SubjectEsServiceImpl.java
1.querySubjectList方法根据查询请求进行查询
Override
public PageResultSubjectInfoEs querySubjectList(SubjectInfoEs req) {// 构建一个返回的分页对象PageResultSubjectInfoEs pageResult new PageResult();// 根据信息构建一个查询请求对象EsSearchRequest esSearchRequest createSearchListQuery(req);// 获得分页查询结果SearchResponse searchResponse EsRestClient.searchWithTermQuery(getEsIndexInfo(), esSearchRequest);// 构建一个要返回的数据对象ListSubjectInfoEs subjectInfoEsList new LinkedList();// 得到命中的数据SearchHits searchHits searchResponse.getHits();if (searchHits null || searchHits.getHits() null) {pageResult.setPageNo(req.getPageNo());pageResult.setPageSize(req.getPageSize());pageResult.setRecords(subjectInfoEsList);pageResult.setTotal(0);return pageResult;}// 如果有命中的SearchHit[] hits searchHits.getHits();for (SearchHit hit : hits) {// 将每个hit都转换为SubjectInfoEs然后将其放到要返回的数据对象中SubjectInfoEs subjectInfoEs convertHit2SubjectInfoEs(hit);subjectInfoEsList.add(subjectInfoEs);}// 构建分页对象pageResult.setPageNo(req.getPageNo());pageResult.setPageSize(req.getPageSize());pageResult.setRecords(subjectInfoEsList);pageResult.setTotal(Long.valueOf(searchHits.getTotalHits().value).intValue());return pageResult;
}2.convertHit2SubjectInfoEs方法将每一个hit转换为SubjectInfoEs
/*** 将每一个hit转换为SubjectInfoEs* param hit* return*/
private SubjectInfoEs convertHit2SubjectInfoEs(SearchHit hit) {MapString, Object sourceAsMap hit.getSourceAsMap();if (CollectionUtils.isEmpty(sourceAsMap)) {return null;}SubjectInfoEs result new SubjectInfoEs();// 封装基本数据result.setSubjectId(MapUtils.getLong(sourceAsMap, EsSubjectFields.SUBJECT_ID));result.setSubjectName(MapUtils.getString(sourceAsMap, EsSubjectFields.SUBJECT_NAME));result.setSubjectAnswer(MapUtils.getString(sourceAsMap, EsSubjectFields.SUBJECT_ANSWER));result.setDocId(MapUtils.getLong(sourceAsMap, EsSubjectFields.DOC_ID));result.setSubjectType(MapUtils.getInteger(sourceAsMap, EsSubjectFields.SUBJECT_TYPE));result.setScore(new BigDecimal(String.valueOf(hit.getScore())).multiply(new BigDecimal(100.00).setScale(2, RoundingMode.HALF_UP)));//处理name的高亮MapString, HighlightField highlightFields hit.getHighlightFields();HighlightField subjectNameField highlightFields.get(EsSubjectFields.SUBJECT_NAME);if(Objects.nonNull(subjectNameField)){Text[] fragments subjectNameField.getFragments();StringBuilder subjectNameBuilder new StringBuilder();for (Text fragment : fragments) {subjectNameBuilder.append(fragment);}result.setSubjectName(subjectNameBuilder.toString());}//处理答案高亮HighlightField subjectAnswerField highlightFields.get(EsSubjectFields.SUBJECT_ANSWER);if(Objects.nonNull(subjectAnswerField)){Text[] fragments subjectAnswerField.getFragments();StringBuilder subjectAnswerBuilder new StringBuilder();for (Text fragment : fragments) {subjectAnswerBuilder.append(fragment);}result.setSubjectAnswer(subjectAnswerBuilder.toString());}return result;
