效果图

审核时，输入框高亮敏感词，并且能编辑

前端代码

列表高亮

      <el-table-columnlabel="标题"align="center"prop="publishTitle":show-overflow-tooltip="true"><template slot-scope="scope"><span v-html="highlightPublishTitle(scope.row)"></span></template></el-table-column>

    highlightPublishTitle(row){let text = row.publishTitlefor (const word of row.titleSensitiveWord) {const regex = new RegExp(word, 'g')text = text.replace(regex, `<span style="color: red;">${word}</span>`)}return text},

编辑表单输入框高亮

        <el-form-item label="标题" prop="publishTitle"><highlight-textareav-if="open"style="width: 100%;"placeholder="请输入":text="form.publishTitle"type="input"@change="(value) => {form.publishTitle = value}":highlightKey="form.titleSensitiveWord"></highlight-textarea></el-form-item>

后端代码

触发敏感词记录

 /*** 敏感词检查**/public void sensitiveWordCheck(SubPublishing subPublishing) {List<TzLySensitiveWordRecord> recordList = new ArrayList<>();Date nowDate = DateUtils.getNowDate();//找出标题的敏感词List<String> titleList = SensitiveWordHelper.findAll(subPublishing.getPublishTitle());TzLySensitiveWordRecord dbTitle = sensitiveWordRecordService.selectTzLySensitiveWordRecordByMessageIdAndSource(subPublishing.getId(), HYZR_TITLE);//插入if (ObjectUtil.isNull(dbTitle) && CollectionUtils.isNotEmpty(titleList)) {TzLySensitiveWordRecord record = new TzLySensitiveWordRecord();record.setWordId(null);// 敏感词IDrecord.setWord(StrUtil.join(",", titleList)); //敏感词record.setMessageId(subPublishing.getId());// 主键IDrecord.setUserId(Long.valueOf(subPublishing.getCreatorId()));// 发送人IDrecord.setUserName(subPublishing.getCreatorName());// 发送人姓名record.setMobile(subPublishing.getCreatorTel());// 发送人手机号record.setSendTime(nowDate);// 发送时间record.setIsDeleted(0);// 是否删除record.setCreatedDate(nowDate);// 创建时间record.setCreatedBy(Long.valueOf(subPublishing.getCreatorId()));// 创建人record.setSource(HYZR_TITLE);//消息来源 会员值日record.setMessage(subPublishing.getPublishTitle()); //记录实际发送消息record.setReplaceMessage(subPublishing.getPublishTitle()); //记录替换的消息recordList.add(record);//更新} else if (ObjectUtil.isNotNull(dbTitle)) {dbTitle.setWord(StrUtil.join(",", titleList)); //敏感词dbTitle.setLastModifiedDate(nowDate);// 修改时间dbTitle.setLastModifiedBy(Long.valueOf(subPublishing.getCreatorId()));// 修改人dbTitle.setMessage(subPublishing.getPublishTitle()); //记录实际发送消息dbTitle.setReplaceMessage(subPublishing.getPublishTitle()); //记录替换的消息recordList.add( dbTitle);}TzLySensitiveWordRecord dbContent = sensitiveWordRecordService.selectTzLySensitiveWordRecordByMessageIdAndSource(subPublishing.getId(), HYZR_CONTENT);if (CollectionUtils.isNotEmpty(recordList)) {sensitiveWordRecordService.saveOrUpdateBatch(recordList);}}

回显敏感词记录

        SubPublishing subPublishing = this.getById(id);//查询是否触发敏感词Map<String, TzLySensitiveWordRecord> sensitiveWordRecordMap = sensitiveWordRecordService.selectListByMessageId(id).stream().collect(Collectors.toMap(TzLySensitiveWordRecord::getSource, o -> o));if (!sensitiveWordRecordMap.isEmpty()) {TzLySensitiveWordRecord title = sensitiveWordRecordMap.get(HYZR_TITLE);if (ObjectUtil.isNotNull(title)) {subPublishing.setTitleSensitiveWord(StrUtil.split(title.getWord(), ","));}
