（原）java - 抽取ES数据动态添加到list数组集合中

 博客只提供【标题】中关键代码片段，其余为辅助代码，不过多展示，请理解 ~ ~

 //自定义 学科名称数组 ArrayList arraySubList = new ArrayList(); ArrayList arraySubIdList = new ArrayList(); if (elasticsearchRestTemplate.indexExists("s*******************b")) {     SearchQuery searchQuery = new NativeSearchQueryBuilder()      .withIndices("s************b")      .withTypes("_***************")      .withQuery(boolQuery)      .build();     //统计学生的发布课程信息     List s*************Os = elasticsearchRestTemplate.queryForList(searchQuery, S*************O.class);     //根据学生发布课程编号获取学段，学科基本信息     for (int i = 0; i < stuIssueD**********s.size(); i++) {  String strCourseId = stu************s.get(i).getCourse_base_id();  //课程统计  BoolQueryBuilder queryCourseInfo = QueryBuilders.boolQuery();  queryCourseInfo.must(QueryBuilders.termQuery("co******id", strCourseId));  SearchQuery queryCourse = new NativeSearchQueryBuilder()   .withIndices("s****************o")   .withTypes("_d************************")   .withQuery(queryCourseInfo)   .build();  List co*************List = elasticsearchRestTemplate.queryForList(queryCourse, C***********O.class);  for (int j = 0; j < co**********ist.size(); j++) {      BoolQueryBuilder querySubInfo = QueryBuilders.boolQuery();      //学段信息      if (StringUtils.isNotBlank(subjectId)) {   querySubInfo.must(QueryBuilders.termQuery("s******de", subjectId));      } else {   querySubInfo.must(QueryBuilders.termQuery("s***********de", courseVOFromESList.get(j).getBusiness_subject_id()));      }      //学科信息      if (StringUtils.isNotBlank(stageId)) {   querySubInfo.must(QueryBuilders.termQuery("s******de", stageId));      } else {   querySubInfo.must(QueryBuilders.termQuery("s*******de", courseVOFromESList.get(j).getBu*******_id()));      }      SearchQuery querySubjectInfo = new NativeSearchQueryBuilder().withIndices("st*********t").withTypes("_***********c").withQuery(querySubInfo).build();      List subList = elasticsearchRestTemplate.queryForList(querySubjectInfo, Su*********O.class);      //动态添加 - list数组     //动态添加 - list数组      arraySubList.add(subList.get(0).getSubject_name());      arraySubIdList.add(subList.get(0).getSubject_code());  }     }     List s**************List = homeworkService.getQuestionAndknowledgeTotal(s****************O);     for (int i = 0; i < st************List.size(); i++) {  //学生学习的课程数量  st**************List.get(i).setResourceAccount(s************s.size());  stud**************List.get(i).setSubjectId(subjectId);  //学科名称    subList.stream().map(S*******::getSubject_name).collect(Collectors.toList());//  studentSubResourceVOList.get(i).setSubjectName(subName.toString());     }      return studentSubResourceVOs; }