}3.根据信息构建一个查询请求对象 /*** 根据信息构建一个查询请求对象* param req* return*/private EsSearchRequest createSearchListQuery(SubjectInfoEs req) {EsSearchRequest esSearchRequest new EsSearchRequest();// bq用来组合查询条件BoolQueryBuilder bq new BoolQueryBuilder();// 查询条件1是根据题目名称查询MatchQueryBuilder subjectNameQueryBuilder QueryBuilders.matchQuery(EsSubjectFields.SUBJECT_NAME, req.getKeyWord());// 查询条件2是根据题目的答案查询MatchQueryBuilder subjectAnswerQueryBuilder QueryBuilders.matchQuery(EsSubjectFields.SUBJECT_ANSWER, req.getKeyWord());// 使用bq关联两个查询条件should就相当于或者就是两个都查bq.should(subjectNameQueryBuilder);// 让题目名的权重高2subjectNameQueryBuilder.boost(2);bq.should(subjectAnswerQueryBuilder);// 查询条件3是只查询简答题MatchQueryBuilder subjectTypeQueryBuilder QueryBuilders.matchQuery(EsSubjectFields.SUBJECT_TYPE, SubjectInfoTypeEnum.BRIEF.getCode());// 必须是简答题bq.must(subjectTypeQueryBuilder);// 至少命中一个shouldbq.minimumShouldMatch(1);// 增加高亮HighlightBuilder highlightBuilder new HighlightBuilder().field(*).requireFieldMatch(false);highlightBuilder.preTags(span style \color:red\);highlightBuilder.postTags(/span);// 组装请求// bqesSearchRequest.setBq(bq);// 高亮esSearchRequest.setHighlightBuilder(highlightBuilder);// 匹配字段一般是全部esSearchRequest.setFields(EsSubjectFields.FIELD_QUERY);// 返回分页查询的结果// 当前页是从第几条记录开始下标从1开始esSearchRequest.setFrom((req.getPageNo() - 1) * req.getPageSize());// 页面大小esSearchRequest.setSize(req.getPageSize());// 返回分页查询的结果// 不需要快照缓存esSearchRequest.setNeedScroll(false);return esSearchRequest;}2.简单测试
1.TestFeignController.java RequestMapping(/querySubjectByKeyword)public void querySubjectByKeyword() {SubjectInfoEs subjectInfoEs new SubjectInfoEs();subjectInfoEs.setKeyWord(简答题目);PageResultSubjectInfoEs subjectInfoEsPageResult subjectEsService.querySubjectList(subjectInfoEs);// 打印log.info(querySubjectByKeyword: JSON.toJSONString(subjectInfoEsPageResult));}
}2.新增几条记录 2.查询 3.结果高亮显示 3.加上控制层的实现
1.DTO和BO都加上keyWord属性 2.SubjectController.java
/*** 全文检索* param subjectInfoDTO* return*/
PostMapping(/getSubjectPageBySearch)
public ResultSubjectInfoEs getSubjectPageBySearch(RequestBody SubjectInfoDTO subjectInfoDTO) {try {// 打印日志if (log.isInfoEnabled()) {log.info(SubjectController getSubjectPageBySearch SubjectInfoDTO, subjectInfoDTO:{}, JSON.toJSONString(subjectInfoDTO));}// 参数校验Preconditions.checkArgument(StringUtils.isNotBlank(subjectInfoDTO.getKeyWord()), 关键字不能为空);// DTO转BOSubjectInfoBO subjectInfoBO SubjectInfoDTOConverter.INSTANCE.convertDTO2BO(subjectInfoDTO);// 设置分页参数subjectInfoBO.setPageNo(subjectInfoDTO.getPageNo());subjectInfoBO.setPageSize(subjectInfoDTO.getPageSize());// 全文检索PageResultSubjectInfoEs boPageResult subjectInfoDomainService.getSubjectPageBySearch(subjectInfoBO);return Result.ok(boPageResult);} catch (Exception e) {log.error(SubjectController getSubjectPageBySearch error, subjectInfoDTO:{}, e.getMessage(), e);return Result.fail(全文检索失败);}
}3.sun-club-domain
1.SubjectInfoDomainService.java
/*** 全文检索* param subjectInfoBO* return*/
PageResultSubjectInfoEs getSubjectPageBySearch(SubjectInfoBO subjectInfoBO);2.SubjectInfoDomainServiceImpl.java
Override
public PageResultSubjectInfoEs getSubjectPageBySearch(SubjectInfoBO subjectInfoBO) {// 将bo转换为entitySubjectInfoEs subjectInfoEs new SubjectInfoEs();subjectInfoEs.setKeyWord(subjectInfoBO.getKeyWord());subjectInfoEs.setPageNo(subjectInfoBO.getPageNo());subjectInfoEs.setPageSize(subjectInfoBO.getPageSize());// 全文检索PageResultSubjectInfoEs subjectInfoEsPageResult subjectEsService.querySubjectList(subjectInfoEs);return subjectInfoEsPageResult;
}4.测试
1.es报错requires query value 2.发现转换器没有将keyWord转换所以clean-package一下maven即可 3.重新测试
