需求：

        多层级关系，需要修改es_KIE下medical_ner,case_info中字段的值

参考网上帖子修改的写法：

request.index(esInfo.getIndex()) //索引名.id(timelineSearch.getId())//id.doc(XContentFactory.jsonBuilder().startObject().field("es_KIE.case_info.hosptial",timelineSearch.getHospital()).field("es_KIE.medical_ner.symptom",timelineSearch.getSymptom()).field("es_KIE.medical_ner.cure", timelineSearch.getCure()).field("es_KIE.medical_ner.es_map_cls",timelineSearch.getEsMapCls()).endObject());

 执行完会发现响应"OK"，没有报错，但是es库里值未改变

成功修改的写法：(多层嵌套)

        HashMap<String,Object> medicalNerMap = new HashMap<>();medicalNerMap.put("symptom",timelineSearch.getSymptom());medicalNerMap.put("cure",timelineSearch.getCure());HashMap<String, Object> caseInfoMap = new HashMap<>();caseInfoMap.put("hospital",timelineSearch.getHospital());HashMap<String,Object> esKIEMap = new HashMap<>();esKIEMap.put("medical_ner",medicalNerMap);esKIEMap.put("case_info",caseInfoMap);esKIEMap.put("es_map_cls",timelineSearch.getEsMapCls());HashMap<String,Object> bodyMap = new HashMap<>();bodyMap.put("es_KIE", esKIEMap);UpdateRequest request =new UpdateRequest(esInfo.getIndex(),timelineSearch.getId());request.doc(JSON.toJSONString(bodyMap), XContentType.JSON);UpdateResponse response =         restHighLevelClient.update(request,RequestOptions.DEFAULT);

捕获下异常就可以KQL：
POST common_dev/_update/0000739386_00
{"doc":{"es_KIE":{"medical_ner":{"symptom":["xxx","xxx"],"cure":["xxx","xxx"]},"case_info":{"hospital":"xxxx"},"es_map_cls":"xxxx"}  }
}
