我今天尝试整合springboot（2.1.5.RELEASE），es 是7.2 ，
第一步：在pom 加入依赖
<dependency>
            <groupId>org.elasticsearch</groupId>
            <artifactId>elasticsearch</artifactId>
            <version>7.2.0</version>
        </dependency>

        <dependency>
            <groupId>org.elasticsearch.client</groupId>
            <artifactId>elasticsearch-rest-high-level-client</artifactId>
            <version>7.2.0</version>
        </dependency>

第二步：application.yml 添加 es 服务
spring:
  elasticsearch:
    rest:
      uris: http://000.89.201.222:9200
如果是你自己本机的es ,其实是可以不用加的，看源码有默认值，如果是远程服务器要加
在RestClientProperties中查看
private List<String> uris = new ArrayList<>(
            Collections.singletonList("http://localhost:9200"));

第三部：少废话，直接上代码

    @Autowired
    private RestHighLevelClient restHighLevelClient;

  SearchRequest searchRequest = new SearchRequest("paomi");
        SearchSourceBuilder sourceBuilder = new SearchSourceBuilder();
        sourceBuilder.query(QueryBuilders.matchPhraseQuery("nickname", "纯爷们"));
        sourceBuilder.timeout(new TimeValue(60, TimeUnit.SECONDS));
        searchRequest.source(sourceBuilder);
        try {
            SearchResponse response = restHighLevelClient.search(searchRequest, RequestOptions.DEFAULT);
            Arrays.stream(response.getHits().getHits())
                    .forEach(i -> {

                    });
            System.out.println(response.getHits());
        } catch (IOException e) {
            e.printStackTrace();
        }
最后给开发者一个建议，对看看官网文档，其实es 官方文档写的很好
以下是官方客户端链接
https://www.elastic.co/guide/en/elasticsearch/client/java-rest/current/java-rest-high-document-get.html

PUT /test2/_doc/3
{
  "name": "suen1",
  "age": 23
}
POST/test2/_doc/3
{
  "name": "suen1",
  "age": 23
}
以上两个是一样的额，都可以更新啊求指导@
