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
