使用ElasticsearchRestTemplate，elasticesearchTemplate已经过期

  @Autowired    ElasticsearchRestTemplate restTemplate;  @Test     public void testEs(){         MyEs myEs = new MyEs();         myEs.setUsername("李四");         myEs.setSex(false);         myEs.setAge(18);         myEs.setBirth(LocalDate.now());         myEs.setId(1L);          ArrayList<MyEs.Son> sons = new ArrayList<>();         MyEs.Son son = new MyEs.Son();         son.setAge(1);         son.setUsername("礼物");         sons.add(son);         MyEs.Son son1 = new MyEs.Son();         son1.setAge(2);         son1.setUsername("理想");         sons.add(son1);         myEs.setChildren(sons);         restTemplate.save(myEs);     } 

@Test     void test2() {         TermsAggregationBuilder aggId = AggregationBuilders.terms("aggId").field("id");         aggId.subAggregation(AggregationBuilders.terms("aggAge").field("age"));         NativeSearchQuery query = new NativeSearchQueryBuilder()                 .withQuery(QueryBuilders.matchQuery("username", "李四"))                 .addAggregation(aggId)                 .withSort(SortBuilders.fieldSort("id").order(SortOrder.DESC))                 .withHighlightBuilder(new HighlightBuilder().field("username")                         .preTags("<span style='color:red;'>").postTags("</span>"))                 .withPageable(PageRequest.of(1,5))                 .build();              SearchHits<MyEs> search = restTemplate.search(query, MyEs.class);         List<MyEs> myess = search.getSearchHits().stream().map(item -> {             MyEs myEs = item.getContent();             myEs.setUsername(item.getHighlightField("username").get(0));             return myEs;         }).collect(Collectors.toList());          System.out.println(myess); 

使用Spring5.2。

升级到Elasticsearch7.6.2。

弃用TransportClient使用。

实现大多数可用于索引映射的映射类型。

移除JacksonObjectMapper，现在使用MappingElasticsearchConverter

清理*Operations接口中的API，对方法进行分组和重命名，使其与ElasticsearchAPI匹配，弃用旧方法，与其他方法SpringData模块保持一致。

引入SearchHit类表示文档和文档的相关结果元数据(即sortValues）。

引入SearchHits类表示整个搜索结果和完整搜索结果的元数据(即max_score）。

引入SearchPage类表示包含SearchHits实例分页结果。

引入GeoDistanceOrder能按地理距离排序的类

实施审计支持

实现生命周期实体回调
