryWrapper queryWrapper=new LambdaQueryWrapper<>(); queryWrapper.eq(SensitiveWord::getStatus,0); List sensitiveWords = sensitiveWordMapper.selectList(queryWrapper); if(CollectionUtil.isNotEmpty(sensitiveWords)){ List list = sensitiveWords.stream().map(SensitiveWord::getSensitiveWord).toList(); return list; }else{ return null; } } }

黑名单那个接口,return null 改一下 改成 rerurn new ArrayList<>();

v0.18.1 已兼容 null 场景。
